Type something, get a verification code, attach it anywhere. Let anyone confirm a human wrote every word.
The idea is simple: a typewriter couldn't be faked. What you typed was what existed. We rebuilt that guarantee — for anything you write, anywhere you share it.
Open the Write page or Chrome extension. Type directly. Copy-paste and voice input are blocked — every character has to be earned.
Hit generate. You get a short verification code cryptographically tied to exactly what you typed.
Add the code to the end of your post, essay, or manuscript. Anyone can look it up to confirm a human typed every word.
Click the extension from your browser toolbar, type, get your code, done. Ten seconds. No tab switching, no copy-paste risk — it works right where you already are.
The Chrome extension is where we start. A global desktop hotkey — fn fn from anywhere on your computer — is where this ends up.
It's plain text — appended at the end of whatever you write, wherever you share it. No special formatting. No separate section. Just the last line.
