Plagiarism Checker

Even if the original phrasing has been changed, the finest plagiarism checker should be able to detect plagiarism with the greatest accuracy. A clear, detailed plagiarism report should also be provided by the tool.

You will get all link below.

We did in-depth research evaluating the efficacy of 10 plagiarism checkers to determine which one is the best. We posted plagiarized texts that were either copied and pasted verbatim or little altered. In total, 180 sources were utilised to create our test documents.

According to our extensive study, the Scribbr Plagiarism Checker for Students is the finest plagiarism checker available in 2022. It can detect plagiarism in exact copies as well as substantially altered plagiarized writings and generate a clear report.

Our method for comparing checkers is as follows:

We examined several features of the programs in order to determine the best plagiarism checker for kids, concentrating on both depth and breadth.

Our research was based on the following factors:

Access to the world’s most comprehensive and diverse database

Ability to detect the most plagiarism across the widest range of sources

When plagiarized texts have been paraphrased, the ability to detect plagiarism has increased.

Highest level of match quality

User-friendliness and trustworthiness levels

To compare the plagiarism results fairly, we used the same test documents, evaluation criteria, and data analysis for each program. As a result, we had to do very little interpretation of the results.

We wrote an essay that covers the study process in further detail in order to make our research as transparent as feasible. We also provide links to our test documents as well as an in-depth research report.

For all types of sources relevant to students, such as journal articles and dissertations, Scribbr worked admirably.

Most notably, Scribbr’s plagiarism checker was the best at identifying plagiarism in substantially altered source texts to imitate unintentional paraphrase plagiarism. The plagiarized elements have been underlined in the screenshot, however the altered words have not.

Scribbr was able to find complete matches as well. This means that instead of many wrong sources, the entire plagiarized piece is accurately matched to just one source.


The findings are summarized in an easy-to-understand format that can be downloaded. Users may easily examine each plagiarism concern separately because various colors are utilized for different sources.

Issues can be resolved with Scribbr’s free Citation Generator, which provides accurate citations for any sources that have been overlooked or wrongly cited.

Users can also use the Plagiarism Checker in conjunction with the Scribbr-exclusive Own Sources Checker. In addition to the public database, this application allows users to upload their own unpublished papers.

Scribbr charges per plagiarism check ($19.95–$39.95, depending on the word count) rather than forcing consumers to subscribe to their services.

Users, on the other hand, are unable to operate directly in the tool, and you cannot re-check your paper for free.


Scribbr does not save or sell uploaded documents, nor does it share them with academic institutions. Following 30 days, data is automatically removed, or students can choose to delete their document individually after the check.

Scribbr offers live and prompt customer service in several languages to help students. A plagiarism checker guide and other free plagiarism materials are readily available.

Although Quetext detects the majority of plagiarism, it is impossible to match the complete source text to a single source. Instead, individual sentences are assigned to many sources, resulting in a large number of false positives.

Quetext tests against web pages and academic sources, according to the website, although the program does not do well with academic materials.


In its downloaded report, Quetext distinguishes between partial and full matches based on the severity of plagiarism. Aside from that, the same colors are used throughout all sources.

Although working directly with the tool is not possible, Quetext does provide a citation aid that assists in the generation of missing citations.

A free trial allows users to check up to 2,500 words, after which they must subscribe for $9.95 per month.

Grammarly detected some cases of plagiarism, but it struggled with substantially modified texts.

The tool was able to locate the correct source in the majority of cases, although the matches were just partial, not highlighting the complete plagiarized piece. Grammarly exhibited more and more false positives as the degree of editing grew.


Although the design is simple, the tool uses the same color for all sources, which makes it difficult to understand.

Grammarly removes the original formatting when changing the text, but restores it after the document is downloaded.

The subscription includes a language and style tool as well as a citation aid that assists in the generation of missing citations, however it does not support APA style. In addition, both the monthly ($30 per month) and yearly ($12 per month) plans have a 100,000 character limit.

4. Unicheck review

Without authorization to share, does not sell or share documents.

Live assistance is available.


