AI-Text Detection

Reason about AI-text detection as a defender. Learn statistical detectors (perplexity, log-likelihood), classifier detectors (GPTZero, the retired OpenAI text classifier, Originality.ai), the documented false-positive bias problem (especially for non-native English and formulaic writing), the policy stance many organisations have taken (do not use as ground truth for accusation), and the integration pattern that uses detection only as a hint, not an answer.
