What Detecting-AI.com is
Detecting-AI.com analyzes writing for signals associated with AI and displays a document score with likely AI-related passages highlighted in the text. The web detector accepts pasted text and TXT, PDF, or DOCX files; it does not yet support scanned PDFs that need OCR. It is designed to review writing associated with GPT, Claude, and Gemini, including drafts edited by people or made with AI assistance. The service keeps document structure, scores eligible sentences separately, and averages those scores into a document-level signal. Its maker reports 99% detection accuracy and a false-positive rate below 1%, while noting that short, translated, heavily edited, or formulaic writing may be harder to classify. A score alone cannot establish authorship or misconduct. The service also offers API-based detection, humanization, and plagiarism checks, as well as a remote MCP server for compatible assistants. The free plan requires no account and supports checks up to 15,000 characters, with up to 300 detections per day.

Who it suits
It may suit educators, editors, publishers, and individuals reviewing text for AI-writing signals. Users who need OCR for scanned PDFs or a definitive authorship judgment should note the stated limits.
Verdict
Detecting-AI.com provides text scoring and passage highlights, with API options for detection and related checks. Treat its score as a signal rather than proof, especially for writing types the maker says can be harder to classify.
