DETECTING-AI.COM
AI Detector for ChatGPT, GPT-5, Claude and Gemini
DETECTING-AI.COM is a web-based AI detector that estimates whether text was written by a human or generated by AI. Users paste text or upload TXT, PDF or DOCX files to receive an overall AI score with sentence-level highlights showing which passages contributed to the result. No account is required for free scans. The service also offers an AI Humanizer, a Fact Checker, plagiarism checking, an AI-detection API and an MCP server.
The detector preserves document structure, scores sentences independently and averages them into a document signal. It is designed to review text from GPT, Claude and Gemini model families, including edited or mixed drafts. The AI Humanizer rewrites AI text, the Fact Checker checks factual claims, and plagiarism checking is available on paid plans. The AI Detector API and MCP server expose the same detection capabilities programmatically.
The service is aimed at education, editorial review, publishing, personal writing and developers. A free plan covers occasional checks without an account. Paid plans are available monthly or yearly, with unlimited AI detection, larger document capacity, plagiarism credits, unlimited humanization and premium support.
