Best Plagiarism Checkers Compared

Published on May 20, 2024 by Koen Driessen .

The best plagiarism checker should be able to detect plagiarism the most accurately, even if the original phrasing has been altered. The tool should also provide a clear, comprehensive plagiarism report.

To identify which plagiarism checker is best, we conducted in-depth research comparing the performance of 10 checkers. We uploaded plagiarized texts that were either directly copied and pasted or edited to varying degrees. In total, we used 140 sources to construct our test documents.

Overview of total scores per plagiarism checker, based on the amount of detected plagiarism:

Our process for comparing checkers, 1. scribbr review , 2. plagaware review, 3. quetext review, 4. viper review, 5. grammarly review, 6. plagiarism detector review, 7. copyleaks review, 8. smodin review, 9. compilatio review, 10. writer review, frequently asked questions about plagiarism checkers.

In order to find the best plagiarism checker, we analyzed different aspects of the tools, focusing on both depth and breadth.

We based our analysis on the following factors:

  • Access to the biggest and most varied database
  • Ability to detect the most plagiarism for the most source types
  • Ability to detect plagiarism when the plagiarized texts have been paraphrased
  • Highest quality of matches
  • Level of user-friendliness and trustworthiness

We used the same test documents, test date, evaluation criteria, and data analysis for each tool in order to objectively compare the plagiarism results side by side. This ensured that the results required very little interpretation on our part.

“Catches plagiarism more accurately than any other checker”

Scribbr Plagiarism Checker

  • Finds the most plagiarism and works for edited texts, too
  • Does not store or sell documents
  • Offers a happiness guarantee and live support
  • Offers a Self-Plagiarism Checker to check for self-plagiarism
  • Offers a limited free version
  • Quality comes at a price
  • Cannot work directly in the tool

Quality of matches

Scribbr performed well for all source types relevant to students, such as journal articles and dissertations.

Most importantly, Scribbr’s checker was the most successful at detecting plagiarism in source texts that had been heavily edited to mimic accidental paraphrasing plagiarism.

Scribbr was also able to find full matches. This means the entire plagiarized portion is matched correctly to just one source, rather than multiple incorrect sources.

The results are presented in a clear, downloadable overview. Different colors are used for different sources, making it easy for users to assess each plagiarism issue separately.

Issues can be fixed with Scribbr’s free citation generator , which generates proper citations for any missed or improperly cited sources.

Users can also choose to combine the Plagiarism Checker with the Self-Plagiarism Checker , which is unique to Scribbr. This tool allows users to upload their own unpublished documents in addition to the public database.

Instead of requiring users to subscribe to their services, Scribbr charges per plagiarism check ($19.95–$39.95, depending on the word count).

However, users are unable to work directly in the tool, and it is not possible to re-check your document for free.

Trustworthiness

Scribbr does not store the uploaded documents, sell them to third parties, or share them with academic institutions. Data is automatically deleted after 30 days, or students can opt to manually delete their document after the check.

Scribbr has live and responsive customer support to assist students in multiple languages. There is easy access to a plagiarism checker guide and other free resources about plagiarism.

Scribbr also has a happiness guarantee, where students receive a new check or refund if they aren’t satisfied for any reason.

Plagaware

  • Detects most of the plagiarism
  • Documents not stored in database
  • Multiple support options, but no live support
  • Difficult to read PDF reports
  • Does not work well for scholarly sources

Plagaware was often able to find full matches and attribute the text to the correct source. However, it performed poorly with heavily edited texts.

Sometimes, the tool did not correctly distinguish between separate plagiarized sources (i.e., it incorrectly attributed two consecutive paragraphs to the same source).

The website report is easy to navigate as it uses different colors for sources. The tool has a function that tells you how many words a plagiarized section has and gives a similarity percentage.

Unfortunately, the downloadable report is confusing to read as it uses only one color and doesn’t clearly link plagiarized text with a source.

Plagaware does not store files and does not sell uploaded content. Their website contains a contact form and phone number.

QueText

  • Users can work directly in the tool
  • Offers a citation assistant that helps with adding missing citations
  • Partial matches where one source text is matched to multiple sources
  • Reports are hard to read

Quetext detected about half the plagiarized text but was often unable to fully match the entire source text to one source. Instead, individual sentences get attributed to different sources.

The website states that Quetext checks against webpages and academic sources, but the tool does not in fact perform well for academic sources.

The website report sometimes did not correctly distinguish between plagiarized paragraphs and attributed them to the same source.

Quetext differentiates by severity of plagiarism in its online report: orange for partial matches and red for full matches. Otherwise, the same colors are used for different sources.

Users can work directly in the tool, and Quetext offers a citation assistant that helps generate the missing citations.

The original layout of the text is lost in both the website report and the downloadable report.

The tool does not store or re-upload your text, and it offers a help center with FAQs. There is no live support, but users can submit a help request on the website.

Viper Plagiarism Checker

  • Ability to compare your newest document with previously uploaded documents
  • Different colors for different source types
  • Documents get published on external websites if you use the free version
  • Performs poorly for scholarly sources
  • Report can be hard to read, due to partial matches

Viper found about half of the plagiarism when the source text was directly copied or lightly edited, but it struggled to find plagiarism in moderately and heavily edited texts.

The tool had average performance for most source types but struggled specifically with scholarly source types such as journal articles and dissertations. This makes this tool less useful for students.

When Viper flagged plagiarism, it often matched the entire passage to one source. While the downloadable report was somewhat difficult to read, it helpfully uses different colors for different sources.

Viper also allows users to check their text against their own previously uploaded documents, which may help to catch instances of self-plagiarism.

Viper stores previous submissions and shows matches with those texts.

The tool does not sell your document if you use the paid version (prices start at $3.95 per 5,000 words). However, if you use the free version, the document is uploaded to an internal database. After three months, the text is published on an external website as an example for other students. This is not good if the content of your text is confidential.

Viper does not have live support, but there is a contact form on the website.

Grammarly

  • Offers a language and citation assistant
  • Does not sell or share documents with other parties
  • Finds quite a low percentage of plagiarism
  • 100,000 character limit (14,000–25,000 words)
  • Same colors for different sources

Grammarly found a relatively low amount of plagiarism. It performed best with lightly edited texts. However, it scored below 50% in all other rounds of testing.

When it did find plagiarism, the tool was often able to find the right source. However, the matches were usually only partial and rarely included the entire plagiarized section.

The design is not very clear. As the tool is primarily used as a language checker, the plagiarism checker function is somewhat difficult to find. The tool uses the same color for all sources, making it hard to read.

The subscription comes with a language and style tool and offers a citation assistant that helps generate the missing citations. In addition, there is a 100,000 character limit for both the monthly plan ($30 per month) and the yearly plan ($12 per month).

Grammarly does not store, sell, or share documents with other parties.

There is a support page with tips, tutorials, and FAQs, and it is possible to submit a question via a form. However, there is no live support.

Discover Grammarly’s plagiarism checker

Plagiarism detector

  • Does not store or sell your document
  • Difficult to find the plagiarized source in the report
  • Same highlight colors for different sources
  • Technical difficulties generating the report, and no live support

This tool had difficulty uploading the document for each round of testing (for the first round, it took over six hours to generate a report). It seems that Plagiarism Detector was unable to adequately process a document of this size, even though the document did not exceed their word limit of 25,000.

This tool was mostly only able to find partial matches, attributing individual sentences to one or more sources, rather than the entire section.

In the downloadable report, the format of the text is lost, making it hard to read. The list of sources is also difficult to cross-reference with the text above because the same colors are used for different sources.

Plagiarism Detector offers a rewrite tool to help resolve similarities, but the quality of this tool is questionable, and it does not help with the citation issues. You should resolve plagiarism by citing the relevant source, not by attempting to rewrite the text to disguise it.

Plagiarism Detector does not store or sell uploaded documents. There is no live support, but the website does offer a help request form.

Copyleaks

  • Text layout is kept intact in the online tool
  • Difficult to read reports
  • Performed poorly with academic sources
  • Unclear data protection policy

Copyleaks performed relatively poorly with all source types. It lists multiple possible sources for flagged sentences. However, it was sometimes able to attribute an entire source block to the correct source.

The report distinguishes between text that is “identical” to a source, text that contains “minor changes,” and text that is “paraphrased.” However, its judgment is sometimes wrong.

The site report and downloadable report differed (the downloaded report flagged content that was not flagged on the site report). On the website report, the source information function did not always work correctly, so it was sometimes impossible to check the accuracy of the attributions.

The reports were also difficult to read, as they use the same color highlights for all sources. While the source formatting is maintained in the online tool, it is altered in the downloadable report.

Copyleaks claim that they “will never steal your work.” To permanently remove uploaded content from their database, users must contact customer support. The website has a chat option and a contact form.

Discover Copyleaks’ plagiarism checker

Smodin

  • Site has a citation generator
  • Very low word limit
  • Report is difficult to read
  • Scans individual sentences rather than full texts

Smodin performed relatively poorly in all rounds of testing. While it got some sources correct, it struggled to get full matches and frequently attributed the same text to multiple different sources. It did particularly poorly with scholarly sources.

The tool has a very low limit of 2,000 words per scan.

Both the online report and the downloadable PDF report are difficult to read. The downloadable report displays the uploaded document, but it doesn’t highlight the text that it flags as plagiarized. Instead, below this, it includes the individual parts of the text that it recognizes as plagiarism.

However, it is difficult to read as the same text is repeated over and over again if multiple sources were found for it. The sources also do not seem to be in a logical order.

Their data protection policy suggests they can/might sell or repurpose uploaded content. There is no live support, but there is a contact form on the site.

Discover Smodin’s plagiarism checker

Compilatio

  • You can use your credits for multiple documents
  • Scans against other documents you have uploaded
  • Doesn’t highlight the plagiarized parts in the text
  • Hard to review and resolve instances of plagiarism

Compilatio was able to find a few of the plagiarized sources, but it struggled if the source text had been moderately or heavily edited. However, when it was able to identify a source, it was often correct.

It was not possible to determine how accurately Compilatio could match the source to a plagiarized source text, since the plagiarized parts were not highlighted. Instead, the report only shows the general area that matches the source. This may limit its helpfulness to users, since it’s hard to review and resolve potential instances of plagiarism.

As the report does not highlight the flagged text, it does not provide a good overview of the potential issues. Additionally, you cannot work in the tool, so it’s not possible to exclude similarities from the report.

The tool scans the text against other documents you have uploaded, which can help to avoid self-plagiarism.

Users can buy packages for 5,000 words for €3.99 (no $ value is available on the site), 25,000 words for €14.99, or 50,000 words for €24.99. These credits can be used for multiple documents and are valid for 12 months after purchase.

Compilatio does not share or sell submitted documents, and the documents are not used as comparison material for other users.

There is no live support available, but they do provide a helpdesk with FAQs and a request form.

