ChatGPT Feishu is an open-source bot that brings ChatGPT into Feishu (Lark), the workplace messaging platform from ByteDance. Maintained by Bestony on GitHub with roughly 1,200 stars, it lets teams chat with an OpenAI-powered assistant directly inside their Feishu group chats and direct messages.
The bot connects Feishu’s messaging APIs to OpenAI’s models: users mention the bot or message it in a Feishu conversation, and replies are generated by ChatGPT with conversation context carried across turns. Deployment follows Feishu’s bot/app model — you register an app on the Feishu open platform, configure event subscriptions, and run this service on your own server with your OpenAI API key. The repository includes setup documentation and video tutorials (including a YouTube walkthrough) that made it one of the most popular starting points for Chinese teams wanting ChatGPT inside their daily collaboration tool during the first wave of ChatGPT integrations. It supports group usage so a whole team can share one assistant.
Because it is self-hosted, the team running the bot controls the data path between Feishu and OpenAI, chooses the model and can adapt prompts or behaviour to their own workflow. The repository’s issue history and tutorials reflect a large community of Feishu users who deployed it in production groups.
The bot is free and open source under the GPL-3.0 license. Running it costs only your own hosting plus OpenAI API usage billed to your account; there is no subscription or per-seat fee for the software itself.
Teams that live in Feishu or Lark and want a shared ChatGPT assistant in their chats without switching tools, and developers looking for a proven reference for Feishu bot integrations.
