Paste an AI draft and get it back reading like a person wrote it: cliches cut, sentence rhythm varied, every fact kept. 5,000 characters per go, no account, free.
AI drafts have a recognisable sound: every sentence the same length, "in today's fast-paced world", "it is important to note", "leverage", "unlock". The rewrite cuts that — filler goes, buzzwords become plain words, sentence length starts to vary — while every factual claim, name and number stays exactly what it was.
The result is a draft that reads like a person on a good day: shorter, plainer, less padded. It works in the language you paste; major languages all come back in kind.
Want the wording changed but the tone kept? That's the paraphrasing tool — same engine, different instruction.
Most tools in this category sell one thing: "undetectable by AI detectors". We don't, on purpose. Detectors are unreliable in both directions — they flag human writing as AI and let AI writing through — so a guarantee against them would be a promise nobody can keep. If a tool sells you "guaranteed undetectable", ask how they'd ever prove it.
What we can promise: the text gets measurably plainer and more varied, the facts stay put, and you read the result before you use it. It's a rewrite tool, not a disguise.
The best-known paraphraser gives you 125 words at a time, six times a day, on the free plan. That is a demo, not a tool.
Here it's 5,000 characters per go — a few pages — and you can run one go after another. The rewriting runs on our own hardware, which is why we don't have to meter it word by word. There's an hourly cap per connection purely to keep scripts from hogging the queue; a person editing an essay won't hit it.
Your text goes to our own machine in the Netherlands, gets rewritten there by an open-source language model we run ourselves, and comes straight back. It is not sent to a third-party API, not stored, not logged and not used to train anything. When the response reaches your browser, the server has already let it go.
Yes. No account, no word credits, no daily cap. 5,000 characters per go, and an hourly cap per connection that a person editing by hand won't reach. Ads pay for the hardware.
We don't promise that, deliberately. Detectors misfire in both directions, so "guaranteed undetectable" is a claim nobody can back up. What you get is text that genuinely reads more naturally — judge it by reading it.
No. Keeping every claim, name and number is part of the instruction, and in our tests dates, figures and names came through exactly. Still — read before you publish; it's a rewrite, not a fact-checker.
Paste in a major language and the rewrite comes back in that language. English gets the most polish; Spanish, German, French, Dutch, Portuguese and the other big ones work well.
No. It's processed on our own hardware, not sent to any third-party API, and nothing is kept after the response is sent.
Same engine, different instruction. The humanizer changes the style — cuts filler, varies rhythm. The paraphraser keeps your tone and changes the wording.
Yes, in 5,000-character parts. Run them one after another; there's no daily cap.