Writer plagiarism checker

  • Part of a tool with many other useful functions
  • Allows you to edit in the tool
  • Text format is not altered
  • Doesn’t find much plagiarism
  • Doesn’t provide a downloadable report

Quality of matches 

This tool found very little plagiarism. It struggled particularly with scholarly sources like dissertations and academic journals.

It scans sentence by sentence, rather than whole paragraphs. As a result, the plagiarized text is often attributed to multiple sources, rather than just one.

The plagiarism checker function is part of a larger language tool that provides grammar and spelling checks. As the tool doesn’t display an overall plagiarism percentage, we couldn’t apply our normal testing methodology. 

The tool has a nice, clean design and was relatively easy to use. The format of the text remains intact, and you can work directly in the tool. However, it doesn’t provide a downloadable report, so you must work solely on the website.

Writer claims that its tool is secure and safe to use and that it won’t share your information with anybody. A detailed security policy is described on a separate page.

They provide a contact number and email address on the site, but no live support.

Plagiarism can be detected by your professor or readers if the tone, formatting, or style of your text is different in different parts of your paper, or if they’re familiar with the plagiarized source.

Many universities also use plagiarism detection software like Turnitin’s, which compares your text to a large database of other sources, flagging any similarities that come up.

It can be easier than you think to commit plagiarism by accident. Consider using a plagiarism checker prior to submitting your paper to ensure you haven’t missed any citations.

The accuracy depends on the plagiarism checker you use. Per our in-depth research , Scribbr is the most accurate plagiarism checker. Many free plagiarism checkers fail to detect all plagiarism or falsely flag text as plagiarism.

Plagiarism checkers work by using advanced database software to scan for matches between your text and existing texts. Their accuracy is determined by two factors: the algorithm (which recognizes the plagiarism) and the size of the database (with which your document is compared).

Yes, Scribbr offers a limited free version of its plagiarism checker in partnership with Turnitin. It uses Turnitin’s industry-leading plagiarism detection technology and has access to most content databases.

💯 12 Online Plagiarism Checkers

🔗 references, 🤔 why use a plagiarism checker.

The issues of plagiarism and academic dishonesty become more and more relevant each year. According to some research , 92% of surveyed students stated that they had or knew someone who had cheated .

So, why does this happen?

The researchers have shed light on this phenomenon, and here are some of their statistics:

  • 92% of those who plagiarized stated that they did so because they wanted better grades.
  • 83% said that they cheated because of procrastination.
  • 75% of respondents pointed out that they did not have enough time to finish their assignments.
  • 33% have attempted to cheat due to their overloaded class schedule.
  • 58% of the surveyed have plagiarized because they lacked an understanding of the subject.
  • 50% had little or no interest in the subject.
  • 25% of participants believe that anyone can cheat without any consequences.
  • 17% of the interviewees cheated because of peer pressure.
  • Another 17% think that it does not matter to the professor if their paper is plagiarized.

After taking all of these numbers into account, it is evident that a significant percentage of students commit acts of plagiarism for several main reasons. Among them are poor time management, concern for academic performance, and peer pressure.

Now that you know the causes of plagiarism, it will be beneficial to examine its different types. Generally, these can be divided into two groups: unintentional and intentional.

Intentional Plagiarism

When it comes to intentional plagiarism, it doesn’t necessarily mean that your paper copies the full document written by someone else. This is only one example of cheating out of many others.

Unintentional Plagiarism

Meanwhile, unintentional plagiarism may refer to:

  • Forgetting to cite a source when describing something that is not common knowledge.
  • Not citing information that you have paraphrased or summarized.
  • Failing to use a proper citation style when documenting sources.
  • Misquoting an author, even if it is appropriately cited in the paper.

When composing your paper, it is important to stay vigilant. This is why it is handy to utilize the help of our plagiarism checker (2000 words). Free detection software is a quick and easy way to confirm your paper’s originality.

🔍 How to Check for Plagiarism

As you work on your paper, you may start to ask yourself: How can I avoid plagiarism altogether?

Below, we have prepared some tips that will help you write a 100% original essay:

  • Regulate your time. As mentioned earlier, procrastination and a full class schedule may lead to plagiarism. To stay on top of everything, don’t put off urgent tasks until tomorrow. Read up on time management techniques and figure out an efficient study method that works for you.
  • Cite while you write. Get in the habit of citing sources in full as you write your paper. Firstly, doing this will save you plenty of time for putting together a bibliography. Second, it will significantly decrease the risk of an improper citation.
  • Use only trusted sources. There are a lot of websites with questionable content. Even documents that seem scholarly at first could turn out to be another student’s paper. Ascertain that you understand the source and the ideas that it is trying to convey.
  • Understand the difference between various citation styles. An improper citation may result in a penalty for plagiarism. So, make sure you rely on a high-quality reference guide and implement the correct style. Don’t forget to add quotation marks when using unchanged phrasing from the source.
  • Use plagiarism scanners before you submit your paper. Even if you wrote your piece from scratch, we still advise you to double-check it. From time to time, you might unintentionally “borrow” a couple of phrases that appear in other works. Despite it being an accident, your professor might penalize your paper. To avoid this, you can use one of the online free plagiarism detectors.

Perhaps our free plagiarism checker (2000 words & more) wasn’t exactly what you were looking for. If you find yourself in need of a tool with slightly different features, this section is for you!

Below, we have prepared a list of 12 online plagiarism scanners , both chargeable and free. They will allow you to avoid similarities with other works on the Internet.

Scribbr is a plagiarism checker powered by Turnitin, a plagiarism-detection system used by most universities. Therefore, it is an excellent choice for those seeking access to Turnitin but not being able to get it. Scribbr offers a free version, but it only allows you to see whether your paper contains potential plagiarism. To see a full report, you have to go premium, which starts from $19.95 per document.

2. Grammarly

Grammarly is famous for its superior grammar-checking software. However, with a paid version, you’ll also get access to its plagiarism detector. It can check your paper against billions of web pages, but its detection doesn’t cover gated and academic content. It also fails to identify rephrased content.

3. PlagScan

PlagScan is an outstanding plagiarism detection tool that is useful for students and writers alike. The website compares your paper against web sources, journals, and internal repositories. It doesn’t offer a free plan, but it allows you to check your first 2,000 words without charge during your free trial.

4. PaperRater

PaperRater is another plagiarism detection service. It operates as freemium software and provides you with a free report. The chargeable version allows you to get a printed summary of your results that contains more detailed information. This program is also integrated with a proofreader and supports various file types for upload.

5. Plagiarisma

Plagiarisma is a simple and free tool for students to use. It works with Google, Yahoo, Bing, and Scholar databases. Don’t forget to register to check your paper!

6. Dupli Checker

At first glance, Dupli Checker is similar to those mentioned above. However, this website has extra features, such as a text spinner, spell checker, word counter, etc. Of course, it also detects plagiarism and provides you with stats, links to plagiarized URLs, and highlights of related phrases. Did we mention that it’s free?

Viper , also known as ScanMyEssay, is a plagiarism detector supporting 56 languages. It checks your content against over 10 billion sources and can scan multiple files at once. Viper offers a free trial, allowing you to check one document of up to 5,000 words. It’s a good option for students who need to scan their papers for plagiarism occasionally.

8. PlagAware

PlagAware offers high-quality plagiarism detection and checks your papers against over 70 billion sources! It has a free plan that allows you to scan 10 pages per month. Moreover, if you choose a premium plan, you pay only for the first check of every document, while subsequent scans of the revised versions are free.

9. Copyscape

Copyscape is a plagiarism detector that can check your paper against online sources and web pages. It doesn’t check your content against academic databases, books, scholarly journals, and offline sources. So, it’s suitable for online content creators and website owners, while students seeking to check academic writing should opt for something else.

10. Copyleaks

Copyleaks offers both free and paid accounts to its users. In both cases, you have to register to use this service. If you have a free account, you can upload up to 2,500 words per month and use two checks. You will also see the history of your previous plagiarism scans.

11. Quetext

Quetext is a user-friendly plagiarism checker that allows you to edit text directly within the tool and has a useful feature — a citation assistant. However, you can check only 500 words with their free plan. After exhausting this limit, you have to go premium. It can also fail to identify plagiarism from scholarly sources like student dissertations or journal articles.

12. SmallSEOTools

The last paper plagiarism checker tool in our list, SmallSEOTools , allows you to check up to 1000 words per search for free. The amazing thing about this tool is that it’s available in English, Chinese, Russian, Italian, French, Portuguese, Spanish, German, and Japanese languages.

Remember – for students, getting caught plagiarizing may mean a failing grade, suspension, or even expulsion. For professionals, the stakes are even higher. Therefore, make sure to use our plagiarism checker for 100% accurate results!

Best Plagiarism Checker for Research Papers and Thesis – Free and Paid

If you are writing scientific papers or academic thesis, one of the most critical aspect of your work is avoiding and reducing plagiarism from your papers. In this post we will break down the most useful plagiarism checker for research work and journals. 

The recommendations in this article have a data-base of thousands of papers from medical, engineering and other domains and AI capabilities to offer plagiarism reports.

Recommendation Plagiarism Detectors for Research

  • Turnitin (Only registered students and researchers can use it. Not available for public)
  • Plagiarism Checker X ( Available in 7 languages including German; Used by top Universities and companies )
  • Grammarly ( Grammar checker and Plagiarism detection tool; Now available on Mac and Windows )
  • ProWritingAid ( Plagiarism and Grammar error correction; Loved by Millions of Authors, Writers and academicians )

Hunting plagiarism in research papers is more daunting than a personal website or a blog.

Where you can have a fair excuse and the luxury of <blockquote> , which help other search engines to know that you have copied online, you don't have such an option while working on your thesis. Here we are writing about the best software tools to prevent plagiarism in research work.

Plagiarism is unacknowledged copying or an attempt to misattribute original authorship, whether of ideas, text or results.

source: https://www.nature.com/authors/policies/plagiarism.html

There can be multiple ways to plagiarise your hard-worked content. We have already talked a lot about accidental plagiarism and ways to protect it in our previous articles.

You can also test your knowledge by taking a simple plagiarism quiz which will help you to understand and avoid plagiarism in a better manner.

Other is, as you know, intentionally. No matter, how are you messing up with the act, it will be equally offensive.

Steps to Avoid Plagiarism in Research Work

  • The best way to stay original is: staying original. Don't get me wrong. All I want to say is, think with your own imagination. Paraphrasing is actually detectable if it is not done properly. Also, if you are doing it, you should not forget to add an in-text citation properly.
  • Another important thing is to keep track of your work from the very beginning of your work. You can use cloud services like Evernote and Pocket to keep track of URLs, PDFs, Blogs, Websites, and Other Works.
  • Unorganized papers often lead to plagiarism. You should be very careful while copying word-by-word. You can use "Quotes" to highlight the part which is copied with a source.
  • Never trust Free services. Writing about the thousandth time, Do not use free tools. They will only lead you to false results and the risk of getting plagiarized with your own work. Paying someone to check your work on Turnitin will only lend you to hazard.
  • If Your paper is an assignment, always do everything as instructed by the professor.

