What is Turnitin?

Turnitin is the academic integrity platform universities have used for decades to check student work against an enormous database of papers, journals and web content. Its similarity checker is the reference point for plagiarism in education, and the company has added AI-writing detection that estimates how much of a submission resembles text produced by large language models like ChatGPT.

Access is institutional: schools license Turnitin and students submit through their learning management system, so individuals generally cannot buy it directly. Instructors get similarity and AI reports inside their normal grading workflow. The AI indicator has attracted debate, because false positives can harm students, and Turnitin itself cautions that its percentage should support — never replace — an educator's judgement.