Finding the plagiarized source is tough due to the unclear report.

Different sources have the same highlight hues.

For a single plagiarized sentence, it returns numerous matches.

Matches of high quality

Unicheck frequently locates the intended original source, as well as other sources containing minor portions of the plagiarized material. As a result, instead of delivering a complete match with just one source, it attributes individual sentences to numerous sources. As a result, the report is unclear.

Although with various degrees of accuracy, the tool was able to detect some of the plagiarism in the altered text.


The downloadable report is a little difficult to read. Because the tool presents so many found sources in the sidebar, it is difficult to know what to do with each similarity.

The user is unable to identify between sources because all plagiarized elements are highlighted with the same color. The user must search the sidebar for the plagiarized source, which can be time-consuming and difficult.

Users can check up to 200 words for free, but after that, price is depending on page count ($5 for 20 pages, $10 for 50 pages, and $15 for 100 pages).

Matches of high quality

Most plagiarized sources were not found by PlagScan, especially if the source material had been modified. When it was able to identify a source, however, it was frequently correct.

PlagScan was also able to offer complete matches, resulting in an unambiguous plagiarism report. The tool worked better with common internet sources (such web pages) than with scholarly materials. Students and academic professionals may find it less useful as a result.

As the degree of editing increased, the performance deteriorated, resulting in several false positives.


The PlagScan utility used the same colors for diverse sources, despite the user-friendly interface. The plagiarized source text is not displayed on the sidebar; instead, it is opened in a new tab. This makes working directly in the tool impossible.

Users can check 2,000 words for free before paying for more ($4.99 for 5,000 words, $9.99 for 15,000 words, $19.99 for 35,000 words, and $39.99 for 80,000 words). You can move those words to another document if your document has less words than the one you purchased.

Unrestricted (max 1,000 words per search)
For different types of plagiarism, different highlight colors are used.


The majority of the plagiarism was not found.
Different sources have the same highlight colors, and the original formatting has been deleted.
Due of advertisements, the design is a bit jumbled (even on premium plan)

Matches of high quality

Even for the unedited text sections, Pre Post SEO was unable to locate the majority of the plagiarized sources. Furthermore, practically every match was just partial, attributing specific sentences to one or more sources rather than the full section.


For verbatim and paraphrase plagiarism, a separate hue was utilized, however the tool’s assessment was frequently incorrect. Aside from that, diverse sources were assigned the same color, and the original layout was eliminated, making the report difficult to read.

Despite having a premium plan, the website nevertheless displayed a lot of irrelevant and annoying advertisements.

To reconcile similarities, the user can utilize a rewrite tool, although the tool’s quality is poor, and it doesn’t help with citation difficulties.

Pre Post SEO is a free tool, but unregistered users can only search for 1,000 words at a time. A premium plan ($10–$45 per month) is available to users.

Pre Post SEO does not store or sell any of your documents. It does not provide live support, but it does have a form for requesting assistance.

7. Plagiarism Detector


Your document will not be stored or sold.


Finding the plagiarized source in the report is difficult.

Different sources have the same highlight hues.

There were technical issues with generating the report, and there was no live support.

Matches of high quality

Due to technical issues, this tool could not be evaluated properly. The plagiarism report only found matches for the first sources, and none for the sources at the conclusion.

Despite the fact that the paper did not surpass Plagiarism Detector’s word restriction of 25,000 words, it appears that Plagiarism Detector was unable to analyse it.


Because the same colors were used for multiple sources, the report was illegible and difficult to understand. When you hover over a plagiarized section, the source is not displayed. Instead, you’ll have to sift through a big list to find the source.

Plagiarism Detector includes a rewrite tool to help with similarity resolution, although the tool’s quality is unclear, and it does not address citation concerns.

The first 1,000 words are free, after which users must pay $10 for 100 searches (or 30,000 words).


Plagiarism Detector does not keep or sell any of the documents it receives. Although there is no live support, the website does have a form for requesting assistance.

8. Viper Review


You’ll be able to compare your most recent document to earlier ones you’ve submitted.
Different colors correspond to different sorts of sources.


