ABOUT TURNITIN
Turnitin is the odd entry in any consumer-facing detector list because
individuals cannot buy it: access comes through an institution, pricing is
quote-only, and there is no free tier to try. Its position rests on the
existing repository and LMS integration rather than on detection accuracy,
which is subject to the same false-positive limits as every other detector.
OVERVIEW
- Who is it for?
- Schools, colleges and universities running academic integrity processes, not individual students or writers.
- Problem
- Integrity decisions need to sit inside the grading workflow with an auditable record, which a standalone web checker cannot provide.
- Solution
- Turnitin delivers AI writing detection alongside its established similarity checking directly inside the LMS, so instructors see one report at the point of grading. It is sold to institutions on a quote basis with no public pricing and no free tier.
- What makes it unique
- The submission repository and LMS integration built over two decades - the detection is the newer part, and the institutional distribution is what makes it the default.
KEY FEATURES
- AI writing detection integrated into the submission workflow
- Similarity and plagiarism reporting against a large institutional repository
- Delivery inside existing LMS platforms
- Instructor-facing reports rather than a public checker
- Sold to institutions rather than individuals
COMPANY
- Publicly traded
- No
