Cyphir turns your iPhone into a control surface for AI coding agents running on your Mac or PC. Start sessions, send instructions, monitor activity, and stay close to your AI-assisted development work even when you are away from your desk. CONTROL YOUR AI WORKFLOW Cyphir lets you connect your phone to supported coding-agent sessions on your computer through the Cyphir bridge. From your iPhone, you can send commands, follow session activity, and keep visibility into what is happening on your machine. BUILT FOR AI CODING AGENTS Cyphir is designed for developers, builders, and power users who run tools like Claude Code, Codex, and other local AI-assisted coding workflows. Your computer runs the agent. Your phone becomes the command and review layer.
