What does an AI detector percentage mean?
It differs by tool: GPTZero and Originality.ai report a confidence/probability about the whole text, while Turnitin reports the share of the submission flagged as AI (hiding scores under 20%). It almost never means "that percent of the words were AI-written", and scores are not comparable across tools.
