AI KEYBOARD FOR GRAMMAR, TONE & TRANSLATION
A system-wide keyboard that fixes grammar, rewrites tone and translates without leaving the app you are already typing in.
WHY I BUILT IT
Every writing tool I tried lived somewhere else. You write the message, copy it out, paste it into another app, fix it, paste it back. Four steps for one sentence.
A keyboard extension removes all of them. The correction happens where the typing happens — in Messages, in Mail, in a DM — so the tool disappears and only the better sentence is left.
WHAT IT DOES
Fix as you type
Grammar, spelling and punctuation corrected in one tap, inside any app.
Tone rewriting
Turn the same sentence formal, friendly, direct or apologetic.
Inline translation
Write in your language, send in theirs — without switching keyboards.
