Write with a tool that works really hard to keep your words yours.
A quiet, focused editor for writing — not word processing. The palette on the left, the page in the middle, and a running record that the writing is your own. Use AI (if you choose) to help you — never to replace you.
Free early beta, Windows first — register above and we'll email your download link the moment the build is posted.
…more about the betashow less
Early adopters earn a lifetime free license, and if you get really engaged, maybe even a job that pays you ridiculously. We're doing Windows first purely by an accident of fate: I broke my MacBook screen, sent it out, and kept working on a Windows machine (stupid, right?). macOS & Linux soon.
Automatic, non-disruptive updates are coming — when they ship, they'll land quietly when you close the app; we'll never rudely interrupt you or nag you to update.
One thing we need to fix ASAP: the apps aren't code-signed yet, so on first launch Windows may warn you — choose More info → Run anyway.
Who should use this?
Ten reasons, tailored to you.
Your words, on the record
As you type, PasadoDocs keeps a running account of your writing — a Transcript that shows the words are your own.
…moreshow less
Need to paste something in? You can — but there's a record of it, and you can work it until it's yours. A stack of metrics grounded in physics and linguistic science builds what we call your Core; comparing new writing against it shows you where to make sure every word is genuinely your own. The engine learns as you type, so it only gets better at recognizing you.
Your Core grows with you
The more you write, the stronger your Core gets — accuracy climbs as your Core grows. If you start using PasadoDocs as a freshman, by the time you graduate high school you'll likely have a fully operational Pasado Core.
…more, with the measured numbersshow less
In held-out testing, PasadoDocs identified writers from their own Core at these rates (against a chance baseline of about 11%):
- ~12,000 words → about 65% (small sample)
- ~24,000 words → about 86%
- ~48,000 words → about 92%
Below about 12,000 words there isn't yet a usable measurement, so that's our honest floor — but the trend is clear: accuracy climbs as your Core grows. All numbers are based on preliminary science and will keep improving.
Your statistics are stored locally only — they never leave your machine. You can see your progress any time under the ⚙ gear settings, along with other things you can control.
A gentle AI-likeness check
Compare a passage against our AI cores and you'll see whether it resembles known AI writing — a similarity signal, never a claim or accusation.
…moreshow less
Just: "hey, you might want to reword this, it reads a little AI-like." Every copy/paste into the document is tracked in the Transcript and visible in the interface — if you paste something in, you'll never lose track of it.
Your own typing is never compared against an AI core — only things you paste in. (Today this recognizes natural, unaltered AI writing; cores that catch deliberately deviated or disguised AI — and automatic flagging — are coming.)
The Scribble
My favorite feature is something I call the Scribble — a multi-branch history of what you typed. Backspace over something and later wish you hadn't? It's easy to recover just that line, or word. Don't want it? Turn it off in the ⚙ settings.
One clean surface
Palette, page, and notes in one calm layout — no shiny things fighting for your attention, no rage building while you hunt for the tool you need. And if the tool isn't there? Tell me. I'll build it.
Math and logic on tap
For the science writers among us: the palette deck holds formatting, symbols, Greek letters, and logic — a keystroke away. Roll your mouse over anything and it shows you a description and the hotkey to reach it fast.
What it will & won't do
It will
- Give you a full-featured surface for drafting and shaping prose — built for writers, by a writer.
- Keep a Transcript that shows the words are yours, and check new writing against your Core once it's established.
- Let AI suggest and organize, and offer a similarity signal on passages you paste in.
It won't
- Be a page-layout or office tool — no spreadsheets, slideshows, or print-shop formatting.
- Write for you. AI is never allowed to place words in your document on its own — you are always the author.
- Compare your own typing against an AI core, or make accusations.
Simple language about your privacy
The patterns that truly identify and profile you as a writer never leave your machine.
…moreshow less
Your privacy matters enormously to us. The patterns that truly identify and profile you as a writer never leave your machine — we do not transmit them to our servers. Nothing but sha256 hashes are ever saved on our end. A hacker could grab our entire database and it would be 100% useless to them. What's a hash? I explained them to my daughter and she said, "Oh, so you store the cookie, not the recipe." It's kind of like that. Your work saves as ordinary, readable text on your local machine. Know this: WE CANNOT RESTORE A DAMAGED FILE — if something happens to it, it's lost, so safeguard your work; we don't do it for you and never will. You can always export your document — even if you lock yourself out by editing the file directly to test the system (we won't ban you; we'll just lock that one file). And if you try to game the system, we welcome it — no bounty yet, but stay tuned.
