Undetectable AI

Undetectable AI is a text-analysis platform built around two connected tools: an AI Detector that scans a piece of writing and flags the sections most likely to have been written by an AI model, and an AI Humanizer that rewrites those flagged passages by varying sentence structure, vocabulary, and tone so the text reads as human-written. The detector and humanizer are designed to be used together, letting a writer check a draft, see what specific sentences are triggering AI-detection tools, and then selectively rewrite only those parts rather than the whole document. The platform's primary language is English, with secondary support for more than 60 additional languages, including Spanish, French, German, Chinese, Japanese, and Arabic, and typical processing takes about 10 to 30 seconds per document.

Beyond text, Undetectable AI offers an AI Image Detector and AI Audio Detector for checking whether visual or voice content is AI-generated, a Fake PDF Detector for spotting edited or AI-produced documents, a standalone sentence rewriter for paraphrasing specific passages, and a Chrome extension that brings detection and humanizing into Google Docs, Gmail, and other webpages directly. It also includes an AI Job Applier tool aimed at job seekers. Paid plans are billed by monthly word volume, starting around 10,000 words a month and scaling up to custom business plans with non-expiring credits and white-labeling for agencies. The platform is aimed at students and educators, content writers and bloggers, and marketing, SEO, and research professionals who need to review or adjust AI-assisted writing before publishing it.
