GPTZero is an AI content detection platform that analyzes text to determine the probability it was generated by AI models including ChatGPT, Claude, Gemini, and other language models. It provides sentence-level highlighting showing which specific sentences are most likely AI-generated, along with a document-level probability score. Educators, academic integrity officers, and editors use GPTZero to identify potentially AI-generated submissions and writing. The API allows integration into learning management systems, plagiarism detection tools, and editorial workflows. GPTZero has become one of the most widely used AI detection tools in academic settings, though the entire AI detection field grapples with accuracy challenges: false positives (flagging human-written text as AI) are a persistent problem that has generated significant controversy when used for high-stakes academic integrity decisions.

What the community says

Educators on Reddit have mixed views: some appreciate having a detection tool, while teachers and students frequently report false positives that have caused significant problems for students who wrote their own work. The broader AI detection space is viewed skeptically for high-stakes decisions. Based on community discussions from Reddit.
