Claude-to-IM

English | 中文

Claude-to-IM is a host-agnostic bridge library that connects Claude Code SDK to IM platforms, allowing users to interact with Claude through Telegram, Discord, and Feishu (Lark).

This library handles all IM-side complexity — message routing, streaming previews, permission approval flows, Markdown rendering, chunking, retry, rate limiting — while delegating persistence, LLM calls, and permission resolution to the host application through a set of dependency injection interfaces.

Out-of-the-Box Solution

If you want a ready-to-use desktop application without writing any integration code, check out CodePilot — a desktop GUI client for Claude Code with built-in IM bridge support. CodePilot implements all the host interfaces for you and provides a complete UI for managing sessions, settings, and bridge connections.

Claude-to-IM was extracted from CodePilot as a standalone library for developers who want to embed the IM bridge capability in their own applications.
