Voice Profiles · the reason Timbro exists
Every other tool rewrites AI into a human voice — the same one, for everybody who buys it. This is the part that took longest to get right, and it is the part nobody else has: Timbro measures how you write and aims at that instead.
You have to see it on your own writing to believe it.
Your real writing
Your Voice Profile
Every AI draft, rewritten toward it
A Voice Profile is built from a real sample — an essay, an email, a post. Timbro measures durable things: how long your sentences run and how much they vary, how you connect ideas, how you punctuate, how your paragraphs open and close. Those measurements become the target when it rewrites.
It describes your writing, not you.
Start with something you wrote.
Around 900 words across two or three pieces gives a match you will recognise. Fewer than that still works — the profile just tells you it is a rough sketch rather than pretending otherwise.
Included with every paid plan, from $15 a month.
Something from ChatGPT, Claude, or anywhere else.
Natural works straight away. Write Like Me uses your Voice Profile.
Rewritten, saying exactly what the draft said.
7 modes. Six rewrite toward a general register, the way every tool in this category does. One aims at your own writing, which no other tool sells.
Numbers, dates, quotations and citations are checked against your original after the rewrite.
Original — generic AI
Moreover, the implementation of flexible working arrangements represents a significant development in organisational strategy. Additionally, the trial demonstrated that a reduction in scheduled hours does not necessarily result in a corresponding reduction in output. It is important to note that productivity remained stable while self-reported stress declined from 45% to 38% (Haar, 2018).

Flexible work changed how the team operated, but the interesting part was that output didn't fall. Cutting scheduled hours didn't cut what got done. Productivity held steady, and self-reported stress fell from 45% to 38% (Haar, 2018).
No Voice Profile. The rewrite engine on its own.

Here's the part I keep coming back to: they cut the hours and the work still got done. Flexible working changed how the team operated, sure — but output held. Productivity stayed flat, and self-reported stress dropped from 45% to 38% (Haar, 2018).
The same engine, aimed at a Voice Profile built from informal, argumentative writing.

Every figure survives all three: 45%, 38% and the citation (Haar, 2018). They are pulled out of the draft beforehand and compared against the result afterwards, in both directions — so an invented figure is caught as well as a dropped one. How that works.
Questions
You paste in writing an AI produced and Timbro rewrites it — structure, rhythm and phrasing, not just synonyms — so it reads like a person wrote it. It works on drafts from ChatGPT, Claude, or anywhere else.
Give it a Voice Profile built from your own writing and it aims at your style specifically rather than at good prose in general.
Yes. Rewriting needs one, and a new account gets 3 free rewrites of up to 2,400 characters — no card. It is how your history and your Voice Profile have somewhere to live, and it is what keeps the trial a trial rather than something anyone can reset by reconnecting.
Not to start. 6 of the 7 modes rewrite toward a general register and need nothing from you but the draft; your free rewrites run Natural and Student, and a subscription unlocks the rest.
But it is the thing worth paying for. Every other tool rewrites AI into one generic human voice; a Voice Profile makes the result yours rather than merely better, and it is the only part of Timbro nobody else sells.
Give it writing you have already done — an essay, an email, a post. Timbro measures durable habits: sentence length and how much it varies, how you connect ideas, how you punctuate, how paragraphs open.
Those measurements become targets when it rewrites. Around 900 words gives a match you will recognise; with fewer, the profile tells you it is a rough sketch rather than pretending otherwise.
Every number, date, quotation, citation and link is pulled out of your draft and compared against the result afterwards, in both directions — so an invented figure is caught as well as a dropped one.
It is a check rather than a proof, so your original stays beside the rewrite with a diff between them. Nothing is accepted on your behalf.
Your draft goes to the model that rewrites it, and nowhere else. It is never used to train anything, never sold, and the text itself is never written to a log.
You can delete a rewrite, a sample, a profile or the whole account at any time.
