Run Claude Code (or Codex and any other AI agent) from your iPhone. Cortex Relay gives you two ways to work with Claude Code on a remote machine — a friendly chat UI and a full-blown SSH terminal. Pick the right tool for the moment. THE CHAT Speak or type a prompt. Claude Code runs on your server, and the response streams back as a clean conversation with tool activity, cost breakdowns, and one-tap shortcuts for common tasks like committing, reviewing branches, or checking status. Upload photos from your camera roll and Claude can see them too. THE TERMINAL A real SSH terminal session. Cortex Relay renders the full CLI experience — interactive permission prompts, slash commands, MCP integrations, vim, git, whatever you need. Seven color themes from Nord to Dracula, pinch to resize, and a shortcut bar for /compact, /clear, /model, /status, and /cost. VOICE INPUT On-device speech recognition powered by OpenAI's Whisper. Pick a model size (tiny, base, small) and language (English or multilingual). Runs entirely on your phone — no server round-trip, works offline. Apple's built-in speech engine is available by default too. SESSIONS THAT SURVIVE Every terminal session runs inside tmux. Background the app, lose WiFi, switch to a call — your session keeps running on the server. Come back and everything is exactly where you left off. No reconnect dance. NOTIFICATIONS Get a push when Claude finishes a long task or needs your approval. The chat sends these automatically. For terminal sessions, drop a one-line webhook into your project's CLAUDE.md and Claude does the rest. SECURE BY DEFAULT Generate ed25519 SSH keys directly in the app or import your existing ones. Keys live in the iOS Keychain, optionally locked behind Face ID or Touch ID. Password auth is supported too, with the same biometric protection. Your credentials never leave the device. ORGANIZED Create named servers with saved directories. Spin up Chat or Terminal connections to any project on any machine. Each connection remembers its own dictation preferences. One server, many projects, zero re-entering credentials. YOUR TERMINAL, YOUR WAY Navy, Homebrew, Nord, Dracula, Solarized Dark, One Dark, Pure Black — pick a theme, see it applied instantly. Pinch to zoom the font size. It sticks between sessions. WHAT STAYS ON YOUR PHONE - SSH keys and passwords in iOS Keychain with biometric lock - Whisper speech recognition runs on-device only - No credentials sent to our servers - Push relay handles notification delivery — nothing else

Remote terminal access for AI coding agents. Manage Claude Code, Codex, Gemini CLI, OpenCode, Qwen, and OpenClaw sessions from your phone and Apple Watch. • Sending messages to and receiving output from remote AI coding agents (Claude Code, Codex, Gemini CLI, OpenClaw)* • Cross agents aduit, review, plan, brainstorm, or discuss • Viewing live terminal output from remote development sessions • Browsing and edit remote project files, uploading files or photos from the device, downloading files from the server • Viewing repository information and file changes (git diffs) • Running and monitoring multiple agents in parallel • Receiving push notifications when agents complete tasks or need attention • Voice input for hands-free interaction • Biometric authentication with Face ID / Touch ID • Multi-server dashboard — manage agents across all your machines • Self-hostable — deploy the open-source server on your own infrastructure IM.codes is a developer tool — not an AI service. A daemon runs on your dev machine and manages terminal sessions through tmux. This app connects via WebSocket for real-time remote access, the same way an SSH client works. AI agent CLIs (Claude Code, Codex, Gemini CLI) are third-party tools that you install and authenticate independently on your own machines. The relay server is fully open source under MIT. Self-host for production use, or try the demo at app.im.codes. Source: github.com/im4codes/imcodes
