Turnitin AI writing detection

Waterloo discontinued Turnitin AI detection after internal tests and a cost review

StoppedCompany's own claimOfficial ↗

Problem

Waterloo used Turnitin's AI detection scores to help instructors identify possible prohibited AI use in student writing. The feature went live at the university on 6 April 2023.

Approach

Instructors received AI scores alongside Turnitin's existing originality reports, with warnings that a high score did not establish misconduct. Waterloo later said internal testing had repeatedly classified human writing as entirely AI-generated and had not established clear benefits. Citing expense, unreliability and research about bias against writers whose first language was not English, it discontinued the feature from September 2025. The university encouraged assessment redesign, AI literacy and academic integrity education.

Results

No published figures

Takeaway

Waterloo's internal testing did not establish that the detector delivered benefits worth its cost. Initial cautions about interpreting scores were followed by withdrawal of the feature.
