Claude wrote it. Make it read like you.

You can, and for one paragraph you probably should. The difference is that a chatbot rewrites once and hands you the result with no idea whether it worked. It cannot mark its own homework.

Here each paragraph gets several different versions, and one is kept only if it passes about a dozen quality checks: meaning, figures and names intact, not cut off mid-sentence, no leaked model chatter, not turned into a bulleted list, none of the roughly fifty banned AI clichés. If none passes, you get your original back rather than a confident-sounding substitute.

Writing you are entitled to send that happens to read like a model: reports, proposals, marketing copy, client-facing email, and drafts written in a second language that came back fluent but not yours.

It is not for passing off work in a setting where using a model is not allowed. If you are somewhere a model is not permitted, rewriting the output does not change that, it only makes the problem harder to see, and we would rather say so here than let you find out later.

It keeps your claims, your figures, your names and the structure of the argument. It changes sentence rhythm, hedging, and the phrasing a reader recognises as AI.

Names and figures are swapped for placeholders before the rewrite and restored afterwards, so the real ones are never part of what gets rewritten. If a figure comes back altered, that paragraph is discarded and your original kept. There is also a final check for whether the rewrite drifted so far it lost the meaning; if it did, it is reverted.

Read the result anyway. That is the one step no tool does for you.

It is the likelihood that writing reads as machine-made, from 0 to 100%. Lower is more human. Below 35% is clear, 35% to 70% is flagged, above 70% is strongly machine-like. You get a number for the document and one for each paragraph.

It is a probability, not a verdict. People who write in a regular, uniform style score higher than they deserve. Short paragraphs are the known weak spot: news-style and punchy marketing copy score far too high, and genuinely human-written news articles have scored around 99%. False positives are possible and we have seen them. The scores are also not calibrated, so 90% is a raw model output, not a claim that 90 of 100 such texts were machine-written. Never use this as sole evidence in a decision about a person.

No, and we won't claim otherwise. It is an editor for readability and voice, and it makes no claim about how Turnitin, GPTZero, Originality.ai or any other detector will read the result.

No rewriting service can promise you a third party's verdict. Anyone who does is guessing.

Drafts from Claude, GPT-5, Gemini and 40+ other models, plus text written before any of this existed. Paste it, or upload PDF, DOCX or TXT once you have an account. The free demo takes 1,000 characters.

About 50 seconds for a typical five-paragraph document, two minutes at the outside.

Formal and academic writing is the hard case. Tone drift is the known risk there, which is why the formality of your source is identified first and the rewrite is held inside it.

The demo is free and needs no account. After that it is $9.90 a month or $99 a year, which is the same plan billed differently: unlimited detections, 5,000 Humanizer words a month, uploads, priority support and exportable reports on both. If you use up the words, you can buy more without changing plan. Cancel whenever.

The text you submit and the rewritten result are saved, including free demo runs, and with an account they appear in your history so you can reopen them. It is never used for training, and never sold or shared. Detection runs inside our own service, so scored text does not go to an outside company at all. Data is encrypted in transit and at rest.

The service is operated by Girema Holdings Limited, a company registered in Limassol, Cyprus, so it sits under EU data protection law: you can ask for a copy of your data, a correction, or its deletion at any time. Payments are handled by Stripe and card details never touch our servers. The full detail is in our privacy policy.
