ChatGPT for Wechat is a Chrome add-on developed by ln2e that allows users to automatically respond to Wechat messages using the power of ChatGPT. This personal assistant version of ChatGPT acts as a Wechat bot, providing quick and automated replies to messages.

Once the setup is complete, users can test the functionality by sending a message with the prefix "@gpt" to the Wechat File Transfer Assistant. If they receive a response from ChatGPT, they know that the integration is working correctly. The add-on also allows users to switch between different AI sources by clicking on the plugin icon in the top right corner.

In addition to the default AI source, ChatGPT for Wechat also supports Bing Chat and Google Bard AI sources. However, users need to apply for access to these additional sources on their own. It's worth noting that Google Bard currently supports Chinese queries as well.