Best Plagiarism Checker Tools for Research and Journals

Without any doubt, Turnitin is a good tool to detect a similarity between the strings, whether it is a research work or an assignment. It has a huge database of research work and it is capable to find similarity in your content with the previous works.

A common myth about Turnitin is that it is a perfect tool. It is Not! Also, it is not a deciding tool   that you have actually plagiarized. Instead, it shows results to your professors for possible similarity among previously submitted work. That depends on the setting teachers are using. Only the examiner and you (human) can judge whether you have plagiarized or not.

Plagiarism Checker X

Plagiarism Checker X is the best alternative to Turnitin for many reasons. It provides some of the coolest features for students and professors. Some of them are bulk uploading, side-by-side comparison, automatic citation and multiple language support. It is the only tool on the planet which provides offline check after two consecutive checks.

You can play with the free version to test the waters before going for a premium one which is also available for less than $40 for a lifetime. It is being used by several universities and top companies as their standard tool.

PlagiarismcheckerX supports All Windows Platforms and you will be required to download .exe file to work with this plagiarism checker for academics.

Grammarly is one of the biggest companies working closely in education and industry. Hundreds of companies, schools, and universities are using Grammarly for proofreading, plagiarism checking, and learning English Grammar. They have a great database and constantly learning algorithms that are becoming better with time.

Not to forget, Grammarly is a safe tool (forget rumors) and they don't sell your data to anybody. With the provided browser extension, Android support, and native applications, it gives much power to you as an academician.

It supports macOS, Android, iOS, Windows, Google docs, and have a web application.

Plagiarisma.net

After a considerable amount of research, I came to the only Free tool which is safe to be used for research work. It uses Google Scholar search results to detect similarities in your content. Plagiarisma.net is able to detect more than 10 billion (as they claim) search engine results and it can be used from their website as well via their Windows application. But take this advice with a grain of salt.

Note that Plagiarisma only supports Windows operating systems.

ProWritingAid

Loved by some of the best selling writers, ProWritingAid is a decent grammar editor and contextual writing editor. In the premium version of the software, which is available on Apple devices, Windows, Google Doc, and Scrivener, has an integrated plagiarism checker.

ProWritingAid comes with fair pricing and great features, it can be on your radar if you are looking for a plagiarism checker for avoiding accidental pitfalls.

MOSS - Plagiarism checker for Code

(Measure of Software Similarity) or popularly known as MOSS is a tool that is very specific to the task of finding copied content for programmers. It is the (perhaps) best possible plagiarism checker ever created to detect plagiarism in software codes and programs. It was created in the Stanford labs in 1994. Since its inception, it is being used in several classrooms and research works to detect similarity in codes.

Bottom Line

The best way to protect your research is to keep it confidential. The above tools are tested and provide at most security to your data. Plagiarism can ruin your career and is unbearably frustrating. I hope the above tools will help you to write better assignments and get better grades.

Best wishes.

Our expert review:

Reasons to buy

Reasons to avoid.

Unicheck provides a high-quality service by combining high-end technology with smart design, and it clearly works – more than 1,000 academic institutions worldwide use this app.

This tool has access to more than 91 billion pages and library files, so you can be sure that it’s checking every source available for plagiarized material. And don’t worry about being overwhelmed with data once the app has searched the web, either: results appear in a straightforward interface that displays sources and color-codes copy, and each piece has a plagiarism score that’s adjusted as you edit the article.

Unicheck’s 99.9% system uptime means you’ll be able to check for plagiarism when you need it, and its authorized, encrypted accounts deliver high-level security for users.

The versatility and power continue elsewhere. A personal dashboard is perfect for managing loads of sources or articles, and Unicheck integrates with Office 365, Google Docs, and Chrome, so you can check for plagiarism without ever leaving those apps. It’s got an accessible API, too, so the tool integrates with other services.

Unicheck doesn’t have to be expensive, either. Its Personal package costs as little as $5 and scales up depending on how many pages you’d like to check, and there are more extensive packages for educational establishments and businesses. No matter which one you choose, though, it’s clear that Unicheck remains one of the best plagiarism checkers on the market.

Scribbr website screenshot

Scribbr provides a plagiarism checker that is part of a wider suite of tools that include an academic proofreading module and an APA reference generator. Unsurprisingly, the products on offer here will appeal to students and academics, and the site helps craft dissertations, essays, and thesis documents.

The plagiarism checker does a stellar job. Scribbr partners with Turnitin, which can detect everything from precise word and phrase matches to language where synonyms have been to used, and Scribbr checks writing against a database that covers 91 billion web pages and 69 million publications. Impressively, you can upload old assignments or referenced works to compare, too – perfect if you want to check your writing against something that won’t be in Scribbr’s database.

Beyond plagiarism, Scribbr offers expert editors who can edit essays, thesis documents, funding proposals, and literary reviews – it’s ideal for making sure that your academic work is top-notch, no matter the subject. Scribbr also provides a generator and checker for APA citations so you can be sure that no-one will question your sources.

Scibbr’s plagiarism checking service ranges in price from around $20 / £14 / AU$27  to $40 / £32 / AU$63, depending on the length of the document, and you’ll get your checked document within ten minutes.

The lack of dashboard and security features, when compared to other services, means that Scribbr isn’t suitable for large enterprises. But if you’re a student or academic, it’s well-designed and potentially invaluable.

Grammarly website screenshot

3. Grammarly

Grammarly is one of the world’s most popular writing assistants, and no wonder: it does a fantastic job of checking written work for linguistic accuracy alongside its readability and tone. It’s also available as an app, as a plug-in for most word processing tools and as a browser extension.

It works in email clients , on social networks, and even in Slack and Discord too – so you’ll always be able to rely on this tool.

Grammarly has a great plagiarism checker, too. It uses the academic papers in ProQuest’s database and more than 16 billion web page sources to check for plagiarized text, and if the app detects copied language or phrases then you’ll get an alert in your document.

Grammarly’s plagiarism checker is free to use, but we don’t recommend this option – it will tell you if you’ve plagiarized, but it won’t show you where.

Instead, we recommend signing up to Grammarly’s paid tiers – you get its grammar, spelling, and punctuation tools alongside its clarity, engagement, tone, and plagiarism detection. Grammarly is one of the best linguistic tools on the web.

Grammarly’s prices start at around $11 / £10 / AU$16 per month.

PlagScan website screenshot

4. PlagScan

PlagScan is a robust plagiarism deterrent focused on the academic circle. While used by many other fields as well, the features that make PlagScan stand apart among other plagiarism tools seem geared in this direction.

Pricing is pretty reasonable, with plans per word for individuals and some business plans as well. Prices can vary from $6 - $50 or more on average. On the higher level plans, there are advanced features including API abilities, support and more. There is also the ability to create more detailed reporting and integrate with tools you are already using.

Compared to other tools, PlagScan is pretty good about picking up possibilities, albeit sometimes too good. There are the occasional mistake, as in it notifies of a plagiarized item that is not actually there, however all around this tool is fairly accurate.

PlagScan itself even will say that the only true way to see if something is plagiarized is to utilize human support, confirming what PlagScan finds. But, without this tool, you would take much longer to find these similarities!

Lastly, there are easy color-coding highlights that help show what kind of infraction is found in offending pieces of writing.

Plagramme website screenshot

5. Plagramme

Plagramme has a range of features that goes beyond what you’ll find with many other anti-plagiarism tools. It doesn’t just check billions of sources – it highlights your article with plagiarism risks, potentially paraphrased sections, poor citations, and textual similarities. Combine this with a straightforward scoring system, and you’ll be able to quickly see how much of any article is at risk.

This system is multilingual, so it can detect issues in different languages, and Plagramme also offers an authenticity service where its own editors check and fix documents manually. This does cost more, but it’s ideal if you have an important document that needs perfection. And, at the other end of the scale, there’s a free plagiarism checker – although this performs a quick check without the in-depth reporting or database access of the full product.

Once you’ve signed up for an account then you’ll be able to see Plagramme’s full range of services. It’ll cost a few dollars to skip the queue and a few more to get an in-depth report, and you can buy credits that work on any of Plagramme’s services.

This credit-based system and the emphasis on individual documents mean that Plagramme may not suit large organizations, but it’s well-suited to individuals and small businesses. 

Quetext website screenshot

Quetext has plagiarism detection algorithms that use a system called DeepSearch, which relies on word placement, deep learning, and contextual analysis to deliver smarter and more sensible results when you scan a document.

This tool can check for plagiarism in academic documents, news articles, blog posts, and webpages, so it’s versatile. It’s easy to use too: potentially plagiarized words or phrases are highlighted using a color-coded system with bolder shades for more significant issues. Side-by-side displays mean you can see exactly where the plagiarized text originated. And, at the end of the process, content gets a score so you can see how it’s performed.

Quetext also prizes itself on its straightforward pricing. If you pay for the basic package that allows you to check 100,000 words. The Plus package doubles the cost and increases the word allowance to 250,000, and there’s an Organization option that’s ideal for companies. Impressively, every product includes every feature – the good stuff is never held back for those who are willing to pay more.

Plagiarism checker FAQs

What is plagiarism.

Simply put, plagiarism is cheating. it refers to the act of copying one’s content and passing it off as your own. Grabbing someone’s photo and using it without permission and/or proper credits can be considered an act of plagiarism. Taking some text from a source and using it on your website without proper citation is also an act of plagiarism. 

In college, getting caught plagiarizing can lead to expulsion and can ultimately end any plans you have for your future. Stealing content for your own blog is not considered a form of flattery either, nor is it legal. Copying content for your own website can get you reported and your website taken down. 

What are the common types of plagiarism?

There are a couple of ways to commit plagiarism, but here are the five most common types:

1. Verbatim plagiarism - This is a common crime wherein a text or content is copied exactly as it is written without any form of credit or citation. 

2. Mosaic plagiarism - This type of plagiarism involves copying content from different websites or sources and combining them without any form of credit or citation. 

3. Global plagiarism - This means deliberately claiming someone else’s entire work as your own. 

4. Self plagiarism - This is when you resubmit your own work when you’ve already used it. It’s also known as auto plagiarism.

5. Accidental plagiarism - This occurs when you unintentionally commit plagiarism by paraphrasing a content and failing to cite or add credits. 

As content is a vital ingredient in SEO ranking which is always a neck to neck competition, websites are usually trying to come up with more content than they likely would have expected to be needing. A team of writers usually solve the problem, but it’s also where a new problem arises - monitoring the content.

Whether it’s an intentional copying of content or a missed citation, quote or credit, plagiarism isn’t as easy to detect if you’re dealing with tons of articles to check. The good news is that there are resources available - plagiarism checkers - that you can utilize to make it an easier task.

How to choose the best plagiarism checkers for you?

When choosing the best plagiarism checker for yourself, you'll want to start with assessing whether you want a standalone plagiarism checker or something with more features to improve writing. 

