Otto is the control surface for your AI agents. Your agent runs on your own Otto device, not on rented cloud servers. The app is how you talk to it, see what it's doing, approve what matters, and stay in control of everything running on your behalf from anywhere. CHAT WITH FULL VISIBILITY Work with your agent in a conversation built for real tasks. Follow its reasoning as it works, see every tool call before it happens, and get a push notification the moment it needs a decision from you. Your agent asks before doing anything consequential. You approve or decline, and it picks up where it left off. SEE EVERYTHING IT DOES Live activity for running and completed tasks, agent logs, file browsing, and a remote shell when you want to get hands-on. Nothing happens off-screen. ONE-TAP CONNECTIONS Passkey links your agent to the services you already use. The app handles the sign-in flow on your phone, so your agent never has to juggle tokens or config files. SPEND UNDER CONTROL Gateway shows exactly what is being spent, by agent, by model, over time. Set per-agent limits and usage caps, and switch between cloud and on-device models. RUN A FLEET Manage multiple agents across multiple Otto devices from one place. Give each one its own identity, email, and phone number, and check in on any of them at any time. SET UP BY TAPPING Hold your phone to a new Otto to pair it over the local network. Wi-Fi setup, software updates, and device settings all live in the app. PRIVATE BY DESIGN When you are away from home, the app reaches your device through Otto's encrypted relay. Messages are end-to-end encrypted, so there are no ports to forward, no VPN to configure, and nothing readable in between. Sign in with a passkey or with Apple. REQUIRES AN OTTO DEVICE Otto is the companion app for Otto hardware running Otto OS. An Otto device is required to set up and run an agent. Learn more at myotto.ai.
