Copyleaks AI Content Detector
Checks text on web pages for signs it was produced by an AI chatbot rather than a person, useful for teachers, editors and readers.
Chrome extension
Checks text for AI-generated writing, verifies citations and replays how a Google Doc was written, aimed at teachers and students.
GPTZero brings AI-writing detection, writing feedback and citation checks into Google Docs and other places you work in Chrome. It is built mainly for teachers, students and researchers who want to understand how a piece of writing was produced.
Open a Google Doc after installing and use the GPTZero panel to run detection, view the writing replay or check citations.
AI detection results are estimates rather than proof and should be weighed with other evidence. Document text is sent to GPTZero's service for analysis.