You'll want to consider the tool's user interface and learning curve. The simpler it is to operate, the more efficient you can be with your checking. 

If you're working alone, you may do well with a certain type of plagiarism checker, but the same tool may not be suitable for larger organizations. 

You'll also want to take the plagiarism tool's pricing into consideration, check how many users it can support, and analyze how well it integrates with third-party apps. 

How we test the best plagiarism checkers

To test the best plagiarism checkers, we first evaluated whether the tools are standalone plagiarism checkers or if they offer a suite of language improvement tools. 

We analyzed how large their content database is, whether there's citation checking, and what third-party apps they integrate with.

We assessed the tools' user interface and learning curve, and the kind of algorithm they were using to effectively spot plagiarism. We also considered their pricing plans, the number of users supported on each plan, and what type of client they'd be ideal for, among other things.

Check for unintentional plagiarism

Easily check your paper for missing citations and accidental plagiarism with the EasyBib plagiarism checker. The EasyBib plagiarism checker:

  • Scans your paper against billions of sources.
  • Identifies text that may be flagged for plagiarism.
  • Provides you with a plagiarism score.

You can submit your paper at any hour of the day and quickly receive a plagiarism report.

What is the EasyBib plagiarism checker? 

Most basic plagiarism checkers review your work and calculate a percentage, meaning how much of your writing is indicative of original work. But, the EasyBib plagiarism checker goes way beyond a simple percentage. Any text that could be categorized as potential plagiarism is highlighted, allowing you time to review each warning and determine how to adjust it or how to cite it correctly.

You’ll even see the sources against which your writing is compared and the actual word for word breakdown. If you determine that a warning is unnecessary, you can waive the plagiarism check suggestion.

Plagiarism is unethical because it doesn’t credit those who created the original work; it violates intellectual property and serves to benefit the perpetrator. It is a severe enough academic offense, that many faculty members use their own plagiarism checking tool for their students’ work. With the EasyBib Plagiarism checker, you can stay one step ahead of your professors and catch citation mistakes and accidental plagiarism before you submit your work for grading.

best plagiarism checker for research papers free

Why use a plagiarism checker? 

Imagine – it’s finals week and the final research paper of the semester is due in two days. You, being quite familiar with this high-stakes situation, hit the books, and pull together a ten-page, last-minute masterpiece using articles and materials from dozens of different sources.

However, in those late, coffee-fueled hours, are you fully confident that you correctly cited all the different sources you used? Are you sure you didn’t accidentally forget any? Are you confident that your teacher’s plagiarism tool will give your paper a 0% plagiarism score?

That’s where the EasyBib plagiarism checker comes in to save the day. One quick check can help you address all the above questions and put your mind at ease.

What exactly is plagiarism? 

Plagiarism has a number of possible definitions; it involves more than just copying someone else’s work. Improper citing, patchworking, and paraphrasing could all lead to plagiarism in one of your college assignments. Below are some common examples of accidental plagiarism that commonly occur.

Quoting or paraphrasing without citations

Not including in-text citations is another common type of accidental plagiarism. Quoting is taking verbatim text from a source. Paraphrasing is when you’re using another source to take the same idea but put it in your own words. In both cases, it’s important to always cite where those ideas are coming from. The EasyBib plagiarism checker can help alert you to when you need to accurately cite the sources you used.

Patchwork plagiarism

When writing a paper, you’re often sifting through multiple sources and tabs from different search engines. It’s easy to accidentally string together pieces of sentences and phrases into your own paragraphs. You may change a few words here and there, but it’s similar to the original text. Even though it’s accidental, it is still considered plagiarism. It’s important to clearly state when you’re using someone else’s words and work.

Improper citations

Depending on the class, professor, subject, or teacher, there are multiple correct citation styles and preferences. Some examples of common style guides that are followed for citations include MLA, APA, and Chicago style. When citing resources, it’s important to cite them accurately. Incorrect citations could make it impossible for a reader to track down a source and it’s considered plagiarism. There are EasyBib citation tools to help you do this.

Don’t fall victim to plagiarism pitfalls. Most of the time, you don’t even mean to commit plagiarism; rather, you’ve read so many sources from different search engines that it gets difficult to determine an original thought or well-stated fact versus someone else’s work. Or worse, you assume a statement is common knowledge, when in fact, it should be attributed to another author.

When in doubt, cite your source!

Time for a quick plagiarism quiz! 

Which of the following requires a citation?

  • A chart or graph from another source
  • A paraphrase of an original source
  • Several sources’ ideas summarized into your own paragraph
  • A direct quote
  • All of the above

If you guessed option E than you’d be correct. Correct punctuation and citation of another individual’s ideas, quotes, and graphics are a pillar of good academic writing.

What if you copy your own previous writing?

Resubmitting your own original work for another class’s assignment is a form of self-plagiarism, so don’t cut corners in your writing. Draft an original piece for each class or ask your professor if you can incorporate your previous research.

What features are available with the EasyBib plagiarism checker? 

Along with providing warnings and sources for possible plagiarism, the EasyBib  plagiarism checker works alongside the other EasyBib tools, including a grammar checker  and a spell checker . You’ll receive personalized feedback on your thesis and writing structure too!

The  plagiarism checker compares your writing sample with billions of available sources online so that it detects plagiarism at every level. You’ll be notified of which phrases are too similar to current research and literature, prompting a possible rewrite or additional citation. You’ll also get feedback on your paper’s inconsistencies, such as changes in text, formatting, or style. These small details could suggest possible plagiarism within your assignment.

And speaking of citations, there are also  EasyBib citation tools  available. They help you quickly build your bibliography and avoid accidental plagiarism. Make sure you know which citation format your professor prefers!

Great! How do I start? 

Simply copy and paste or upload your essay into the checker at the top of this page. You’ll receive the first five grammar suggestions for free! To try the plagiarism checker for free, start your EasyBib Plus three-day free trial.* If you love the product and decide to opt for premium services, you’ll have access to unlimited writing suggestions and personalized feedback.

The EasyBib plagiarism checker is conveniently available 24 hours a day and seven days a week. You can cancel anytime.  Check your paper for free today!.

According to the Oxford Dictionary Plagiarism is:

“The practice of taking someone else's work or ideas and passing them off as one's own”

In precise words, plagiarism is an act of fraud. It involves both stealing someone else's artwork and lying approximately it in a while.

How you can avoid plagiarizing

ILLUSTRATION

Know the different types of plagiarism

There are several types of plagiarism, and it’s essential to understand the differences to avoid making these mistakes and prevent plagiarism in the classroom.

  • Direct plagiarism: Using someone else’s exact words and using them as your own with no credit to the source. Eliminating portions of the text still qualifies as direct plagiarism.
  • Patchwork plagiarism: Creating new text by combining exact phrases or sentences from multiple sources without acknowledging the original authors or sources.
  • Self-plagiarism: Attempting to reuse or recycle your previous work and claiming it as a new piece of work without mentioning the source of original publication.
  • Source-based plagiarism: Producing false sources within your writing or omitting one or more references from citations.

Cite your sources

Students often think of citations as a simple means of acknowledging another author's work. While this is their main purpose, there are other benefits as well.

Source citations also show readers where to go to learn more. By providing context around the citation in student papers, such as the source medium and when it was published, readers can locate the information more easily. Giving too little source information or improperly formatting it can result in unintentional plagiarism. These mistakes also make it difficult for readers to locate the original source and verify information.

Quetext's citation generator makes it easy for students to accurately cite their sources without slowing down their writing process. Once a user inputs the text, the software identifies the passages that require a citation and subsequently generates it in the style required — APA, MLA, or Chicago.

Always use a plagiarism checker

The best way to avoid severe plagiarism consequences is to use a plagiarism checker. Often, plagiarism is unintentional and results from poor paraphrasing of material found online. Using a plagiarism checker, the student can avoid accusations of any kind of plagiarism and benefit from a close review of the original material.

Quetext's plagiarism checker provides a speedy, easy process for students to receive accurate results, identifying areas of concern and providing on-page solutions.

Plagiarism Checker for Students FAQ

What are the consequences if a student is caught plagiarizing.

The consequences of plagiarism vary according to the student’s academic institution and grade level. For example, a middle school student who plagiarizes within an essay may receive a stern warning and additional instruction related to the process of citing sources or summarizing one’s thoughts.

However, students in higher education institutions guilty of plagiarism in academic papers face much steeper repercussions, including, but not limited, to failing grades and disciplinary or legal action. Factors such as the assignment itself, the instructor, and whether or not it is your first offense impact the outcome.

Depending on the severity of the situation, plagiarism can also impact a student’s reputation or future career opportunities.

How does a plagiarism checker help students?

A plagiarism checker helps students be proactive in finding instances of plagiarism before an assignment is completed and turned in with no way to correct the errors.

In addition, by identifying the potential conflicts early, students can conduct further research to find alternative sources to understand the material better and revise or rewrite the offending passages.

Plagiarism checkers also help students learn innovative writing techniques, improve their writing skills through better research and experience in summarizing ideas, and preserve academic integrity.

Do teachers use plagiarism checkers?

Many teachers use plagiarism checkers to ensure a student’s submission is 100% original work. With the rise of easy-to-use tools like Quetext, checking for authenticity and text matches is a quick and affordable process to scan millions of online data sources.

Using plagiarism checkers also allows teachers to educate their students on the importance of citing sources and the ethical responsibilities of research and opinion writing.

Plagiarism has always been a source of concern for teachers, but until now, options for manual detection have limited their opportunities to identify the problem efficiently. However, the evolution of technology in this area has made the tools more accessible than ever.

How do teachers check a paper for plagiarism?

Teachers are skilled at detecting plagiarism, especially those who have been teaching for a significant period or who teach in the areas of English or Literature. Some teachers use a simple technique of entering a sentence into a search engine to find instances of duplicate text on web pages.

However, this manner of plagiarism detection is manually intensive and dependent upon unreliable algorithms. Some may use their writer’s intuition by identifying anomalies in sentence structure, inconsistencies in vocabulary or grammar, or a combination of all of these.

Others use more sophisticated and robust plagiarism detection software, like Quetext. Quetext can scour millions of sites using DeepSearch™ technology to identify plagiarism in seconds. These tools also enable instructors to work with students to improve their writing and avoid repeating the same mistakes in the future.

Can students get in trouble for accidental plagiarism?

Yes, students can be penalized for plagiarism, even if it was an accident. Unfortunately, instructors have no way of knowing the intent behind plagiarism. Depending on the type of plagiarism, instructors may allow leeway for students to learn from their mistakes and correct the work without the threat of severe consequences.

However, repeat offenders are less likely to receive this flexibility and may face steeper penalties. Additionally, instructors of college-level courses with clear plagiarism guidelines and policies may be less inclined to let students off the hook and instead enforce severe consequences.

Is there a free plagiarism checker for students?

