Features
AI humanizer features built around proof
Undetected.ai is not a thesaurus swap. It rewrites your AI text into natural, human-sounding prose, keeps your meaning, and shows our own AI-pattern score for the text before and after, with the reasons behind the number. Here is everything it does.
Our own score before and after
Your text meaning intact
The features in action
Every feature on screen at once
Paste your own text or load a sample, choose a tone and strength, and read the rewrite next to the original with our AI-pattern score on both.
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.

Everything in the humanizer
One tool that rewrites your text and shows its working
You paste AI text. Undetected.ai handles the rewrite, the AI-pattern score before and after, the reasons behind it, and the tone, then hands you prose ready to publish.
Live AI-pattern gauge
A semicircular gauge sweeps from the score we measured on your original to the score we measured on the rewrite. Both numbers are ours, computed on this server, and neither is a reading from an outside detector.
One pass over your own text
Your paragraph goes to the model and your paragraph comes back, rewritten. If the rewrite fails, you are told it failed. You are never shown a sample paragraph in place of your own.
The reasons behind the number
Under the score sits the list of what earned it: which template phrases were found in your text, how little the sentence lengths varied, how narrow the vocabulary was, how much of it was passive.
Meaning-preserving rewrites
Undetected.ai rewrites the robotic patterns, not your point. Your facts, argument, and structure stay intact, so the output is publishable prose, not word salad.
Four tones and a strength dial
Choose Standard, Academic, Casual, or SEO, and set how light or strong the rewrite is, so the output matches the piece you are working on.
Natural rhythm and burstiness
The rewrite restores varied sentence length and genuine transitions, the human rhythm detectors look for, instead of the flat, uniform cadence that gives AI text away.
Clears false AI flags
Even genuinely edited writing gets wrongly flagged. Undetected.ai restores natural variation so honest work reads as the human writing it is.
Works with any AI model
ChatGPT, Claude, Gemini, or anything else. Undetected.ai targets the shared patterns detectors flag, so any draft comes out reading human.
Your runs, your call
Every rewrite is saved to your account history so it is there when you come back, every one has a delete button, and anything older than 90 days is deleted automatically. The rewrite is produced by Google Gemini, and our privacy page says plainly what that means.
The signature feature
See the robotic tells rewritten, with the score to match
The phrases detectors flag, the "Moreover", the "it is important to note that", the uniform rhythm, get rewritten into natural prose, and the gauge shows what that did to our AI-pattern score.
- Robotic transitions and filler phrases removed
- Natural sentence-length variation, real burstiness
- Your facts, argument, and structure kept intact
- The score and its reasons, on your original and on the rewrite
Before, flagged as AI
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.
