DetectGPT

Externo

DetectGPT is a Stanford-developed zero-shot tool that detects AI-generated text by analyzing the curvature of a language model's log probability function through text perturbations, achieving up to 95% accuracy across benchmarks without retraining. It stands out for providing a training-free method to combat AI misuse in education, journalism, and content creation, where distinguishing human from machine writing is increasingly vital. This makes it valuable for researchers, developers, and casual users needing quick, scalable detection over supervised alternatives.
