MyDetector
MyDetector is a free online AI detector that scans text and uploaded documents for AI-generated content from models like ChatGPT, Gemini, and Claude.
About
MyDetector is a web-based AI detection tool that estimates whether a piece of writing was produced by a person or a language model such as ChatGPT, Gemini, or Claude. It addresses a growing need among teachers, editors, marketers, and professionals to verify the origin of text before publishing, grading, or sharing it. Users can paste text directly or upload files in TXT, DOCX, PDF, or PPT format, and the tool analyzes style, structure, and wording patterns typical of machine output. Beyond detection, MyDetector includes a text humanization feature that rewrites flagged passages in a more natural tone, along with sentence-level highlights and a comparison view that separates AI-written and human-written portions. The service is offered free of charge online, with a daily usage limit.
