The tool is aimed at writers, educators, and professionals who need to verify originality before publishing or submitting content.

The user experience centers on a straightforward dashboard where uploaded files are checked automatically. There is no mention of an account or payment requirement, positioning it as an accessible starting point for quick content verification. However, users looking for advanced collaboration, API access, or desktop applications may need to combine it with additional tools.

MyDetector AI is a free online AI content detector that identifies text generated by ChatGPT, Gemini, Claude, and other popular AI writing and paraphrasing tools.
