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.

To be clear about what shapes it: PasadoDocs does not use your typing speed or keystroke rhythm to build your Core — how you write is what shapes it, not how fast you type. Your Core comes from your writing itself — the words, the phrasing, and how you shape and revise a draft — computed on your own machine.

…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%):

~20,000 words → about 84%
~48,000 words → about 92%

These are the two points we've actually measured (~20,000 and ~48,000 words); smaller Cores score lower, and accuracy climbs as your Core grows. All numbers are from held-out testing (BayesCore, chance baseline ~11%) 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.

An accidental side-effect: AI writing looks different

PasadoDocs is built for one purpose — helping a writer verify their own words are their own. To compare your writing against something, we build reference "cores"; for contrast, we generated a few from AI writing. The surprise: those AI cores came out distinct — AI writing seems to carry a uniqueness that separates it from how humans write. We never set out to build an AI detector. We stumbled onto a signal.

Please read this. The authorship science here — both matching you to your own Core and this AI-likeness signal — is very early, nascent, and developing. Any findings are preliminary and evolving fast. For now, treat every result as entertainment only: a thing to explore, never a verdict, never evidence, and never a basis for an accusation or a decision about anyone. The writing surface is real and yours to keep — it's the scoring that's still early.

…how the nudge worksshow less

Compare a pasted passage against the AI cores and you'll get a gentle nudge — "hey, you might want to reword this, it reads a little AI-like." A similarity signal, never a claim or accusation. Your own typing is never compared against an AI core — only things you paste in. Every copy/paste is tracked in the Transcript, so you never lose track of what came from where.

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 — so you can back it up anywhere you like: a cloud drive, a USB stick, a git repo. Only the hashes ever reach us, so your backups stay as private as everything else. Know this: WE CANNOT RESTORE A DAMAGED FILE — if something happens to it and you haven't backed it up, 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.
