In their own words
Detecting-AI.com
Detecting-AI.com analyzes writing for signals associated with AI-generated text and presents a document score with highlighted passages. The web detector accepts pasted text plus TXT, PDF, and DOCX files; scanned PDFs requiring OCR are not supported. It is designed for text linked to GPT, Claude, and Gemini, including edited or AI-assisted drafts. The service preserves document structure, scores eligible sentences separately, and combines those scores into a document signal. The maker reports 99% detection accuracy and a false-positive rate under 1% on its described datasets, while noting that short, translated, heavily edited, or formulaic writing can be harder to classify and that a score cannot establish authorship or misconduct. Paid plans add unlimited AI detection, an AI Humanizer, Fact Checker, and plagiarism credits. REST APIs cover detection, humanization, and plagiarism checks, with a remote MCP server for compatible assistants. The free plan requires no account and allows 15,000 characters per check. Paid pricing starts at $7 a month billed annually.
