AI Humanizer humanize AI text so it reads like you wrote it
Paste your text and get it back rewritten in natural, human-sounding prose that keeps your meaning, with our AI-pattern score before and after.
What 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.
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.

Step 1
It is important to note that it brought about many changes. Moreover, it led to the rise of factories.

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.
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.
