AI Undetectable: AI humanizer and AI content detector

About AI Undetectable

AI Undetectable is an AI humanizer. You paste an AI-written draft of up to 750 words, choose a writing mode (general, essay, article, marketing or story) and a rewrite depth, and it rewrites the structure, rhythm and phrasing while keeping the meaning. Basic does one structural rewrite; Stealth runs a deeper reconstruction. The same site offers an AI text detector and an AI image detector.

It is built and marketed around getting past AI detectors. The pricing page offers a money-back guarantee: if anything it produces is flagged as not human, the cost of that rewrite is refunded. That is a clear statement of purpose, and it is worth being plain about the other side: in schools, universities and many publications, submitting AI-written work as your own breaks the rules whether or not a detector catches it.

You need a plan to humanize text. Every plan starts with a three-day trial. Credits are counted per input word: Basic uses one credit a word and Stealth two. The pricing page lists 10,000 credits a month for $9.99, 20,000 for $19 and 35,000 for $31, or about half that per month billed yearly. The largest plan adds unlimited detector checks and API access. It supports five languages.
