AI rewriter: an AI text rewriter that makes writing sound human
A good rewrite should improve how text reads, not just shuffle the words. Most rewriters do the shuffle, leaving you with awkward phrasing that still trips detectors and reads worse than the original.
Undetected.ai is a rewriter built around natural human rhythm. It reworks stiff or machine-made writing into prose that flows, and keeps your meaning exactly. Our own AI-pattern score, measured before and after, shows what the rewrite actually changed.
2 free runs a day, up to 200 words each. We save your run so you can get back to it, and a delete button appears with the result. See privacy.
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.

Our own score before and after
Your text meaning intact
Why it works
What you get when you rewrite AI text
Rewrites for rhythm
Sentence length, transitions, and phrasing are reworked into the natural variation that reads human, not a flat word swap.
Meaning protected
Your point, facts, and structure stay intact through the rewrite, so the output says what you meant in a better voice.
Aimed at the measurable part
The rewrite targets the patterns detectors actually score, and our own AI-pattern gauge shows what that did to the text.

You paste the text and pick a tone. Undetected.ai rewrites the robotic patterns, keeps your meaning, and shows our AI-pattern score before and after.

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.
