Paste your draft to get started.

How it works

Three steps, and you see the evidence at every one. No guessing whether the tool changed your meaning.

Diagnose

Paste your draft and get an instant Humanity Score, a sentence-rhythm chart, and every AI pattern highlighted — free, in your browser.

Rewrite

Pick a voice by comparing real previews of your own text, then humanize the whole draft in one pass.

Verify

See the score climb, a word-level diff of every change, and a Fact-Lock report proving your names, numbers and quotes survived untouched.

Three drafts, three voices. Same ideas, same facts — just natural English.

What we never change

The rewrite touches phrasing, never your facts. Fact-Lock finds and protects:

  • Names
  • Numbers
  • Dates
  • Quotes
  • Links

An honest note

No tool — ours included — can prove whether a text was written by a machine. So instead of chasing detector scores, we focus on something real: writing that reads naturally, in your own voice, with every change shown to you.

Questions

Can I get a refund?

You’re charged only for paragraphs we deliver. If a paragraph fails, it costs nothing. Credits are pay-as-you-go and never expire.

What if my meaning changes?

Fact-Lock protects your names, numbers, dates, quotes and links, and every rewrite ships with a word-level diff. If a paragraph isn’t right, keep the original — per paragraph.

Is my text stored?

The free diagnosis runs entirely in your browser — your draft never leaves your device. When you humanize, text is sent only to perform the rewrite; it is never stored without an account and never used for training.

What languages does it work with?

formatkno works on English drafts today. It’s built for writers working in their second language — drafting from your first language is on the roadmap.

Can I humanize again?

Yes. You can retouch individual paragraphs as many times as you like — and you’re only ever charged for the paragraphs actually delivered.
