Rewrite ChatGPT text

Paste a text that ChatGPT or another model wrote for you, pick its type and humanisation rewrites it so it stops sounding machine-made. Without signing in you get two rewrites per 30 days for texts up to 3,000 characters; a free account gives five humanisations per 30 days and longer texts.

How machine-like the text reads after the rewrite, by our own measure of sentence rhythm, AI phrases and repetition. 0 = natural, 100 = machine-like. It is not a detector score.

What happens to text from ChatGPT

Why ChatGPT text sounds machine-made

ChatGPT writes evenly: its sentences are of similar length, its paragraphs share the same structure and the text is held together by phrases like “in today's world”, “it is important to note” or “in conclusion”. A reader notices before reaching the end of the first paragraph.

It is not about mistakes; the text is usually grammatically fine. What reads as machine-made is the regularity itself — a person mixes short and long sentences, repeats a word for emphasis and steers clear of generic filler.

What the rewrite changes

Humanisation measures the text first: sentence rhythm, phrases typical of AI and repeated collocations. Then it rewrites the text to suit the chosen type, adds small human irregularities and measures the result again. Anything that fails a check is repaired once.

Facts, numbers, names, quotations and the order of ideas are meant to stay, and the length must not change by more than a quarter. The rewrite does not check factual accuracy automatically, though, so read the whole result.

What the rewrite does not change

Where the text comes from. Text from ChatGPT is still text from ChatGPT after the rewrite, just written differently. If the rules of your school, publisher or client require you to disclose AI use, the rewrite changes nothing about that.

Nor does it guarantee that the text passes a detector. Each detector measures something different, and detectors change. The machine feel shown above the text is our own measure of style, not a score from someone else's detector.

How to get the most out of the rewrite

Pick the right text type — an essay is rewritten differently from an e-mail or a cover letter. Rewrite a longer text in parts so it is easier to check.

With an account the rewrite also follows your sample texts, so it gets closer to how you write. The best result, though, comes when you add an example or an experience of your own to the rewritten text — no model can do that for you.

FAQ on rewriting ChatGPT text

Does it work on text from Claude or Gemini too?

Yes. Humanisation measures properties of the text, not which model wrote it, so it handles output from any AI chat.

Can people still tell ChatGPT wrote the text after the rewrite?

From the style it is harder, but you cannot be sure either way. Traces in the content remain — generic claims, no first-hand experience, made-up sources — and the rewrite does not fix those.

Can I submit the rewritten text as my own?

That depends on the rules. Where AI use has to be disclosed, the rewrite does not change that, and where AI is banned, the rewrite does not make the text allowed. If you are not sure, ask beforehand.

Does it work for Czech, Slovak or German text too?

Yes. Humanisation detects the language on its own and has its own list of phrases typical of AI and its own rewrite rules for each of the four languages.

Longer texts with a free account

Five humanisations per 30 days, texts up to 300,000 characters, the deep rewrite and analysis before and after. The account is free and needs no card.
