Use tool ↗About Turnitin
Turnitin compares submitted student work against publications, web content and prior submissions and reports similarity, and since 2023 adds a separate indicator estimating how much of a document was machine-written. The line now spans Feedback Studio for grading and originality, Gradescope for paper-based and STEM assessment, ExamSoft for secure offline exams, iThenticate for publishers and researchers, and Clarity, a 2026 writing-analytics layer that tracks how a draft was produced instead of only flagging it. Products plug into Canvas, Moodle, Blackboard and D2L through LTI. It is sold to institutions on quoted licences after a sales consultation; Turnitin, LLC has served education since 1998 from Oakland, California and has been part of Advance since 2019.

Pros & cons of Turnitin
The incumbent for a reason: the submission database and the LMS integrations are what institutions buy, and no challenger matches either. Treat the AI-writing indicator as a prompt for a conversation, not a verdict; Turnitin itself now sells Clarity to show how a draft was written because a percentage alone keeps producing disputes, and the price only arrives after a sales call.
Pros
- Largest comparison corpus of prior student submissions, which web-only checkers lack
- LTI integrations with the major learning management systems
- One contract covers grading, originality, exams and manuscript screening
- Clarity adds process evidence about how a draft was written, not just a flag
Cons
- No public pricing; every deal is an institutional quote
- AI-writing detection produces false positives and has been contested by students
- Student papers feed the comparison database, a long-running data-rights objection
- The public site refuses automated fetches, which complicates monitoring
Best for
- Universities and school districts that need similarity checking wired into Canvas, Moodle, Blackboard or D2L
- Publishers and research offices screening manuscripts through iThenticate
- Assessment teams that want grading, proctored exams and integrity from one vendor
Not for
- Individual students or freelancers, who cannot buy a licence directly
- Anyone who needs the AI-writing score to stand as proof on its own
Watch out: The AI indicator is an estimate the vendor itself hedges; a policy that treats it as evidence will generate appeals, so budget for review workflows, not just the licence.