If you utilize the free version, your documents will be published on other websites.
For scholarly sources, it performs poorly.
Due to partial matches, the report is difficult to read.

Matches of high quality

When the source text was explicitly duplicated, Viper discovered some plagiarism, but it struggled to locate it among altered texts.

For the most part, the program performed admirably, although it struggled with scholarly sources such as journal articles and dissertations. As a result, the tool’s utility for pupils is debatable.


Viper was frequently unable to identify an entire text to a single source. Instead, it merely credited a source for particular sentences.

Despite the helpful use of distinct colors for different sources, the downloadable report was rather difficult to understand.


Viper keeps track of prior entries and displays projects that are similar to them.

If you utilize the commercial version ($3.95–$26.30 per check, depending on word count), the program does not sell your content.

If you use the free version, however, the document is saved in an internal database. The text is uploaded on an external website after three months as an example for other pupils.

If the substance of your communication is confidential, this can present issues.

9. Compilatio Review


You can apply your credits to a variety of papers.
The report’s original formatting was preserved.


The plagiarized parts of the text are not highlighted.
Only a pdf is sent to you.
Plagiarism is difficult to investigate and resolve.

Matches of high quality

Compilatio was able to locate a couple of the plagiarized sources, but had difficulty determining if the source text had been changed. When it was able to identify a source, however, it was frequently correct.

Because the plagiarized elements were not underlined, it was impossible to tell whether Compilatio could genuinely match the source to a plagiarized source text.

Rather, the report just displays the broad area that corresponds to the source. This may limit its utility for consumers, as it is difficult to review and resolve potential plagiarism issues.

Matches of high quality

The report does not highlight the observed similarities in the text, making it difficult to read the report and obtain a solid understanding of the potential risks. Also, because you can’t work in the tool, you can’t exclude similarity from the report.

Users can purchase packages of 20 credits (5,000 words for $3.99), 100 credits (25,000 words for $14.99), or 200 credits (5,000 words for $29.99). (50,000 words for 24,99).

These credits are good for 12 months after purchase and can be used on numerous documents.

Compilatio does not distribute or sell the documents it receives, and the documents are not utilized as comparison material for other users.

There is no live support provided, however a helpdesk with FAQs and a request form is available.

10. Pro Writing Aid review


Multiple language and style tools are available.
The utility preserves the original formatting.
Texts are not saved or sold.


The report’s generation was plagued by technical challenges.
Different sources have the same highlight hues.
There is no live assistance available.

Matches of high quality

This tool could not be adequately evaluated. The plagiarism report only found matches for the first sources, and none for the sources at the conclusion. Pro Writing Aid appears to be unable to process a paper of this size.


The utility uses the same hue for all sources, making it difficult to tell them apart.

The report was straightforward, however matches were only shown when the user hovered over the highlighted phrase. In addition, the original formatting was preserved.

Language and style tools are included in the Pro Writing Aid plan ($24 per month), or customers can purchase standalone plagiarism checks ($10 for 10 checks, $40 for 100 checks).


There is no live support on the website, however there is a FAQ page and a help request form. Pro Writing Aid does not keep or sell any of the texts that are submitted.

Plagiarism is discovered in a variety of ways.

If the tone, formatting, or style of your content differs in different portions of your paper, or if they’re familiar with the plagiarized source, your professor or readers will be able to discover plagiarism.

Many colleges also employ plagiarism detection software such as Turnitin, which analyzes your content to a big database of other sources and flags any similarities.

Plagiarism by accident is more often than you might assume. To guarantee you haven’t overlooked any citations, use a plagiarism checker before submitting your paper.

Are plagiarism detectors reliable?

The accuracy of the plagiarism checker you employ is determined on the software you utilize. Scribbr is the most accurate plagiarism checker, according to our research. Many free plagiarism checkers can fail to detect all plagiarism or label content as plagiarism when it isn’t.

Plagiarism checkers operate by scanning your writing against existing texts using complex database technologies. Their precision is controlled by two factors: the algorithm (which detects plagiarism) and the database size (with which your document is compared).
