AI humanizer: humanize AI text so it reads like you wrote it
Paste your own text and get it back rewritten: natural, human-sounding prose that keeps your meaning, with our AI-pattern score measured on it before and after.
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 writers switch
An AI humanizer built around proof, not promises
Most humanizers hand back rewritten text and ask you to take the result on trust. Undetected.ai rewrites your own text, keeps your meaning intact, and shows our AI-pattern score before and after with the reasons behind it.
Rewrites the patterns that read as machine
One pass over your own text: the metronomic sentence rhythm, the template transitions, the agentless passive voice. It is your paragraph that comes back, rewritten, not a sample of somebody else's.
Our AI-pattern score, with its reasons
A gauge scores your text before and after on four things we can actually measure, and lists what pushed the number up. It is our own score, not a reading from GPTZero, Turnitin or any other detector.
Reads human, keeps your meaning
Natural rhythm and burstiness, your facts and argument intact. Undetected.ai rewrites the robotic patterns, not your point, so the output is prose a person would actually publish.
Writing that stops looking machine-made
Genuinely edited writing still gets flagged, because detectors read patterns rather than intent. Fixing the patterns is what you can control, and it is the part this tool does.
How to humanize AI text
From machine rhythm to your own voice in three steps
No prompt engineering, no manual rewriting. You paste the text and Undetected.ai rewrites it, with the AI-pattern score showing what moved.
Paste your AI-written text
Drop in a blog post, email, essay, or product copy. We measure it first and underline the template phrases we actually found in it.
Pick a tone and humanize
Choose Standard, Academic, Casual or SEO, set the strength, and humanize. Your text goes to the model and comes back rewritten.
Copy text that reads human
Get natural, human-sounding prose that keeps your meaning, with our AI-pattern score for the rewrite next to the score for the original.
Before and after
See the robotic tells rewritten into natural prose
This is the real output. The phrases detectors flag, the "Moreover," the "it is important to note that," the uniform rhythm, get rewritten into writing with the burstiness and voice of a person, while your meaning stays exactly where it was.
- Robotic transitions and filler phrases removed
- Natural sentence-length variation (real burstiness)
- Your facts, argument and structure kept intact
- Our AI-pattern score measured before and after
Moreover, it is important to note that consistency is the key to building an audience over time.
Consistency is what actually builds an audience. Show up, week after week, and it compounds.
We are excited to announce that our new collection is now available for purchase.
The new collection just dropped, and the first run never lasts long.
In conclusion, the evidence clearly demonstrates that the policy had a significant impact.
Taken together, the evidence makes the case hard to argue with: the policy changed things, and not at the margins.

Whatever you write, Undetected.ai makes it read human

Learn moreWhat the score measures
Our AI-pattern score, and how it is worked out
This is our own measurement, made here on your text. It is not a GPTZero, Turnitin, Originality.ai, Copyleaks or ZeroGPT result, and we do not claim it predicts one. Every point it gives back comes with the reason that earned it.
| Signal | What it looks at | Weight |
|---|---|---|
| Sentence rhythm | How much sentence length varies. Unedited model output holds a near-constant beat; people swing between short and long. | 35 points |
| Template phrases | "In conclusion", "It is important to note", "Moreover", "delve", "tapestry" and about sixty more, counted per hundred words. | 30 points |
| Vocabulary variety | Distinct words per fifty-word window, so the figure does not simply fall as a piece gets longer. | 20 points |
| Passive voice | An estimate of how many sentences are agentless. Reported as an estimate, because it is a heuristic and not a parse. | 15 points |
No tool can promise you a score from a detector it does not control, and detectors retrain constantly. What you get here is our own reading of your text, the reasons behind it, and the rewrite itself.
