AI Detection
AI detection tools claim to identify text generated by large language models, and Canadian teachers increasingly rely on them to flag suspect student submissions. The leading detectors include Turnitin, GPTZero, Originality.ai, Copyleaks, and Grammarly, but accuracy varies sharply across tools, languages, and student profiles. The educators on this forum have documented how these tools behave in real classrooms, where they break down, and how to use them responsibly without unfairly accusing students.
