Rewrite & paraphrase · Paraphrasing tool
AI paraphrasing tool that keeps your meaning
Most paraphrasing tools have the same flaw: they swap synonyms until the meaning blurs and the sentences read awkwardly. You get something technically different that nobody would want to read.
Undetected.ai paraphrases the right way. It rewrites your text into fresh, natural prose that says exactly what you meant, with the rhythm a human reader expects. Because the paraphrase rebuilds sentences rather than swapping synonyms, our own AI-pattern score moves for a reason you can read on screen.
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 paraphrase AI text
Meaning-first paraphrasing
The rewrite expresses your point in fresh words without drifting from what you actually meant, so nothing important gets lost in translation.
Reads naturally
Output flows like real writing, with varied sentences and natural transitions, not the awkward synonym soup other paraphrasers produce.
Rebuilt, not reworded
Because the paraphrase rebuilds sentences instead of swapping synonyms, our AI-pattern score moves for a reason you can read.
What it handles
Natural prose, with the proof on screen
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.