Yes! Quetext offers both a free and a paid subscription for students to seamlessly verify their writing. Quetext goes beyond traditional plagiarism checkers to provide students with advanced technology that puts content through three layers of evaluation in just a matter of seconds. This level of insight enables students to understand the degree to which the text has been plagiarized and decide whether to rewrite the text or use the citation assistant to cite sources.

Quetext also offers a detailed report students can use to document their editing efforts and present as proof of a plagiarism-free, 100% original content document.

Quetext's plagiarism tool also offers flexible pricing for its Pro features which facilitates the citation of online sources, attributions, and real-time feedback for writing improvement.

How can a student check for plagiarism?

Anyone can enter the text from a research paper into a search engine and find potential matches that identify instances of plagiarized content or duplicate content. However, this method is largely ineffective and does not identify every area of concern.

Students can use Quetext's free online plagiarism checker by creating an account, copying and pasting the text in question into the plagiarism checker, and receiving a comprehensive analysis with color-coded feedback, a plagiarism percentage score, and options for editing the text.

Quetext is one of the best plagiarism checkers available with high-quality insights and accurate results.

Quick Verdict – Is Scribbr Worth the Money?

After putting Scribbr through its paces, it’s worth checking out! 

If you’re serious about producing unique, plagiarism-free content, Scribbr’s thoroughness and accuracy are invaluable. Scribbr is remarkably thorough, catching even the sneakiest of similarities. Plus, it’s incredibly user-friendly, even if you’re not a tech whiz.

You may think that such a robust tool comes with a decent price tag. Still, Scribbr offers excellent value, especially considering the potential cost of academic or professional repercussions from unaddressed plagiarism. Its pricing structure is transparent and adaptable to different needs, making it a worthwhile investment for anyone serious about content integrity.

While Scribbr is highly effective, it could be better. The tool can occasionally miss very small matches or flag common phrases as potential plagiarism, which requires manual review. However, these minor issues don’t detract from its overall efficacy. Another hiccup I encountered was a slightly longer processing time for larger documents.

Are you ready to take your content’s authenticity to the next level? Try Scribbr today and experience firsthand how it can safeguard your work against plagiarism while enhancing your writing quality!

Don’t just take my word for it; try it out and see the difference it makes!

Who is Scribbr for?

You’ll love scribbr if:.

  • You’re an academic professional or student who requires thorough checking to safeguard and ensure the credibility of your scholarly work.
  • You’re a content manager or creator looking to maintain the uniqueness of your website or blog content, which is critical for standing out in competitive digital spaces.
  • You’re an educator or tutor who regularly checks large volumes of academic work for plagiarism and insists on maintaining a high standard of academic honesty among students.

You won’t love Scribbr if:

  • You need a tool primarily for copyediting or proofreading. Scribbr’s strengths lie in its plagiarism detector, not in-depth language editing.
  • You’re looking for a one-off solution. If you don’t often need plagiarism-checking services, the cost and depth of Scribbr’s features might not be the most practical choice.
  • You work with extremely time-sensitive projects. While Scribbr is efficient, the processing time for very large documents might not be sufficient for last-minute assignments.

What is Scribbr?

Scribbr is a comprehensive plagiarism checker designed to safeguard the authenticity of your written work. Its primary function is to scan your text against a vast database of sources, including websites, academic journals, and books, to identify any instances of potential plagiarism.

What is the key benefit of having Scribbr?

The key benefit of using Scribbr lies in its meticulousness. Unlike most accurate plagiarism checkers, Scribbr goes beyond simply flagging identical matches. It also detects paraphrased content and provides detailed reports highlighting areas that require your attention. 

How does Scribbr work?

Scribbr uses advanced algorithms to scan your text for similarities with published material. It then presents various academic reports, including percentage scores and links to similar sources. These reports are instrumental in helping you understand where your text might need revisions or writing citations.

How is it different from competitors?

Unlike many other plagiarism checkers, Scribbr offers a level of depth in its analysis that is tailored specifically for the academic writing process and professional use. Its database includes both internet pages and scholarly articles and publications, making it exceptionally reliable for high-stakes writing like dissertations and research papers. Scribbr’s feedback system offers constructive advice and explanations rather than just highlighting potential issues.

Reasons I Recommend Scribbr to Everyone

#1) provides thorough and high-quality editing services.

Scribbr plagiarism checker goes above and beyond simple word-for-word matching. It delves deeper into your text, identifying paraphrased content and highlighting potential citation formatting issues. This level of scrutiny gives me the confidence that my work is truly original and well-attributed.

I’ve used Scribbr to review academic papers, blog posts, and website copy. It consistently identified areas where I could improve my writing and ensure its originality in each instance. This has not only saved me from potential embarrassment but also elevated the quality of my work overall.

#2) Scribbr’s plagiarism checker is highly accurate

One of the most remarkable aspects of Scribbr is its accuracy. It’s powered by Turnitin, a leading plagiarism detection software trusted by educational institutions worldwide. This means you’re benefiting from a robust database and sophisticated algorithms that can quickly and accurately identify any instances of plagiarism.

I’ve tested Scribbr against several other plagiarism checkers, and it consistently performed well in terms of accuracy and the depth of its analysis. This level of precision is crucial, especially for students and professionals who rely on the authenticity of their work.

#3) Scribbr supports multiple languages, making it accessible

Unlike some plagiarism checkers that are limited to English, Scribbr supports a wide range of languages. This makes it an invaluable tool for international students, multilingual writers, and anyone who collaborates with individuals from different linguistic backgrounds.

I’ve used it to review documents written in various languages, knowing that it can accurately detect plagiarism regardless of the language used.

What You Might Not Like about Scribbr

#1) professional services are expensive and have limited editor interaction.

If you’re seeking extensive editing or proofreading beyond plagiarism detection, Scribbr’s professional services can be expensive.

While the quality of feedback is generally high, the interaction with the assigned editor is often limited to comments within the document. This might leave you wanting more in-depth discussion or clarification, particularly if you have specific questions or concerns.

I submitted a lengthy academic paper for editing; the feedback was helpful but concise. While it addressed the major issues, I wished I could have engaged in a more direct conversation with the editor to delve into certain nuances or stylistic choices.

#2) AI occasionally produces incorrect results or misses subtle nuance

While Scribbr utilizes advanced algorithms for plagiarism detection, it’s not foolproof. On occasion, the AI might flag passages as potential plagiarism when they are, in fact, original. 

This can be frustrating, especially if you’re confident in your work. Additionally, the tool may miss subtle instances of paraphrasing or plagiarism that a human editor might catch.

This happened when I uploaded a creative writing piece containing unique metaphors and phrasing. Scribbr flagged a few phrases as potentially plagiarized, even though they were entirely my own creations. It took some effort to clarify this with the platform’s support team.

Scribbr Pricing

Scribbr’s pricing structure caters to various needs and budgets. The plagiarism checker operates on a pay-per-check basis, with the cost varying depending on the length of your document. 

Scribbr offers different service levels with corresponding rates for those seeking professional editing or proofreading. Additionally, they have a subscription option for the plagiarism checker, providing unlimited checks within a specified timeframe. You can easily calculate the cost for your specific needs using their online price calculator.

But if you’re still unsure, don’t worry! I’ve explored other alternatives below that might be a better fit for your specific needs.

Scribbr Alternatives

If Scribbr’s pricing is too much for you to stomach right now or you need a different solution, you might like one of these alternatives.

#1) Grammarly

Grammarly is a popular writing assistant offering a free plagiarism checker and comprehensive grammar and spelling correction features. While not as in-depth as Scribbr’s plagiarism detection, Grammarly’s free version can be a great starting point for casual writers and students. It’s particularly beneficial for those who primarily write in English, as its language-specific capabilities are pretty robust.

However, if you require a more comprehensive plagiarism report or wish to check longer documents, you’ll need to upgrade to Grammarly’s premium plan, which does come at an additional cost.

#2) Turnitin

Turnitin is a well-established plagiarism detection software widely used in educational institutions. It powers Scribbr’s Plagiarism Checker and boasts a vast database and rigorous algorithms, making it a highly reliable tool for academic writing.

While Turnitin is less user-friendly than Scribbr and lacks some additional features, like professional editing and citation generation, its strength lies in its unparalleled accuracy and its ability to detect even the most subtle instances of plagiarism.

If academic integrity is your top priority, Turnitin is a worthy contender. However, Scribbr has Turnitin built-in, so you can just go with Scribbr.

#3) QuillBot

QuillBot is a versatile writing tool known for its paraphrasing capabilities. It powers Scribbr’s Paraphraser and Grammer Checker.

QuillBot offers various paraphrasing modes, allowing you to reword sentences and paragraphs while maintaining the original meaning. This can help avoid plagiarism and improve the clarity and flow of your writing.

However, QuillBot’s plagiarism checker is less comprehensive than Scribbr’s Turnitin-powered one. It’s better suited for quick checks and basic paraphrasing rather than in-depth analysis. If you’re primarily focused on paraphrasing and rewriting existing content, QuillBot could be a valuable addition to your toolkit.

What is Plagiarism?

Plagiarism is essentially the “imitation of someone else’s work” without giving them their due credit.

Wikipedia defines plagiarism as the “wrongful appropriation” and “stealing and publication” of another author’s “language, thoughts, ideas, or expressions” and the representation of them as one’s own original work.

Examples of Plagiarism

There are dime a dozen examples of plagiarism and some of them are as follows:

  • copying someone else’s work without citing them properly,
  • paying an external writer/essay mill to write the essay on your behalf,
  • stealing ideas and verbal conversations (overheard during discussions etc) and presenting them as your own,
  • copying data from websites, library books and other sources verbatim,
  • using someone else’s images, music, videos and even style of writing in your own work without their explicit permission is a punishable plagiarism example.

What Are the Different Types of Plagiarism?

Plagiarism can commonly be divided into 5 types. They are as follows:

  • Direct plagiarism: Copying someone’s work verbatim (word by word) without giving credits.
  • Self-plagiarism: Copying or producing an assignment influenced by your own previous work (also called unintentional plagiarism).
  • Mosaic or patchwork plagiarism: Quoting someone else’s work without quotation mark or changing the language (of original work) while keeping the structure same.
  • Accidental plagiarism: Unintentionally forgetting to cite the original work, misquotation etc.
  • Outsourcing: Paying essay mills, friends, hiring article writers, bloggers to write on your behalf.

We’ve tried to balance this list by including free and paid tools for plagiarism detection. Make sure to choose the one that fits your bills.

FAQs About Plagiarism Detection Tools

1. are free plagiarism checkers efficient enough.

No. No matter what the plagiarism software or plagiarism website tells you on the face, free plagiarism checker tools are not half as efficient as paid ones. If you see, most free versions of plagiarism checkers have a upsell to a paid plan. That’s why free plagiarism checkers are not efficient.

2. Are Premium Plagiarism Checkers Worth The Money?

Yes. Premium plagiarism checkers provide a plethora of tools and features like Deepsearch, checking for contextual plagiarism, multiple file uploads, single institutional account for multiple usernames, analytics, etc.

