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. AI integrations that seamlessly prevent the AI from actively editing your words: you use AI (if you choose) to help you — not replace you.
Free early beta — 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. Register your email to get in — we'll send your download link the moment the Windows build is posted. Once it's installed, updates will 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.
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. Everything a writer wants, at your fingertips. And if the tool isn't there? Tell me. I'll build it.
Your words, on the record
The engine keeps a running account of your writing and learns as you type. 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 the Core; comparing your writing to it shows you what you need to make sure all your words are your own. And you can compare a passage against our AI cores to see if it reads AI-like — a similarity signal, never an accusation. Today the cores recognize natural, unaltered AI writing — in testing they tell it from human about 94% of the time; catching AI that's been deliberately deviated, altered, or retyped to disguise it is what our future deviated cores will add, along with automatic flagging.
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.

Why PasadoDocs exists
Ever since I was a young man, words intrigued me — by the way they spill down a page, but also by the patterns you can see in them that have nothing to do with the meaning: by their lacunarity. Theorizing that the way your words line up on a page when you write is not accidental led me to the notion that, perhaps, page lacunarity represents some sort of background signal — a subconscious shape that, maybe, we could detect and measure.
Thusly began this project, PasadoDocs — and thusly began several of the most disappointing weeks of my life, as experiment after experiment after experiment failed to show anything at all. It was random — until it wasn't. Finally, we had a signal, but it was faint.
That is when the journey began. I sort of gave up on page lacunarity — rivers, banks, deltas, diagonals — but, being stubborn and hard-headed, I dived into existing work in lexicology, as well as deriving some of my own tests that had to do with word impact, phrase shape, verb-form patterns, and some other stuff. I even reached deep down inside, back to my days as a lab assistant with a physics group. I started to treat the text as a physical construct and ran it through various modeling techniques. Some worked better than others, and the experiments are ongoing. The ones that worked the best ended up in the stack.
All numbers are based on preliminary science. We've done work building tampered cores — where we told the AI to deviate, to try to imitate Agatha Christie. We gave the AI the full stack of analyzers; it had access to the source code. Interestingly, it failed harder — the harder it tried to get everything right, the worse the prose got. It's like an untrained child trying to forge a Van Gogh. Sure, give them all the tools — it's still a child who can't paint.
The intended pattern of use is whatever you want it to be. Writers can use it and export documents to whatever format they like. Or you can share the document and, in settings, turn off the write protection and transcripts — your transcript will still collect, but it will be stored in the .scribble instead. Or you can be 100% transparent, and prove that your words are 100% yours.
At the end of the day, this is an experiment: can I use physics to build a thumbprint of how writers write, differently from how machines write? Join the experiment, become part of the community, and we can learn together. No accusations. No adverse inferences. Just you, at your keyboard, writing on a surface that protects you from yourself — that shows you where something you pasted might not be yours, tracks it for you, and helps you be a better writer, non-adversarially.
