GPTZero AI
Uncover AI-written text with precision and ease.
What is GPTZero AI?
GPTZero is a detection tool designed to identify text generated by large language models like ChatGPT, GPT-4, and other AI writing systems. It analyses submitted text and provides a confidence score indicating the likelihood of AI authorship. The tool works by examining linguistic patterns and statistical features that distinguish machine-generated content from human writing. GPTZero is used by educators checking student work, content creators verifying originality, and organisations monitoring for AI-generated material in their workflows. The free availability makes it accessible for individual use, though results may vary depending on the AI model used to generate the text and how recently the detection algorithms were updated.
