This drives the WeChat desktop app on your own computer, so an assistant can send a message to a contact or group, send several at once, or fetch a day's chat history. It works by automating the app's interface rather than through an official connection, so WeChat must be installed and signed in on the same machine. Worth knowing that automating a personal account carries some account risk, and history is best fetched a day at a time.
