Atim

AI Agent through IM — Talk to Claude Code (and other AI coding agents) through Telegram or Feishu.

Telegram / Feishu  ↔  tmux  ↔  Claude Code / Copilot / Codex / Mimo

Atim bridges an IM chat directly to a tmux window running an AI coding agent. Type in Feishu or Telegram — it reaches the agent's terminal. The agent responds — you see it in the same chat.

Features

• Multi-IM: Feishu/Lark + Telegram
• Multi-agent: Claude Code, Copilot CLI, Codex CLI, Mimo — auto-detected
• Topic isolation: Each Telegram topic / Feishu topic group maps to a dedicated tmux window
• Session recovery: Auto-recovers after restart, resume from where you left off
• Voice messages: Whisper transcription via OpenAI API
• Lightweight: Rust single binary + tmux, minimal resource usage
