The AI text humanizer
AI drafts are fine until someone reads them. The sentences are all the same length, the register never slips, and every cover letter opens the same way. Paste yours in and get it back sounding like a person — and see exactly what gave it away.
Up to 6,000 characters. Tell it what the text is — a cover letter and an Instagram caption need different rewrites.

Read it before you send it. Your name is on this, so fix anything that is not true of you and put back the one specific detail only you know.
Writing something specific? There is a page for it, with the tool already set to that text type and a real before-and-after: all 100 text types →
What actually gives it away
Readers rarely think “a machine wrote this”. They think “this is boilerplate” and stop reading. These are the four things they are reacting to, and they are all fixable.
Human writing lurches. A long sentence, then four words. AI drafts hold a steady fourteen-to-twenty-word rhythm for six paragraphs, and that evenness is what reads as machinery.
Real formal writing has one plain word in it. Real casual writing has one precise word in it. That mixing is the strongest human signal there is, and AI drafts almost never have it.
“I am writing to express my strong interest.” “In today’s fast-paced landscape.” “In conclusion.” Each one costs you the reader’s attention at the exact moment you had it.
A person leads with the useful bit. AI leads with setup, then context, then finally the thing you needed, arranged in whatever order the information arrived.
How it works
Whatever you have — a cover letter, a client email, a product description. Up to about 6,000 characters at a time.
Pick the text type and a tone. A cover letter and an Instagram caption need different rewrites, so the instruction changes with your choice.
You get the rewrite plus a short writing-insights panel: the specific things that were changed and one tip you can apply yourself next time.
What it will not do. It will not invent the specific detail that makes your writing yours — the project you actually shipped, the thing your interviewer said, the reason you want this. It cannot know those. It rewrites what you give it and keeps every fact intact, which means a vague draft comes back as a natural-sounding vague draft. Read the rewrite, then put the specifics back in.
By text type
A recruiter, a client and your landlord notice completely different things. Each of these pages has the tool pre-set, the specific giveaway for that kind of writing, and a before-and-after we wrote by hand.
FAQ
It rewrites the sentences: it varies their length, cuts the buzzwords and the stock openers, and puts the point where a person would put it. Every fact in your draft stays in the rewrite.
Yes — you get 5 humanizes a day in the browser with no account and no card. If you need more than that, MonkeyPen Pro is $5/month or $40/year.
It should not. The instruction we send is to keep every fact and the same meaning and only change how it reads. Always read the rewrite before you send it — you are the author, it is your name on it.
No. Your text is sent to the model to be rewritten and returned to your browser. We do not store it, and there is no account for it to be attached to.
Because it is averaged. Even sentence lengths, a formal register that never slips, stock openers like "I am writing to express", and a tidy summary at the end. Readers notice the pattern long before they can name it.
No. Read it, fix anything that is not true of you, and put back the one specific detail only you know. A rewrite gets you a natural draft; the specifics are what make it yours.
