The promise
The model lives on your device. So do the documents.
Most AI apps are a thin skin over someone else's server.
No telemetry
Nothing is measured, nothing is reported.
No subscription
There is no per-token bill.
One exception, and you control it
Web search is the only feature that touches the internet.
What it does
A reading room, a study desk and a print shop.
Ten workstations around a single library.
The engine
Seventeen models. You choose the one your phone can carry.
No model ships inside the app.
Instant, runs anywhere
The app measures your device's memory and free storage.
Twenty-three languages
The interface, the assistant and the translations — in your language.
Not just the buttons.
Tap a language to read this page in it.
The craft
Built to be read for hours, not glanced at for seconds.
Cream, not white
Pure white is exhausting over a long revision session.
Liquid glass, assembled by hand
Phones have no backdrop-filter.
A real dark mode
Not grey.
Colour is never the only signal
The active tab carries a dot as well as a tint.

Said plainly
What a model on a phone can and cannot do.
It invents.
Every book it writes carries a printed notice saying so.
It takes its time.
Writing a book on a phone is minutes, not seconds.
Bigger is genuinely better.
A 0.5B model files documents poorly.
Translation retypesets.
The result is a newly laid-out document.
