WeChatBot is a small open-source Go project that connects ChatGPT to a personal WeChat account, so the AI can chat with your friends and groups on your behalf. Published on GitHub with about 954 stars, it is built on the openwechat library and was last updated in late 2023, during the first wave of ChatGPT-to-WeChat bridges. It is compact and config-driven: fill in a JSON config with your OpenAI API key, run it, and the bot comes alive inside WeChat.
The bot covers the three interactions a personal WeChat assistant needs. In group chats it replies when mentioned, so a group can ask ChatGPT questions together. In private chats it answers direct messages conversationally. And it can automatically accept incoming friend requests and greet new contacts with a reply, which made it popular for lightweight community and customer-service style use. Because it is written in Go on top of openwechat, it runs as a single lightweight process on a server or a home machine, with behavior controlled through a simple configuration file.
The project is intentionally minimal — a focused bridge rather than a framework — which makes it easy to read end to end and adapt. Setup follows the classic pattern of these bridges: clone the repository, copy the example configuration, add your OpenAI key, and start it with go run. Because it speaks to WeChat through the openwechat protocol library, it inherits that library’s login flow, after which the bot stays signed in and responsive to friends and groups.
WeChatBot is free and published as open source on GitHub. You only pay for your own OpenAI API usage.
