What Detecting-AI.com is
Detecting-AI.com analyzes writing for signals associated with AI and shows a document score with highlighted passages. Its web detector accepts pasted text and TXT, PDF, or DOCX files; scanned PDFs that need OCR are not supported. It is designed to review text associated with GPT, Claude, and Gemini, including drafts edited by people or produced with AI assistance. The service scores eligible sentences separately and combines them into a document-level signal while preserving document structure. The 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 free plan costs nothing, needs no account, and allows 15,000 characters per check and up to 300 detections per day. Yearly costs $7 a month billed annually; Monthly costs $14 a month billed monthly. Paid plans include unlimited AI detection, humanization, and fact checking, with different limits and plagiarism credits. REST APIs support detection, humanization, and plagiarism checks.
Who it suits
It may suit educators, editors, publishers, and individuals reviewing text, provided they treat the score as a signal rather than proof of authorship. API and integration options may also suit institutions seeking scoped deployments or compatible workflows.
