Why Use an AI Keyboard on Android?
The interesting Android feature is not AI. It is that third-party IMEs are allowed.
One enable, many apps
Turn Mojikey on once under Languages & input. It can then type in any app that uses the system field: WhatsApp, Messages, Gmail, Telegram, Discord. You are not installing a plugin per app.
The cost of that power
Android will warn you. A keyboard can see the field. Mojikey’s answer is on-device typing plus AI only on tap — not a claim that nothing ever leaves the phone. Setup: AI keyboard for Android.
Who it is for
People who already write on a phone and get stuck on replies, tone, or first lines.
