The best plagiarism checkers in full:

1. Ranksensei Plagiarism Checker


Free usage for scans up to 1,000 words per session.

Multiple options are available for uploading documents.

Documents are not stored in the database.


Limited detection of plagiarism.

The website is a little slow, and contains ads.

Focuses on scanning individual sentences rather than full texts.

Is it Free? 

Ranksensei offers free usage; however, the scan is limited to 1,000 words. You must complete CAPTCHAs to upload multiple documents if you require scanning beyond that limit.

Quality of Matches: 

Ranksensei displayed a low ability to detect plagiarism in our test documents, with an average accuracy of only 44%. Since it scans sentences separately, it produces partial matches.

The plagiarized text is highlighted, albeit in a single color. Clicking on the highlighted text reveals the corresponding source it was matched with.


The website appears cluttered with numerous ads that can be easily mistaken for the required buttons.

The generated report itself is relatively clear. While the tool highlights plagiarized text in a single color, it establishes links between matched text and their identified sources.


Ranksensei claims not to store checked content after analysis. Registration is not required to utilize the tool. Users also have the option to request personal data erasure by contacting the provided support email.

2. Grammarly 


Offers a language and citation assistant.

Does not sell or share files with third parties.


Not a free service.

Detects a relatively low percentage of plagiarism.

Uses the same colors for different sources, making results difficult to interpret.

Is it Free? 

Contrary to its advertised claims, Grammarly’s plagiarism checker is not free. The tool provides a screen that indicates the presence of plagiarism in your text without specifying the details, such as its location, extent, or the sources involved.

Upon receiving this notification, you will be prompted to download the Grammarly app and subscribe to their premium service, which costs $30 per month. Even after subscribing, a character limit remains 100,000 (approximately 20,000 words).

Quality of Matches: 

Grammarly can identify more complete matches compared to most free tools. However, its performance is notably weaker when dealing with academic sources, resulting in an overall low accuracy score of 40%.


As a premium service, Grammarly offers a visually appealing interface that is clearer than many free plagiarism checkers. The original format of a document is preserved. However, the tool uses the same color to represent all sources, making it challenging to differentiate between them and understand the results accurately.

Subscribing to Grammarly’s premium service also provides access to a language and style tool and a citation assistant.


Grammarly ensures the privacy of your documents and does not store, sell, or share them with third parties.

The website includes a support page containing helpful tips, tutorials, and FAQs. Additionally, users can submit questions through a form, although live support is unavailable.

3. Check-plagiarism.com 


Allows an upload limit of 1,000 words.

Offers a citation generator.


Challenging to match text with sources in the downloadable report.

Uses the same color for different sources.

Scans sentence by sentence, resulting in a few full matches.

Is it Free? 

The free availability of Check-plagiarism.com is uncertain. The website describes a free upload limit somewhat confusingly, mentioning a specific number of “queries” (sentences) per month. However, these limits were unclear and did not apply when we tested our documents.

Quality of Matches: 

Check-plagiarism.com performed worse than free tools, with an overall score of 39%.

While the tool managed to identify some full matches, it primarily detected partial matches. Using the same color for different sources compromised the report’s readability. Additionally, the tool often inaccurately distinguished between verbatim plagiarism and paraphrasing plagiarism, using different colors for each.


The platform allows you to check up to 1,000 words simultaneously for free.

In the downloadable report, the text’s format is preserved. However, the extensive list of sources makes cross-referencing with the corresponding text challenging.

The on-site version of the report offers slight improvements, featuring a box next to the plagiarized text that displays the identified source. A “rewrite” function and a manual citation tool are also available.


Check-plagiarism.com claims that the reports on their site are highly inaccessible and secure.

The website includes a section with FAQs, although the answers may be unclear. Furthermore, they offer live messaging support and a contact form for further inquiries.

What is plagiarism?

Plagiarism can be defined simply as cheating. It involves copying someone else’s content and presenting it as your own. Using someone’s photo without permission or proper credit is an act of plagiarism. Similarly, taking text from a source and using it on your website without proper citation is also considered plagiarism.

In an academic setting, getting caught plagiarizing can result in expulsion and have long-term consequences for your plans. Plagiarizing content for your blog is not a form of flattery but is also illegal. Copying content for your website can lead to reports and the removal of your website.

Common Types of Plagiarism:

Verbatim plagiarism occurs when content is copied word-for-word without credit or citation.

Mosaic plagiarism involves taking content from multiple sources and combining them without proper credit or citation.

Global plagiarism: This type of plagiarism involves claiming someone else’s entire work as your own.

Self-plagiarism: It refers to the act of reusing your own previously submitted work without proper acknowledgment. It is also known as auto-plagiarism.

Accidental plagiarism: This happens when you unintentionally commit plagiarism by paraphrasing content without providing proper citations or credits.

As content plays a crucial role in SEO ranking and the competition is fierce, websites often strive to produce more content. However, this can lead to challenges in monitoring the content for plagiarism. Whether it’s intentional copying or a missed citation, plagiarism can be difficult to detect, especially when dealing with many articles. Fortunately, there are resources available, such as plagiarism checkers, that can simplify the task.

Choosing the Best Plagiarism Checkers

When selecting a plagiarism checker, consider whether you need a standalone plagiarism checker or a tool with additional features to improve your writing. Assess the tool’s user interface and learning curve to ensure it is user-friendly and efficient.

Additionally, consider the specific needs of your organization. While certain plagiarism checkers may work well for individual users, larger organizations may require different features and capabilities.

Evaluate the pricing plans, the number of users supported, and the integration with third-party applications. These factors will help you determine the best plagiarism checker that suits your requirements.
