01
No internet permission
Not a promise—an absent permission. The app cannot open a network connection, and you can check that yourself in thirty seconds.
ON-DEVICE REWRITING
Make the change.
See the change.
Fix grammar or shift tone in the app you are already typing in. The model runs on your phone, every change is marked, and nothing is replaced until you say so.

You keep the final word
Every rewrite waits in a visible diff. Nothing changes until you say so.

THE REST OF THE KEYBOARD MATTERS
Private rewriting belongs in a keyboard worth using.
Autocorrect, text editing, clips, undo, emoji, and bilingual typing are part of the same everyday keyboard.
01 / 06
Type where you are
Stay in the message, note, form, or document you already opened.
KEEP THE CLOUD OUT OF THE CONVERSATION
Your keyboard sees enough.
It doesn't need a network.
Write, revise, and decide on your phone.
