Jaz is the companion app for your own Jaz assistant — a remote control surface for the personal AI platform running on your machine. Check in on live agent work, read long transcripts, and respond to threads from your phone, without needing the desktop app or a terminal in front of you. WHAT YOU CAN DO • See recent threads at a glance, with status, live activity, and pending questions readable in a second. • Stream sessions in real time as your assistant works. • Read long, noisy transcripts made mobile-friendly — tool calls and reasoning collapse into useful summaries, while your decisions and the assistant's answers stay front and center. • Send messages and interactive responses to steer work in progress. • Answer plan approvals and permission requests on the go. DESIGN A calm, focused companion — not a server dashboard or a generic chat clone. Light and dark themes that track your system, readable typography, and motion that only ever communicates state. REQUIRES A JAZ BACKEND Jaz iOS is a companion client. It does nothing on its own — it connects only to your own remote Jaz backend over a secure connection. You pair the app to your instance by scanning a QR code shown by your Jaz server. Without a running Jaz backend to pair with, the app has no data to display. PRIVACY Jaz talks only to the backend you pair it with. Device credentials are stored in the iOS Keychain on your device.
