Add your xAI API key
The app uses your own xAI account — no shared server, no shared quota.
Create a key at console.x.ai
with Chat completions, Speech-to-Text,
and Text-to-Speech permissions, then paste it into the app's
Settings tab and save.
The key lives only on your phone. The app calls api.x.ai directly —
this site just hosts the APK file.
