AO Mobile is the companion app for Agent Orchestrator, the desktop workspace for agent-driven development. Your agents keep working while you step away from your desk. AO Mobile keeps you in the loop — see what every worker is doing, answer the ones that are blocked, and keep work moving from your phone. REQUIRES THE AO DESKTOP APP AO Mobile is a thin client. It connects directly to Agent Orchestrator running on your own computer, over your local network or your Tailscale network. There is no cloud service and no account to create. Your code, conversations, and repositories never leave your machine. WHAT YOU CAN DO • Live Kanban — every worker session on one board, grouped by what needs your attention: working, needs you, in review, ready to merge. • Get notified when an agent stops — a push notification arrives the moment a session needs your input, and tapping it opens that exact conversation. • Chat with any agent — full conversation history, streaming responses, approvals, model and provider switching, file attachments, and voice input for when typing is impractical. • Follow pull requests — open and draft PRs with their checks, CI status, and review state. • Talk to the orchestrator — your project-level planning agent, for thinking through direction and delegating new work. • Drop into the terminal — attach to a session's live terminal when you need the raw view. • Preview running work — open a worker's browser preview to see what it built. BUILT FOR TRUST The desktop's connection to your phone is opt-in and off by default. When you enable it, AO opens a separate local listener protected by a rotating password, and pairing happens by scanning a QR code shown on your desktop. Turning it off closes the connection immediately. GETTING STARTED 1. Install Agent Orchestrator on your Mac, Windows, or Linux machine. 2. Turn on Connect Mobile in the desktop app. 3. Scan the pairing QR code with this app. Agent Orchestrator is open source. Learn more at aoagents.dev.
