Make it sound machine-made human.

Humanize is an editor for machine text. Paste what the AI gave you, pick a voice, and watch three passes go over the page — it reads for meaning, drafts fresh, polishes aloud, and strikes every tell on the way out. What comes back reads like a person wrote it, because structurally, one did the editing.

Paste up to 20,000 characters. Nothing to sign up for, nothing stored.

Three passes over the page

One prompt can't un-write a machine. An editing process can. Each pass has its own temperature — how loose the hand is — and the numbers below are the real ones.

1. Read for meaning

temp 0.2

The input is distilled to flat notes — just the facts, none of the phrasing. The rewriter never sees the original sentences, so it can't echo them. That's the anti-detection trick, and it's structural, not cosmetic.

2. Draft in a voice

temp 0.9

From those notes, a fresh draft in the voice you picked — its own rhythm, contractions, asides. Because it writes from notes rather than rewrites sentences, the prose has somewhere to go.

3. Polish aloud

temp 0.98

A final pass reads the draft back and loosens whatever still sounds typed. This one streams to your screen token by token — you watch the editor work.

The house style

After the model is done, a deterministic pass goes over the galley with the red pencil. No AI judgement involved — these marks are struck every time, by code.

Struck
— the em-dashthe most machine mark on the page
; the semicolonpeople mostly just start a new sentence
“Moreover,” “Furthermore,”nobody talks like this
“In conclusion,”the reader can tell it's concluding
“It's important to note”then just note it
Kept
^ Your factsthe notes pass keeps what you said, not how the machine said it
^ Your paragraphsoutput is shaped back to the source's paragraph count
^ Your lengtheach voice has its own length ratio — concise actually is

Five voices

Each voice is a full persona with its own length ratio — not an adjective bolted onto one prompt.
