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.

Key Features

AI detection score: Returns a clear overall score indicating how likely a passage was generated by an AI model, based on patterns like repeated phrasing and uniform rhythm.
File upload support: Accepts TXT, DOCX, PDF, and PowerPoint files, so long documents can be checked without copy-pasting.
Sentence-level highlights: Every flagged sentence is marked and individually scored, letting users locate AI-generated text without reading an entire draft.
Text humanization: After detection, flagged text can be rewritten in a more human tone to improve originality and natural flow.
Content comparison: Displays AI and human portions side by side so users can see at a glance which passages need revision.
Model selection: Offers a choice between a fast checker mode and a deeper detection model, letting users balance speed against detail.
Multilingual accuracy: The detection model is trained across multiple languages and supports essays, reports, and long documents.

Content creators and bloggers check drafts before publishing, while marketers review campaign copy, landing pages, and social posts for generic, machine-like wording.