3. What to do when you find duplicate content or your content is plagiarized?

If you’re a teacher scanning students’ submissions and find duplicate content, you can take action against this academic dishonesty based on the level of copied content. In serious instances, you could terminate the student from school (or as your official manual says). If you’re a website owner and find someone copying your website, you can file a DMCA takedown notice. Alternatively, you can file a Google Copyright Removal which is free and hassle-free. It also gives you the liberty to file a lawsuit against copyright infringement.

4. Is plagiarism similar to copyright infringement?

No, plagiarism is not similar to copyright infringement. The latter is more bound by legal procedures and is taken as a criminal offense. However, plagiarism is considered dishonesty and might lead to a criminal offense in certain cases.

5. Did I plagiarize?

To know if you plagiarized or not, simply scan your document through any of the above online plagiarism checker tools and notice the result. A plagiarism report of 10% or low is generally not considered an offense in academic plagiarism. If it exceeds more than that, you have to double-check your document to see if you copied content or forgot to cite them properly.

6. Can I copy text from Wikipedia?

Yes, as long as you cite the source accurately giving credit where it’s due, you can use text from Wikipedia in your writing. Wikipedia’s content is licensed under Copyleft ( CC-BY-SA & GNU Free Documentation License or GFDL) which means you are free to reuse and modify as long as you attribute the source. But, if you’re a website owner, reusing Wikipedia content cannot help you to rank your website as Google loves fresh and new content.

Now, I can feel relieved because there are many alternative tools apart from Copyscape. For Grammarly, it seems I’ve heard about it and seemed to be relied upon to perform its job. Thanks for sharing this great list with us, Swadhin.

Keep up the good work and have a great week ahead!

Hey Swadhin,

excellent round up of plagarism checking tools,

The one tool that I have used over the past decade is Copyscape. I like the premium version though as it allows me to copy/paste the entire article and check for duplicates.

I still haven’t used Grammarly, that is on top of my things to do, and will surely check it out soon.

I have heard about most of the tools that you have mentioned, will take a look at the ones that are new.

thanks, Uttoran Sen,

Swadhin, thanks for sharing a great resources list here.

Well, actually to care about plagiarism checking for our content is great way to dial with duplicated content. I believe that everyone know exactly how Google hate those duplicated content.

I always use SmallSEOTools for check my blog post, but some blogger friend told me that it is not work well. I mean the report not accurate and unreliable.

Anyway, thanks for providing me more resources.

I would say that it is a great post for bloggers. I stumbled with the huge of plag check tools, I know only few tools and I mostly use Plagscan and plagiarism checker from SmallSEOTools.

You’ve neatly explained about copying content and yes, it is a big headache for bloggers. I have many bad experiences with content copying and If found any, I politely request the blog owner to remove that. Some bloggers accepted to delete that type of content but few of the bloggers didn’t worry with it. I don’t have any issues but they will hit by Google animals soon.

I have similar kind of post in MMF where I’ve shared my bad experience.

Since I’d started blogging a year back since i was new and wasn’t aware of do’s and don’t of blogging and faced such problem. I was only aware of copyscape and smallseotools that i came to know later on as i was searching learning. Since copyscape tell the overall site Plagiarism Check moreover with a number of limited searches being new and having highly copied content it was difficult. If I would have had this list that time it would have surely reduced my time.

Hello Swadhin,

Helpful list…………!!!

Plagiarism is worst thing in internet world because many peoples steal contents as well as other’s work without prior permission and used as own work. The original author or owner doesn’t aware about it so above free tools are really useful for them to protect their own work.

Thanks again for sharing really useful free plagiarism tool list to protect their own work…….Have a nice day…….!!!

Hi Gangadhar, Its true. Its not only disappointing for the owner but also cheating for the readers and viewers who think they are looking at a original piece. Thanks and glad you liked the post. Have a happy week

Hi Swadhin, Thank you so much for this post. You have right timing bro. I was looking for a perfect, free online plagiarism checkers. During the time, I just visited your blog and saw this latest post. This one seems it is exclusively written for me. Thank you so much bro. Among the list, I tried more than 5. Some tools demand to sign-up while others can’t check for plagiarism if the text we enter is a bit longer. So after the fruitless tries, I found Small SEO Tool’s plagiarism checker more useful and it shows how much unique our content is on the basis of percentage. I used it and I am completely satisfied with it. Keep going bro. Regards, Rahul

Hi Rahul, thanks for the kind words. Glad my post was on time to help you. I also think smaalseotools to be a better option and many bloggers use them too. I think plagiarism tools that do not ask for sign ups are great but I would not hesitate giving them my id. In fact I have a rough id for all those sign ups :)

These tools are handy Swadhin. I use copyscape premium version and that is working fine. Free ones are good too. The list is huge and one can find the plagiarism tool of their choice. Nice write up with a great list.

Hi Atish bro, thanks for saying that. Ohh wow you use copyscape premium version for protecting your online content? Thats so good to here. I rarely have seen people invest in such a thing and they should invest in such useful plagiarism detection tools.

That was an informative post indeed :)

I think you covered up everything one wanted to know about plagiarism very well in this post, and it is a great resource for bloggers, new and old. I liked the way you started the post, with the very basic of what is plagiarism, it’s kinds, and the best free tools, and then the paid ones too – you know I like that kind of format myself :)

Yes, you are right – with so many blogs coming up each day, it’s tough for bloggers to be original, and that can only happen if you visit less blogs and write on your own. Yet, for new bloggers that’s not easy, as they tend to read and then learn the right ways, and it’s a process that takes place slowly. We cannot really blame them for they don’t know, till they reach a certain stage in their blogging career. I guess giving due credit to the post author is the right way, even if you take a few pieces of text from the original post.

Honestly speaking, many people copy our posts too, but they are kind enough to link back or put up the original authors names, and all this your Google analytic also shows you, as you don’t always get the pingbacks.

Nevertheless, these are a great list of plagiarism checker tools, and I’ve used most of these, being a freelance writer also, and now of course when one’s blogging also. More than your own posts, it’s the guest posts one needs to scan through, especially if you don’t know the person. I hadn’t heard of the WordPress plugin for checking plagiarism, though it’s not been updated for a while now and not many downloads too. Yes, Copyscape is a good paid option, so is Whitesmoke as I’ve seen many writers use these, though we could always use the free options as and when needed. I know Grammarly has a great one too.

Thanks for sharing this with us. Have a nice week ahead :)

Hello Harleena maam, Thank you maam for the appreciation, I thought to have a post that in a way tries to answer most (if not all) questions writers have . I am learning all these formatting from you and other good blogs. So yes I am still learning to craft the perfect blog post.

Yes maam, we cannot just blame anyone and end the game. The novice bloggers are doing so becuase they aren’t aware about it. But then there are some that do it as a profession. The article spinners and the content mills produce these type of original content and harm both the owner’s credibility and the readers’ trust. I must admit, I was unaware Google analytics have this kind of feature. updates of plugins is not seriously a factor as I had recently read in a post. But yes whitesmoke and grammarly are great option. Copyscape is fantastic if we shell a few dollars. :) Have a great week maam :)

A really huge list of Plagiarism checker tools. All these are very useful. I’m using Small SEO tools from a long time and think most of the bloggers use the same.

No doubt Grammarly is best choice for those who are looking for Grammar checker, a proofreader and plagiarism checker, all in one tool. Although it’s paid tool but free version also offer some good service.

Thanks for sharing these 20 tools list here. I’ll also update my post :D ~ Ankit

Hello Ankit bro, welcome over here, am glad you liked the post. Yes small seo tools is what most use even I do it sometimes. Hahaha I did not know you have a post on plagiarism checker tools also :)

Top 10 Plagiarism Checkers for Accurate and Reliable Detection

Key takeaways:.

  • Many top plagiarism checkers, like Grammarly and Quetext, offer seamless integration with Google Drive for easy document uploads.
  • Advanced tools use sophisticated algorithms to minimise false positives, ensuring accurate detection of duplicated content.
  • Premium plagiarism checker software provide robust customer support, often accessible via contact forms, to address user queries and issues promptly.
  • Some duplicate content detecting tools employ contextual analysis to better understand and identify nuanced duplications in the content.
  • Effective plagiarism checkers generate detailed reports, including a list of sources and similarity percentages, to help users understand and address any potential issues.

In the digital age, where information is easily accessible and shareable, maintaining originality in written content is crucial.

Whether you’re a student, educator, researcher, content creator, or professional writer, ensuring that your work is free from plagiarism is essential to uphold academic integrity and professional credibility.

Plagiarism checkers are valuable tools that help detect and prevent unintentional plagiarism . In this article, we’ll explore the top 10 plagiarism checkers available today, highlighting their features, pros, and cons.

Why Plagiarism Checker is a Must-Have for Students?

Learners gain a great deal by having a plagiarism detector in their resources. This is the reason why:

  • Protection Against Inadvertent Plagiarism: Students may unintentionally copy text by failing to properly credit their sources, paraphrasing their ideas in an unprofessional manner, or failing to recognise when they have copied too closely. These inadvertent errors can be detected by a plagiarism checker before they become significant problems.
  • Ensures Academic Integrity: Academic integrity is paramount in education. Using a plagiarism checker demonstrates a commitment to honest and original work. It shows the instructor you’ve taken steps to avoid plagiarism and upholds the academic code.
  • Boosts Research and Writing Skills: The feedback provided by some plagiarism checkers can actually improve research and writing skills. By identifying areas where citations might be missing or paraphrasing needs work, students can learn proper citation styles and how to effectively express ideas in their own words.
  • Confidence Before Submission: Running a plagiarism check before submitting an assignment can give students peace of mind. Knowing their work is original allows them to submit with confidence, reducing anxiety about potential accusations of plagiarism .
  • Enhances Time Management: Time is saved by identifying plagiarism early on. Fixing citation errors ahead of time makes it lot easier than rushing to redo sections of an assignment after it’s due.
  • Levels the Playing Field: With so many resources available online, it can be tempting to take shortcuts. A plagiarism checker helps ensure everyone is playing by the same rules and completing assignments based on their own understanding of the material.

How Do Plagiarism Checkers Work?

how do plagiarism checkers work

Plagiarism checkers act like digital detectives, meticulously searching for instances where your writing might be unoriginal or derivative. Here’s a breakdown of their modus operandi:

Text Breakdown: The checker dissects your submitted work, breaking it down into smaller chunks like phrases or sentences.

Comparison Engine: These fragments are then fed into a vast database of existing scholarly sources, articles, online content, and potentially even student paper archives (depending on the checker).

Similarity Detection: The checker acts like a bloodhound, sniffing out matches between your text segments and the content within the database.

It employs sophisticated algorithms to identify not just exact word-for-word copying, but also instances of close paraphrasing or borrowing of ideas without proper attribution.

Highlighting & Reporting: Once potential matches are identified, the checker flags those sections in your work. It then generates a report that details the flagged areas, often providing information about the source material and the similarity percentage.

