ChatGPT for WeChat

ChatGPT for WeChat is a Chrome extension landing page and source code repository for an AI chatbot that automatically responds to WeChat private messages and group @mentions using ChatGPT. It is distributed through aow.me and the landing page is bootstrapped with Vite, with the current release at version v2.1.0.

What is ChatGPT for WeChat?

ChatGPT for WeChat is a Chrome browser extension that monitors the WeChat Web (网页版) interface and uses ChatGPT to automatically reply to private messages and group chats where you are @mentioned. The extension takes incoming message text as input, sends it to one of two supported AI sources — ChatGPT or an OpenAI API key — and outputs a generated reply directly into the conversation. The project also provides a personal-assistant edition built on WeChat's File Transfer Helper (文件传输助手), which lets you chat with ChatGPT from the file-transfer window.

Key Features

• Group and private chat support — Handles both WeChat group chats and one-on-one private conversations, responding only when your account is @mentioned in a group.
• Per-user rate limiting — Enforces a configurable question frequency limit for each individual user, preventing any one person from flooding the queue.
• Two AI backends — Choose between ChatGPT (which supports multi-turn context, recommended with a ChatGPT Plus subscription) or bring your own OpenAI API key.
• Concurrent request queue — Multiple users across multiple groups can ask questions simultaneously; messages enter a queue and are answered in order without blocking.
• Personal assistant edition — A separate download based on WeChat's File Transfer Helper (文件传输助手) provides a private ChatGPT channel without involving other contacts.
• Vite-powered landing page — The repository is built with Vite, offering standard npm scripts (npm install, npm run dev, npm run build) for local development and production builds.

Who is it for?

• WeChat power users who want automated ChatGPT replies in personal chats and groups without switching apps or keeping a laptop online.
• Community and group admins who need to respond to @mentions in busy group chats, using the built-in queue to handle multiple questions fairly and rate-limit chatty users.
• Developers who want a working Chrome extension example that integrates ChatGPT with a third-party web service; the repository includes full source code and Vite build configuration.

What can you do with it?

• Auto-respond to customer questions in WeChat groups: every @mention triggers a ChatGPT answer in the order it arrived, with per-user frequency constraints to prevent abuse.
• Use as a private assistant: install the File Transfer Helper edition and send messages to yourself to get ChatGPT responses without involving any other contacts.
• Switch AI providers freely: use the hosted ChatGPT mode when you have a Plus account, or switch to an OpenAI API key for more granular control and billing.

How does it work?

The extension runs in Chrome and requires the WeChat Web (网页版) interface rather than the desktop app. After installation, open WeChat Web in your browser; the extension listens for incoming private messages and group @mentions, forwards them to the selected AI backend, and posts the returned text back into the chat window. The official website provides step-by-step video tutorials on Douyin and YouTube.
