Write with software that acts as your guardian by delivering visual cues into your creative process.
The tool documents. You decide.
A quiet writing surface with three properties: better source bookkeeping — a running record of where every word came from; AI-drift recognition — an on-demand read of whether a passage sounds like AI when your writing leans that way; and an accurate provenance transcript that survives sharing. Neutral by design. Whatever you use it for, the tool measures honestly; the judgments stay yours.
Your Transcript is yours — and it stays on your machine.
That running account of your writing — your Transcript — is stored locally only. It never leaves your machine, and it’s private to you. Whether you ever share it is your call, not ours — you’re the judge. Nothing about your writing goes anywhere unless you choose to send it.

Download for Windows (beta)
Windows 10 / 11, 64-bit. The installer is unsigned during beta; SmartScreen may flag it — click More info → Run anyway.
Or install from PowerShell
$m = Invoke-RestMethod https://pasadodocs.com/updates/latest.json
$dl = Join-Path $env:TEMP "PasadoDocs-Setup.exe"
Invoke-WebRequest $m.platforms.'windows-x86_64'.url -OutFile $dl
Unblock-File -Path $dl
Start-Process -FilePath $dl
Fetches the latest version from our update manifest, downloads it, strips the Mark-of-the-Web (removes the “downloaded from the internet” warning), launches the installer. SmartScreen’s bigger dialog may still fire for unsigned installers — that requires a click-through until code signing lands.
Download for macOS (beta, unsigned)
Apple Silicon (M1–M4) full end-to-end. Intel launches but the analysis engine crashes on spawn — Intel universal coming in a follow-up.
Get the tarball (~280 MB)Or install from Terminal
curl -LO https://pasadodocs.com/updates/beta/mac/PasadoDocs-universal-unsigned.app.tar.gz
tar -xzf PasadoDocs-universal-unsigned.app.tar.gz
xattr -d com.apple.quarantine PasadoDocs.app
mv PasadoDocs.app /Applications/
open /Applications/PasadoDocs.app
Downloads the tarball, extracts it, clears the quarantine flag (Gatekeeper
bypass for unsigned builds — goes away when signing lands), moves the
app into /Applications, launches it.
A new version of PasadoDocs ships nearly every day — but don’t worry, you never have to come back here again. PasadoDocs quietly updates itself, either when you close the app or if you leave it alone long enough. Hopefully it works properly and doesn’t jack up your work — but thankfully we’ve got some backup machinery in the pipe that’ll make sure you never lose anything (except maybe your sanity, dancing around here helping me stomp all the bugs).
Bookkeeping, recognition, provenance
Three things this tool does honestly, without judging you for how you use them:
Better source bookkeeping. Every paste, every copy, every keystroke — tracked into a local, private Transcript so you (and, if you choose to share, whoever you hand it to) can see the actual composition history of a document. No inference, no guessing. Just a record.
Better AI recognition when your writing leans that way. The tool learns the shape of how you write — your Core — and can, on demand, tell you whether a specific passage has drifted toward AI cadence. It’s a mirror, not a verdict — a nudge to look twice at what you wrote, hand held out to you, not raised against you.
An accurate provenance transcript. Kept locally, tamper-evident, cryptographically anchored. The Transcript is the receipt of how the document came into existence: what you typed, what you pasted, what got scored, what you decided about each finding. It travels with the document if you share it — and only if.
And one hard property: no external editing without a visible flag. A PasadoDocs document is text under the hood — easy to edit outside the app. The second anything else touches it, the whole editor turns red (at least 70% opacity, not dimmable), and the Transcript records the tamper. The tool won’t quietly let something else put words in your mouth.
The tool documents. You decide.
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 here — they land quietly when you close the app or when you leave it idle; 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.
This site, measured by its own instrument
We marked this whole site with our own tool
Every piece of prose here is wrapped in the same provenance bands PasadoDocs paints in the app, then tallied by a script — not eyeballed. Across all content pages: 77.2% the Inventor’s own words · 3% AI-assisted · 19.8% AI-generated (public-domain quotes & academic citations excluded). This landing page, honestly, is almost all AI-generated marketing copy — the Inventor’s own words live in the essays.
- in-band — the Inventor’s own words
- elevated — AI-assisted from his notes
- off-band — AI-generated
- reference — neither ours; excluded from the %
In the spirit of PasadoDocs, as the weeks pass, I will overhaul all of the AI-flagged text and make it my own. Come back next week, and watch as my Transcript adjusts to reflect my changes. — The Inventor

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 about how accuracy growsshow less
In held-out testing, PasadoDocs identifies writers from their own Core far better than chance — and it gets stronger the more you've written.
Accuracy climbs as your Core grows: a small Core is a rough guide, a well-fed one is much surer. The science is early, and we keep improving it.
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.
Full feature list
Those two are a taste. The real surface is a lot more — a revision history that fossilises every abandoned branch, a signed sharing model where the recipient’s role is enforced by the document itself, an honest-numbers status bar, a tamper-evident Transcript, and more. The full list, in the writer’s own frame, is one click away.
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.
- Be an information-governance or surveillance tool. You don't police anyone else with PasadoDocs — you use it on your own writing, to make yourself a better, more consistent writer.
A licence you can actually read. PasadoDocs ships with a plain-language licence — no legalese wall, just a handful of honest points you can read in a couple of minutes. It says in plain words what these promises mean: this is a tool for your own writing, not a way to police anyone else.
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 mass-export all your work — and if you edit the file directly to test the system, we won't ban you; the system simply detects the tampering and flags it in your Transcript. And if you try to game the system, we welcome it — no bounty yet, but stay tuned.
