Turnitin AI Detection
Turnitin’s AI Writing Report is the most widely deployed AI detection layer in Canadian K-12, CEGEP, and university classrooms. Since the 2023 launch, its scoring methodology, accuracy claims, and integration into existing integrity workflows have been the focus of constant testing on this forum. Threads here cover real-classroom accuracy data, false-positive cases, comparisons against alternatives like GPTZero and Originality.ai, and the limits of what the Turnitin score can actually prove.
