AI Humanizer
Rewrite AI text in a human voice, then re-check it.
Paste AI-generated text, get a rewrite that reads like a person wrote it, and see the before and after score from our own AI detector.
How it works
Rewrite, score, repeat.
Paste the text
English text up to 1,000 words on a free account (5,000 on Pro). The counter shows where you stand against your limit.
Pick a mode and rewrite
Free mode works for everyone. Pro accounts can set a tone, turn the synonym strength up or down, or run three rewrites at once.
Read the before/after score
Signed-in rewrites are re-checked with our detector. You see the score of your source next to the score of the output, plus what changed.
Re-run or hand off
Still scoring high? Rewrite again with one click. Happy with it? Send the text to the detector, the citation checker or the grammar checker.
What the humanizer changes, and what it leaves alone
Text from ChatGPT, Claude or Gemini tends to share a rhythm: sentences of nearly the same length, a tidy transition at the start of each paragraph, stock vocabulary such as delve, tapestry and it is important to note, and a habit of hedging every claim. Those are the signals AI detectors score, and they are also what makes the writing feel machine-made to a reader.
The humanizer rewrites for those signals. It varies sentence length, swaps the stock phrases for plainer ones, cuts filler transitions and keeps contractions where a person would use them. It is instructed to keep the meaning, facts, names, numbers and paragraph order intact and to change only the style. The output view highlights every word that moved so you can check that nothing important drifted.
It does not inject the fake-casual filler that some rewriting tools add (honestly, here's the thing, let's be real). Detectors trained on humanizer output fingerprint those words, so adding them raises scores instead of lowering them.
Every signed-in rewrite is scored before and after
This is the part most humanizers skip. When you are signed in, the source text is scored by our own AI detector, the rewrite is scored again, and both numbers appear under the output. If the rewrite still reads as AI, the humanizer retries with the detector's notes about what it flagged, then shows you the best attempt. You can re-run it with one click, and Pro accounts can switch on Max Evasion for the strongest pass.
The rewrite model is chosen by how AI-like the source reads. A quick read of the input decides whether a lighter model is likely to produce an acceptable draft or whether the stronger model should take the first pass; a lighter draft that fails the re-check is escalated automatically. You see which mode produced the output in a small label under the text.
Does it beat AI detectors? An honest answer
No humanizer reliably beats every detector, including this one. Detectors differ in what they weigh, and the newer ones are trained on humanizer output, so they catch the tells rewriting leaves behind: odd synonym swaps, flattened rhythm, clipped sentences. We tested our own output against GPTZero, ZeroGPT and Pangram and published the results, misses included, in do AI humanizers work?. Read that before you rely on any score, ours or anyone else's.
The before/after number on this page comes from our detector and is one reading, not a verdict from Turnitin or your institution's tool. If you need to know how a specific detector reads the text, paste the output into it. The Check for AI handoff under the output sends the rewrite straight to our detector for sentence-level highlights.
The good use of a humanizer is making your own AI-assisted draft sound like you: notes you expanded with a model, a summary you asked for and want to publish in your voice, a translation that came out stiff. Passing off AI work where AI use is not allowed is a policy problem, and no rewrite fixes it.
Free, signed-in and Pro: what you actually get
Guest
- Up to 500 words
- Short preview of the rewrite
- Sign in (free) to get the full text
Free account
- Daily credits, one per rewrite
- 1,000 words per rewrite
- Before/after detector score
- Free mode
Pro
- 5,000 words per rewrite
- Six tone modes and the synonyms slider
- Ultra run: three scored rewrites
- Max Evasion mode
Guests see a short preview of the rewrite and sign in for the full text. Free accounts get daily credits and a 1,000-word cap per rewrite; Pro takes that to 5,000 words, adds the tone modes and the synonyms slider, and unlocks Ultra run and Max Evasion. Prices and the full comparison are on the pricing page.
Long documents are better rewritten in sections. The detector scores long files section by section for the same reason: one number for five thousand words hides where the AI-sounding passages actually are.
FAQ
AI humanizer questions, answered.
- Is the AI humanizer free?
- Partly. Without an account you can paste up to 500 words and see a short preview of the rewrite. A free account gets daily credits, a 1,000-word cap per rewrite and the before/after detector score. Pro raises the cap to 5,000 words and unlocks the tone modes, Ultra run and Max Evasion.
- Do I need to sign in?
- You can paste text and start a rewrite as a guest, but the full rewritten text needs a free account. Signing in is also what turns on the detector re-check, because that pass costs us a second model call per rewrite.
- Will the output pass AI detectors?
- Sometimes, and no tool can promise it. Every signed-in rewrite is scored by our own detector before and after, and the humanizer retries when the score stays high. Other detectors weigh different signals, so treat the score as one reading rather than a guarantee. We published our own test against GPTZero, ZeroGPT and Pangram rather than hide the misses.
- What is the word limit?
- 500 words for a guest preview, 1,000 words on a free account and 5,000 words on Pro. The counter under the input turns red when you are over, and a one-click trim cuts the text to the limit. Longer documents work best in sections anyway, because a single rewrite of thousands of words flattens the voice.
- Which model rewrites my text?
- It depends on how AI-like the source reads. A quick read of the input decides whether a lighter model drafts first or the stronger model takes the first pass; if a lighter draft fails the detector re-check, the stronger model takes over. Max Evasion always uses the stronger model.
- What do the modes and toggles do?
- Free mode is a general rewrite that keeps your register. Standard, Academic, Simple, Formal, Informal and Expand (Pro) set the register instead. The synonyms slider controls how much vocabulary changes. Ultra run returns three rewrites side by side, each scored. Max Evasion breaks up the machine-even rhythm and inserts a few deliberate typos, so proofread before you submit.
- Does it change facts, quotes or citations?
- The rewrite is instructed to keep the meaning, facts and structure and change only the style, and the before/after view shows every word that moved. Still read the result: any rewriting tool can drift, and if the text contains references, run the Check Citations handoff afterwards.
