It is trusted by over 17 million users and 1 million educators globally, integrating with platforms like Google Docs and Canvas.
GPTZero offers a suite of features beyond basic AI detection. These include a hallucination detector, plagiarism checker, and writing feedback tools. For educators and institutions, it provides integrations with learning management systems and a "Writing Replay" feature that offers video proof of the writing process, showing copy-pastes and typing patterns. This granular detail helps in understanding AI usage and promoting responsible writing habits.
The tool is accessible through a free tier, offering 10,000 words per month and basic AI scans.
