Undetected.ai

Humanize AI text · AI humanizer online

AI humanizer online that runs right in your browser

An online humanizer should just work the moment you open the page. No download, no plugin, no account before you have seen a single result. You paste your text, you watch it change, you copy it.

Undetected.ai is an AI humanizer online from start to finish. It runs in your browser, rewrites AI-generated text into natural prose, and animates our own AI-pattern gauge from the score on your draft to the score on the rewrite before you copy a word.

AI-pattern score

This is our own AI-pattern score, measured here on sentence rhythm, template phrases, vocabulary variety and passive voice. It is not a GPTZero, Turnitin, Originality.ai, Copyleaks or ZeroGPT result, and it does not predict one. Worth knowing: we also ask the rewrite to vary sentence length, drop template phrases and prefer the active voice, so some of the drop is built in. Read the two panels below, not just the number.

Why Undetected.ai

Readable output, and the measurement in view

Not word-salad that beats one scanner and reads worse. Natural prose that keeps your meaning, rebuilt sentence by sentence.

Our AI-pattern score, before and after

Four measured signals (sentence rhythm, template phrases, vocabulary variety and passive voice) scored on your draft and on the rewrite, with the reasons behind each number. It is our own measure, not a GPTZero, Turnitin, Originality.ai, Copyleaks or ZeroGPT reading, and we have no access to those services.

See the score change

The gauge animates from our AI-pattern score for your original to the score for the rewrite, with the reasons behind both numbers.

Keeps your meaning

Your facts, argument, and structure stay intact. Undetected.ai rewrites the robotic rhythm, not your point, so the output is publishable as is.
