About

RelayAI Bridge

Features
Read full description

RelayAI lets you manage long-running AI agent work from your iPhone without moving your code out of your local machine. Pair the RelayAI local bridge with your Mac once, then start sessions, send messages, review progress, approve risky actions, and stay attached to work that is still running when you step away from your desk. RelayAI is built for people who already run local agent workflows and want a better remote control surface than constantly SSHing into a laptop from a phone. With RelayAI, you can: - chat with Claude Code and Codex sessions from your iPhone - start and follow long-running local agent sessions remotely - review message history and status updates while a session keeps running on your Mac - approve or deny tool actions when the agent needs confirmation - receive push notifications when a response completes or action is required - pair one or more Macs as local bridges - keep Codex and Claude Code running where your repositories already live RelayAI is built around the local bridge workflow, where Claude Code or Codex stays on your Mac and your iPhone becomes the control surface. You are not limited to passive monitoring. You can continue the conversation, review prior turns, route work to a paired bridge, and manage approvals from the phone while the real runtime keeps working against your local repo. RelayAI is designed around long-running work, not one-off prompts. It keeps your phone and paired bridge aligned around the same session so you can leave your desk without losing control of what the agent is doing.