Filtering Options: Some checkers allow you to exclude specific sections from the scan, such as bibliographies or quoted passages. This helps ensure the report focuses on the originality of your analysis and writing.

By employing these techniques, plagiarism checkers act as a safety net, helping students and researchers identify areas where their work might inadvertently infringe on the originality of others.

It’s important to remember that plagiarism checkers are tools, not arbiters of truth. A high similarity score doesn’t necessarily mean plagiarism, but it indicates a need for closer examination and proper citation if applicable.

Free Vs. Premium Plagiarism Checker

Free duplication checkers are suitable for basic needs and occasional use, offering limited features and accuracy.

On the other hand, premium checkers provide comprehensive coverage, advanced features, and superior accuracy, making them ideal for academic, professional, and frequent use. 

Here’s a comparison of free and premium duplication detection tools to help you decide which one suits your needs:

  • Budget: Checkers range from free to premium. Assess your needs and choose a plan that delivers the most value for your money. Consider student discounts offered by some paid checkers.
  • Features: Checkers offer a spectrum of functionalities. Some focus solely on unoriginal content detection, while others integrate grammar and style suggestions, paraphrasing analysis, or multilingual support.
  • Security and Privacy: Your documents should be secure, and your data should be private. Ensure that the tool you choose has strong security measures in place and does not store or misuse your submitted content. Reading the privacy policy can provide insights into how your data is handled.

Here are some additional pointers to steer you towards the ideal replica detection tool:

  • Accuracy is Paramount: The most crucial aspect is the checker’s ability to effectively identify potential instances of uncredited borrowing , even when the source material is paraphrased or cleverly disguised.
  • Database Depth: A wider database net means a higher chance of catching potential content duplication , even from obscure sources.
  • Integration with Other Tools: Take into account if the duplicator is compatible with the platforms and applications you now use. Integrating learning management systems and word processors like Google Docs, Microsoft Word, and others can expedite and improve the checking process.
  • User Interface: A user-friendly interface makes navigation a breeze. Look for checkers with straightforward document upload, report generation, and clear result interpretation.
  • Free Trials: Many paid checkers offer free trials. Utilise these to test-drive features and assess their suitability for your needs.
  • Reviews and Comparisons: Research online reviews and comparisons of different checkers. This can provide valuable insights from other users and help you narrow down your options.

Through careful consideration of these variables and study, you may choose the literary theft detection instrument that best suits your needs and protects the originality of your work.

To guarantee the originality and integrity of your work, safeguard it with the best plagiarism checkers .

Remember, an accurate plagiarism checker is a valuable asset, but it shouldn’t replace your own research and writing skills.

Always strive to comprehend the concepts you’re exploring and express them in your own unique voice, with proper attribution where necessary.

How Can I Avoid Plagiarism in My Content?

Here are some key strategies to steer clear of unintentional literary theft and cultivate original content :

Deepen Your Understanding

Thorough comprehension of the subject matter is paramount. When you grasp the concepts, you can express them in your own words and avoid simply regurgitating information from sources.

Meticulous Note-Taking

Develop a note-taking system that clearly distinguishes your ideas from those gleaned from sources. Include citations within your notes to ensure proper attribution later.

Paraphrase Effectively

When using information from other sources, paraphrase it instead of copying it directly. This means rephrasing the ideas in your own words while retaining the original meaning. Effective paraphrasing shows that you have processed and understood the information.

Use Quotations

When you need to use exact wording from a source, use quotation marks and give proper credit to the original author. This practice is essential for acknowledging the original work and avoiding duplication.

Cite Your Sources

Always provide proper citations for the ideas, data, and direct quotes you use in your content. Different disciplines have different citation styles (such as APA, MLA, Chicago), so make sure you follow the appropriate format. Citation generator can you help you in this.

Utilise Multiple Sources

Drawing information from a variety of sources helps create a more comprehensive view of the topic and reduces the risk of duplicating any single source. This approach also enhances the depth and breadth of your content.

Create Original Ideas

While researching, develop your own insights and arguments. Originality often comes from synthesising information from multiple sources and adding your unique perspective.

Remember Voltaire’s saying:

“Originality is nothing but judicious imitation. The most original writers borrowed one from another.”

Use this principle to inspire creativity while respecting the work of others.

Use Plagiarism Checkers

Duplication detection tools can help ensure your content is original.

These online tools scan your work against extensive databases to identify any potential matches with existing content. Using them as a final check can help you catch any unintentional copying.

What’s Next?

Choosing the right duplication detection tool is crucial for maintaining the originality and integrity of your work.

The top 10 plagiarism checker tools we’ve explored offer a range of features to suit different needs, from academic to professional use.

Tools like Bytescare, Turnitin and Grammarly provide comprehensive content databases and detailed reports, while options like Copyscape and Quetext offer user-friendly interfaces and effective scanning capabilities.

What is the most accurate plagiarism checker?

Unfortunately, there’s no single “most accurate” tool. Each checker has its strengths and weaknesses. The rigorous testing process evaluates factors like: Detection Rate: How effectively the tool identifies unoriginal content , including paraphrasing and mosaic plagiarism. False Positives: How often the tool incorrectly flags original content. Database Size: A larger database increases the chance of catching matches, even from obscure sources.

Can plagiarism checkers detect paraphrased content?

Plagiarism checkers have varying degrees of success when it comes to detecting paraphrased content.

Some advanced tools use sophisticated algorithms that can sometimes identify paraphrased text by comparing it to their extensive databases. However, the effectiveness can vary, and these tools may miss paraphrased content if the wording has been significantly altered.

To enhance detection, some checkers analyse writing patterns and context, which helps identify more subtle instances of rewording.

Are free plagiarism checkers reliable?

Free plagiarism checkers can be reliable for basic checks, but they often come with limitations compared to premium versions. However, free tools typically have restrictions on the number of checks and the depth of their database coverage.

How we test the best plagiarism checkers?

Testing the best plagiarism checkers involves a thorough evaluation of various features and performance metrics.

Firstly, we assess the accuracy of each tool by running tests with known plagiarised content to see how effectively the tool identifies the copied text. We also evaluate the comprehensiveness of the reports generated, looking for detailed analysis and clear presentation of results.

Additionally, we consider user experience, including ease of use, speed of analysis, and the ability to handle different file formats. Finally, we test the tool’s integration capabilities with other platforms and its ability to detect paraphrased content.

What are the key features to look for in a plagiarism checker?

When selecting a plagiarism checker, it is important to focus on a few key features to ensure the tool meets your needs.

First, consider the tool’s accuracy. The best plagiarism checkers have extensive databases and sophisticated algorithms that can detect even the slightest instances of copied content.

Second, look for comprehensive reporting capabilities. The tool should provide detailed reports highlighting matched sources and the percentage of plagiarised content.

Third, check if the plagiarism checker supports multiple file formats and integrates seamlessly with your preferred word processors or content management systems.

How do plagiarism checkers help students and educators?

Plagiarism checkers are invaluable tools for both students and educators. For students, these tools help ensure that their work is original and properly cited, reducing the risk of unintentional plagiarism.

Educators benefit by being able to quickly verify the originality of student submissions, maintaining academic integrity. Additionally, plagiarism checkers often provide suggestions for proper citations and references, aiding students in learning correct academic practices.

Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many cheap essay writing services use a plagiarism checker for research paper. However, students sometimes forget that they should too. But with so many options that pop up when you ask Google to “check my paper for plagiarism”, how do you choose the right one for detection? We’ve got the solution in the form of PapersOwl’s free plagiarism checker tool! Our simple tool makes it convenient to check any writing task without having to spend a dime. It works quickly and highly accurately, ensuring that you get the top grade you deserve. So, if you want to check plagiarism online before turning your task in, head over to our website and get started!

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

PapersOwl’s plagiarism detection tool gives you all the information you need to fix plagiarized content. Whether you’ve fallen victim to accidental plagiarism or have tried to make your life easier by copying some text from different sources, you’ll get an accurate percentage with our plagiarism checker online. If you’re wondering how to check paper for plagiarism, it’s nothing complicated at all! Simply visit our site, paste your whole essay into the relevant text box or upload the text file, click on Check For Plagiarism, and you’ll get accurate plagiarism results in a matter of seconds. You’ll see the problematic parts with plagiarism detected highlighted, with links to where similar content exists. Our service with plagiarism detector will also give you the option to check my essay for plagiarism and then to hire a professional paper writer to fix your task quickly if you're busy with other things!

The Fastest Plagiarism Checker Online

Gaining insight into duplicate content only works if you get your results quickly. There are so many free plagiarism software online that promise to do the job for you. However, a lot of them are clunky, slow, and inaccurate. How can you produce original work without similarity detection you can trust?

PapersOwl stands out in this regard because it will detect plagiarism in seconds. This is a plagiarism scanner that’s able to perform a Swift Check to give you a uniqueness check right there and then. It also conducts a Deep Search, going through millions of sources on the internet to check for plagiarism. A document of about 1500 words takes only about 10 seconds to get processed! You get a clear plagiarism score of how much text is plagiarized and how much is original. All the sources that your essay matches are listed based on how much similarity there is in your academic writing. And on top of that, you get a handy Make It Unique button that’ll take you to an order page where you can ask our expert writers to rewrite your work and make it 100% unique.

All of this is done almost instantly, allowing students to continue do assignments without missing a beat. Not every plagiarism detection software works this quickly, making ours the best one you’ll ever use.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly. Turning such a paper in can cause multiple problems, as your professor might think you haven’t done the work at all.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose. A simple, free plagiarism check could help you check plagiarism, fix any mistakes you see, and submit high-quality text that no one will question.

Our plagiarism detector has a lot going for it. It makes plagiarism detection easier than ever before. Unlike copying and pasting each passage individually into Google, simply upload the whole file into our plagiarism checker free for students, and you don’t have to do anything else. All the matches are highlighted so you know what to change.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required. So, using our copyright checker online free to check your writing is essential. This way, you’ll submit the task only when you’re sure it meets the level of uniqueness required by your school. As a result, your grades will drastically improve when you check for plagiarism.

What is QuillBot AI?

quillbot AI tool

QuillBot AI is a leading AI writing companion and paraphrasing software designed to help anyone elevate the quality of their writing. At its core, it functions as one of the best AI rewriter tools to edit, rephrase, and enhance content like a professional.

It presents various features, including grammar checking, plagiarism detection, and content summarization. As such, QuillBot AI delivers substantial benefits for academics, essayists, and writers. Creating high-quality professional content can be time-consuming, and Quillbot streamlines the process using AI to improve your writing quickly, offering real-time suggestions and one-click solutions. Plus, it is an all-in-one solution that replaces the need to invest in multiple tools, making it cost-effective.

The versatility of the software caters to a diverse audience. While students can utilize its various writing tools, professional writers can efficiently collaborate and summarize lengthy text. If you want to improve your writing process, whether writing an email, an essay, or a long-form blog article, you will find Quillbot AI to be a valuable addition to your writing toolkit. It can revolutionize your writing process to produce surprising results.

