Free AI humanizer that shows every change it makes.

It rewrites text that reads as machine-written so that it reads as a person's. Models have habits: stock phrases like "plays a crucial role", sentences that open with "Moreover," and "Furthermore,", tidy lists of three, no contractions, and sentences that all run to the same length. The humanizer takes those out, varies the rhythm and chooses plainer words, while keeping what the text says.

Ours also shows its work. Every change is marked in the rewrite, and a panel lists which patterns were in the original and how many remain.

Usually it scores much lower, and you can see for yourself: after a rewrite, use the check button to run both versions through our AI detector. But no humanizer can promise a pass. Detectors disagree with each other, they change over time, and some of what they measure is in the ideas rather than the wording.

The honest way to think about it: the rewrite removes the surface habits that give machine text away. Whether the result reads as yours depends on whether you make it yours, so read it and edit it.

It is not supposed to. The rewrite keeps every claim and the order they come in, along with names, numbers, dates, quotations, citations and paragraph breaks. It adds no facts, examples or conclusions.

It is still software doing the rewriting, so read the result before you use it. The marked changes make that quick: anything unmarked is unchanged.

Natural is the default and suits most writing: plain prose with contractions where they fall naturally. Casual is looser and more conversational, for blog posts, emails and social copy. Professional is clear and direct, for business writing. Academic keeps a formal register with no contractions, for essays and papers, while still fixing the rhythm and word choice.

It is free and needs no account. Each rewrite covers up to 600 words; longer text is cut to that length and the result says so. There is a daily allowance of rewrites per visitor, and on very busy days the per-rewrite limit may be lower. Trail, our full product, has no word or daily limits.

Yes. Upload a PDF, Word document (.docx), OpenDocument text (.odt), RTF, Markdown or plain text file, or paste the address of a public web page. Files are read in your browser; only the extracted text is sent to be rewritten.

Your text is sent to a third-party rewriting service to produce the rewrite and is not used to train models. We do not store the text or the rewrite: nothing is kept once the response has been sent to your browser. We keep only counts, such as how many words were rewritten today, to run the free allowance.

It depends on the rules you are working under. Editing your own AI-assisted draft so it reads like you is ordinary writing work, and this tool is built for that: it shows every change, so you stay in control of the text. Submitting machine-written work as your own where that is forbidden is a different matter, and a humanizer does not change that.

If you are a student or an employee, check what your institution or employer allows. Many now permit AI assistance with disclosure.

A paraphraser swaps words for synonyms and reorders clauses. That often makes text read worse, and it rarely touches the habits detectors look for, such as even sentence rhythm and connective openers. A humanizer edits for voice: it removes those habits specifically, varies the pace and prefers plain words, and it leaves wording alone where it already reads well.

It works best in English, where the pattern analysis (stock phrases, connective openers, contractions) applies. Text in other major languages is rewritten in the same language, but the before-and-after pattern counts cover sentence rhythm only.

Because a rewrite you cannot inspect is a rewrite you cannot trust. The marks tell you at a glance what moved, and the pattern panel tells you why. If a change is wrong, you can put the original wording back. If the rewrite barely changed anything, you know the text was already reading naturally.
