How does GPTZero identify plagiarized content?

GPTZero’s plagiarism detection tool compares your inputted text to billions of webpages and academic papers found online. When you use GPTZero’s plagiarism check to detect plagiarism, it will give you a report of what % of your content is plagiarized and flags specific sentences and which sources they are from. Don’t worry - all text inputted to GPTZero is confidential and no one will have access to your scans.

Can it find unintentional plagiarism?

Unintentional plagiarism is, “not giving proper credit for someone else's ideas, research, or words, even if it was not intentional to present them as your own.” GPTZero’s sources section scans your text for similar matches found online. It will help tell you whether your text contains duplicate content and what sources the text was found from so you can properly cite your work.
