Is QuillBot Plagiarism Checker Accurate?

Since its launch in 2017, Quillbot has gained recognition for offering a range of editing tools designed to enhance the quality of academic and professional writing.

Among these tools, Quillbot’s plagiarism checker feature stands out as a significant addition aimed at ensuring the originality of content.

This article gives you a useful insight to figure out “Is QuillBot plagiarism checker accurate?” and know the cost-effectiveness of QuillBot’s plagiarism checker, providing insights into its reliability for users.

Is QuillBot Plagiarism Checker Accurate?

Quillbot’s plagiarism checker is engineered to scan texts against a vast database of sources, including academic papers, web pages, and publications, to identify potential instances of plagiarism.

The tool uses advanced algorithms to detect exact matches and paraphrased content, ensuring a comprehensive review of the submitted text.

Users have reported high levels of accuracy in the detection of plagiarised content, highlighting the tool’s effectiveness in identifying copied material, even when it has been significantly altered.


In terms of data security, Quillbot ensures the confidentiality and protection of the documents checked through its system. The platform employs robust security measures to prevent unauthorised access to the submitted content.

Users can trust that their documents are handled securely, with no risk of them being stored or used without permission. This commitment to privacy and security makes Quillbot a reliable choice for sensitive academic and professional work.


Quillbot offers both free and premium versions of its plagiarism checker. The free version provides basic plagiarism checking capabilities, suitable for casual or less frequent needs.

However, for more in-depth analysis and additional features, such as a higher word limit per check and a more detailed report, the premium version is recommended.

While the premium service comes with a subscription fee, its comprehensive features and high accuracy make it a worthwhile investment for students, academics, and professionals seeking to ensure the originality of their work.

How Good is Quillbot Plagiarism Checker? 

QuillBot is a website that offers various tools for writing, such as paraphrasing, summarising, grammar checker, and plagiarism detector.

The plagiarism checker is one of the features that requires a premium subscription, which allows you to scan up to 100 pages per month for potential plagiarism in more than 100 languages.

The plagiarism checker analyses your text and compares it with sources on the web or in books, research papers, academic papers, or news sources.

It provides you with a plagiarism score and a report that shows you the sections of your text that need proper citations and the relevant original source links.

According to some reviews, QuillBot’s plagiarism checker is good for detecting plagiarism and providing clear and actionable feedback.

However, some users have also reported that it is not very accurate, fast, or user-friendly compared to other plagiarism checkers. Some of the drawbacks of QuillBot’s plagiarism checker are:

  • It does not detect all types of plagiarism, such as paraphrasing or AI-generated content.
  • It has a limit of 250 words per page, which means you may need to split your document into smaller chunks to scan it.

Therefore, QuillBot’s plagiarism checker may be good for some basic plagiarism checking, but it may not be the best option for more advanced or professional needs.

Quillbot’s plagiarism checker is a sophisticated writing tool that offers a comprehensive suite of benefits for a diverse range of users, from academic researchers and professional writers to content creators and students.
