FAQs About AI and Plagiarism Checkers

What is a plagiarism checker?

A plagiarism checker is a tool or platform that can scan your content to identify how similar it is to other content that has already been published, such as in previously published content appearing in web search results.

How do plagiarism checkers work?

Plagiarism checkers work by comparing the text that you input with websites, articles, or publications to identify any similarities in wording, structure, and phrasing to previously published content. 

For each match found, a plagiarism checker will typically highlight it and provide you with a percentage score of how much of the content is getting flagged as similar.

Keep in mind that not all plagiarism checkers work in the same way. While some scan academic databases others specialize in web-search based plagiarism detection. Learn more in our guide on types of plagiarism detection.
