AI that writes like a person.
Language models now draft a large share of the emails, messages and documents people send, and nearly all of it sounds the same. We’re building one that writes the way people do, and sounds like you when it writes for you.
Quick one about Thursday’s planning meeting. I’m at the dentist until two, so I’ll dial in. Want my numbers ahead of time?
Thanks, Priya
Better at answering. Worse at writing.
Language models get better every year at answering hard questions. Their writing hasn’t kept up, and in some ways it has slipped. Training them to be agreeable gave them one house voice, cheerful and careful, that hedges every claim and sums up what it said a paragraph ago.
You know the voice. It hopes this email finds you well. It delves. It calls things a testament, a tapestry, a game changer. People now spot it within a sentence, and once they do, they stop giving the writer the benefit of the doubt.
When everyone writes with the same model, everyone starts to sound like the same person.
Readers can tell in a sentence.
Machine-written text has habits, like opening with pleasantries, reaching for big words and wrapping up with a recap. Swapping in synonyms leaves those habits in place, so Ultri writes the piece again from what you meant.

It matters most in the writing you do every day.
Most of what people write is short and personal, like an email to a landlord or a note to a friend who is grieving. A stock phrase in those is the first thing the reader notices.
A language model that writes like a person.
We started with rewriting because that’s where people run into the problem today. Where we want to end up is a model whose first draft you’d send without editing.
- Today
Rewrite
Paste a draft, whether you wrote it or an AI tool did, and get it back sounding like a person wrote it.
- Next
Write
Tell Ultri what you need to say and who it’s for, and it writes the first draft itself.
- Later
Write like you
A model that learns how you write in particular, so what it drafts reads like you on a good day.
Using it today takes three steps.
Paste your draft
Anything from a short email to a few pages. It does best with 150 to 1,500 words.
Ultri rewrites it
It works out what you’re saying, then writes it again paragraph by paragraph, reading each one back before keeping it. This takes a few minutes.
Read it and send it
You get the new version with its score, and you can compare it with your original line by line before you copy it.
Know how it reads before anyone else does.
Each rewrite comes back with a score from a leading AI detector and a check against your original. If a point you made didn’t survive, Ultri lists it.
Questions people ask first.
Isn’t this just a paraphraser?
No. A paraphraser swaps words and keeps the machine’s structure, and the structure is what readers and detectors pick up on. Ultri works out what your piece says and writes it again from scratch, then checks the new version against yours.
Why not just ask a chatbot to sound more human?
You can try, but you’ll usually get the same voice with a few contractions added. Assistant models drift back to their house style within a paragraph because that’s how they were trained. Ultri uses writers that never learned that style, and it rereads every paragraph before keeping it.
How long does a rewrite take?
Usually three to ten minutes, depending on length, because Ultri writes several versions of each paragraph and keeps the best one. You can close the tab while it works and find the result in your account later.
Will it change what I meant?
It shouldn’t. Every rewrite is compared against your original, and the reading tells you if a main point went missing. If you need every number and name kept exactly, turn on “Keep every detail” in the options.
Can it sound like me specifically?
Partly. If you paste a few paragraphs you wrote yourself under “Sound like me”, Ultri copies things like your sentence length and how formal you are. A model that learns your voice properly is something we’re working on.
Is my writing private?
Your pieces are saved to your account so you can come back to them, and only you can see them. You can delete any piece at any time.
Writing should sound like someone wrote it.
