The academic integrity standard used by 16,000+ institutions to catch plagiarism and AI writing.
Turnitin is not a consumer app — it is the backbone of academic integrity for universities, high schools, and scholarly publishers. In 2026 its AI-writing detection runs on the same similarity engine that has indexed billions of student papers since 1998. When a professor says "this got flagged by Turnitin," this is the system they mean. It is the highest-stakes detector in the world, which also makes its false-positive rate the most debated.
Who it's for: Universities, K-12 schools, and journals that need to screen student and manuscript submissions at scale.
The original plagiarism engine, matching submissions against the worlds largest student-paper corpus.
Flags likely AI-generated passages and shows an overall "AI likelihood" score.
Rubric-based grading and feedback tools bundled for instructors.
Deep integration with every major learning-management system out of the box.
Turnitin is the institutional default for a reason: unmatched source coverage and deep LMS integration. The AI detector is conservative by design (it under-flags rather than over-flag) to protect students. If you are an institution, it is effectively mandatory. If you are an individual student, you will meet it through your school — not by subscribing yourself.