How Quillbot AI Works

You can access QuillBot by visiting their online platform on their website . You don’t need to create an account; you can use a free version of QuillBot with limitations. Once you are there, you will see the available tools in the left sidebar. Click any of the tools to launch the user interface for each.

QuillBot User Interface

Each tool will have a consistent layout with different features that you can use to start refining your content. For example, when using the Grammar Checker, you can copy and paste your content into the user interface. QuillBot will readily analyze your text, pinpointing broken sentences and grammatical errors you can fix with a single click.

And the other other tools share the same easy-to-use interface and functionality. For instance, the Summarizer makes condensing long-form content or essays easy. Paste your text to generate a summary of key points. Additionally, it features a plagiarism checker, which helps identify and fix plagiarized content to ensure the originality of your content.

QuillBot’s AI functions by learning from datasets. Comprehending grammar, spelling, punctuation, tone, sentence structure, and readability, these datasets serve as knowledge accumulations. So, when users regularly disregard a specific suggestion, the AI adjusts to present more contextually relevant alternatives.

Breaking Down QuillBot AI Features

QuillBot AI offers several features for easy and effective content organization. We’ll delve into these features now.

1. The Paraphraser

QuillBot AI includes a paraphrasing tool. It empowers writers to rephrase text while preserving its central message. It’s an ideal tool for students and aspiring authors, requiring no account signup. Options for ‘Fewer Changes’ or ‘More Changes’ are available, with premium users getting maximum adjustments.

Paraphrase Modes

QuillBot AI assists users in paraphrasing and refining text. It employs seven unique modes, each tailored to specific objectives, to enhance the quality and readability of written content. Whether striving for clarity, professionalism, creativity, or conciseness, QuillBot AI offers a mode to suit your needs.

Here is an example sentence I added to the paraphraser text input area:

“It was a tough match. After three hours of immense struggle, I was able to get the job done.”

1. Standard Mode

Standard Mode serves as the default setting. It balances modifying the text for clarity and fluency while preserving the original meaning. The result is a refined text that maintains its natural flow and readability.

After clicking the Rephrase button, QuillBot swiftly provided a paraphrased output in Standard Mode. It merits noting that the level of paraphrasing hinges on the level of synonyms you set in the Synonyms bar at the right of the Modes bar above the content. The higher the level, the more liberty you give QuillBot to change the words of the original content.

The ensuing result was generated with a low Synonyms bar:

“It was a challenging game. I had to struggle for three hours before I was able to finish the task.”

quillbot ai standard mode

The following result was generated with a maximum level of Synonyms:

“It was a challenging game. I had to battle for three hours before I was able to finish the task.”

quillbot ai standard mode

With just one sentence, you can see that only one word changed, but with larger blocks of content, you will see that QuillBot will make more word changes with a higher level of synonyms.

2. Fluency Mode

In Fluency Mode, QuillBot AI ensures that the text is grammatically sound and genuinely readable. It makes minimal changes, primarily correcting grammar and providing the text sounds natural. Synonym substitutions are kept to a minimum, preserving the original meaning.

We paraphrased the same content in Fluency mode . It generated the following output:

“It was a difficult match. I completed the task after three hours of intense effort.”

quillbot ai fluency mode

3. Formal Mode

Formal Mode is the ideal choice for those working in academic or professional contexts. It transforms the text to sound more polished and professional, making it suitable for business reports, academic papers, and formal documents.

We paraphrased the same content in Formal Mode . It generated the following output:

“ It was a difficult match. After three hours of arduous effort, I was able to complete the task. ”

quillbot ai formal mode

4. Academic Mode

Then, we paraphrased the same content in Academic Mode . Unlike the other modes, it doesn’t have any Synonyms bar. Instead, it seemed to give the content more details and wording suitable for academia. It generated the following output:

“ The contest was challenging. Following a prolonged period of three hours, characterized by significant exertion and effort, I successfully completed the task at hand. ”

quillbot ai academic mode

5. Simple Mode

Simple Mode simplifies the text, making it easier to understand and more accessible to a broader audience. It is an excellent choice when clarity and straightforward communication are essential.

We paraphrased the same content in Simple Mode . It generated the following output:

“ It was a hard game. I was able to finish the job after three hours of hard work. ”

quillbot ai simple mode

6. Creative Mode

Creative Mode is the way to go if you’re looking to unleash your creativity and generate entirely unique content. This Mode substantially changes the text, potentially altering the original meaning. It’s a valuable tool for content creators seeking a fresh spin on their writing.

We paraphrased the same content in Creative Mode . It generated the following output:

“ That was one intense contest. It took me three hours of relentless effort, but I finally completed the task at hand. ”

quillbot ai creative mode

7. Expand Mode

Expand Mode is perfect for those aiming to increase the length of their text. It adds words and details while retaining the original meaning, making it valuable for projects requiring a higher word count.

We paraphrased the same content in Expand Mode . It generated the following output:

“ It was a difficult match to watch. I had to put in a lot of effort for three hours before I was finally successful in completing the task. ”

quillbot ai expand mode

Then, we produced an output with a high level of Synonyms as follows:

“The contest was a challenging one. I was able to finish the work, despite the fact that it took me three hours of intense effort.”

quillbot ai expand mode

8. Shorten Mode

Shorten Mode comes to the rescue when you need to reduce the overall word count while maintaining the essence of your text. It trims unnecessary words and phrases, delivering a concise version of your content.

Lastly, we paraphrased the same content in Shorten Mode.  It generated the following output:

“ The match was hard. I finished after three hours of intense struggle. ”

quillbot ai shorten mode

Paraphraser Statistics

The ‘Statistics’ feature offers insights into text complexity and readability. It aids writers in adjusting their style to the desired tone and audience. Premium subscribers unlock tonality analysis, which assesses reader perceptions to enhance persuasive writing.

I have used the same content as the previous one in the “Fluency” mode. It has generated the following statistics.

quillbot ai statistics

The Statistics of the generated content are based on the following aspects:

  • Average words in a sentence
  • Average Syllables in a word
  • Readability
  • Sentence Count
  • Character Count
  • Percent Change
  • Longest Unchanged Words

Paraphraser Settings

quillbot ai settings

The “Settings” feature in the Paraphraser tool provides options to control how you want your content to be paraphrased and how you want the results to be displayed on the interface. In terms of paraphrasing the content, you choose the following:

  • Paraphrase quotations
  • Use contractions
  • Prefer active voice

Under the Interface options, you can select the following:

  • Use yellow highlight
  • Show tooltips
  • Show legend
  • Show changed words
  • Show structural changes
  • Show the longest unchanged words

Overall, these settings do seem to give users more control and help them identify changes to their content much easier.

Paraphraser Compare Modes

Compare Modes is a valuable feature exclusively available to premium users, offering a comprehensive view of how a sentence is transformed across different modes within the platform. This feature enables users to evaluate and choose the most suitable rendition for their content by comparing various paraphrased versions. To access Compare Modes, locate and click on the dedicated icon in the settings bar on the right side of the page.

quillbot ai compare modes

Once activated, Compare Modes opens a sidebar on the right-hand side of the screen, displaying the original sentence before paraphrasing and the results generated by all available modes simultaneously. The system defaults to the effect produced by the Mode in which the sentence was paraphrased. You can easily click the “Select” button next to the desired text to select your preferred sentence, seamlessly replacing the paraphrased sentence in your results. Additionally, you can further modify individual sentence results by clicking on circular arrow icons or making copies of them with a simple click on the copy icon. This powerful feature empowers users to fine-tune their content according to their specific needs and preferences, streamlining the content creation process.

Paraphraser History

By accessing the history feature, you can go through all the previous content you have modified. In my case, I checked my history, and it showed the last text paraphrased. It also shares the date and time when the content was modified.

quillbot ai history

The “Tone” feature in QuillBot AI paraphraser allows users to control and tailor the emotional and stylistic tone of their paraphrased content. With this feature, users can choose from various preset tones, such as casual , unfriendly , wordy , complex , and unclear . It ensures that the paraphrased text aligns perfectly with the desired style and intent. Whether you need your content to sound professional and academic or friendly and conversational, the Tone feature empowers you to achieve the right mood for your writing.

quillbot ai paraphraser tone

Paraphrasing for Different Languages

Quillbot AI supports 23 different languages for paraphrasing purposes. Not only does this make the tool more accessible, but it also comes in handy for making tweaks to the content generator by Quillbot’s translator tool.

quillbot ai languages

2. The Grammar Checker

Quillbot AI offers a user-friendly and free Grammar-checking feature that doesn’t require signing up. When you paste your text into Quillbot’s editor, it identifies and highlights grammatical errors, including punctuation and spelling. With a convenient Fix All Errors option, you can swiftly correct multiple issues simultaneously. This Grammar Checker enhances writing precision and consistency. It quickly pinpoints potential errors in red, simplifying the editing process. This real-time underlining and instant correction feature saves writers time and improves productivity.

For instance, here is an example sentence I added to the grammar checker text input area:

“ Manchester United signed Sofyan Amrabat on a season-long loan move from Fiorentina. The Morocco midfielder has been desperate to join Erik ten Hag’s team since getting linked to the Red Devils in June. However, Manchester United’s plans differed on Deadline Day as they wanted to sign Fulham’s Joao Palhinha instead. ”

After copy-pasting the text into the Grammar Check, it will detect all the potential errors within the content. By putting your cursor on the underlined words, it will show you the errors individually.

quillbot ai grammatical errors

Once you remove all the errors, it will provide you with the correct grammatical content. It will generate the following content.

“ Manchester United signed Sofyan Amrabat on a season-long loan deal from Fiorentina. The Morocco midfielder has been desperate to join Erik ten Hag’s team since getting linked to the Red Devils in June. However, Manchester United’s plans were different on Deadline Day, as they wanted to sign Fulham’s Joao Palhinha instead. ”

quillbot ai grammar errors removed

Furthermore, it seamlessly integrates with Quillbot’s Paraphrase tool, offering a comprehensive writing experience without needing an account. Its grammar-checking feature is valuable for writers seeking error-free, professional content.

3. Summarizer

Quillbot AI provides a Summarizer tool that condenses lengthy texts or articles into concise summaries, making it invaluable for students, researchers, and professionals.

Users can choose between Short and Long summarization options to control the level of detail. The Short summarization offers a brief overview, ideal for quickly grasping the central ideas or skimming through multiple articles. In contrast, the Long outline provides a more comprehensive summary, suitable for in-depth analysis or a deeper understanding of the text.

Quillbot AI’s Summarizer utilizes natural language processing to extract critical information while preserving the original context. It offers two summarization types: Key Sentences and Paragraph modes.

For instance, I added a block of content to the summarizer text input area. Using the Key Sentences feature, the tool has created five articulate points that summarize the content.

Changing the Summary Length can increase or decrease the depth of those points.

Selecting the Paragraph mode will provide a summary of the content in paragraph form.

Like the Key Sentences mode, the length of the summary can be changed by adjusting the Summary Length .
