Conversational AI has empowered the Chatbot application in recent years, making the Conversational User Interface (CUI) increasingly valuable. WhatsApp & WeChat are two of the largest world IM platforms.

What if we could turn our personal accounts into a chatbot? It will be precious for many use cases if we can turn our account into a chatbot as a practical and convenient CUI application to serve users.

However, WhatsApp/WeChat does not have an official API published to achieve that, which in turn led the open-source community to develop a Robotic Process Automation (RPA) SDK Wechaty (Apache-2.0 License, 20k+ GitHub stars, 30k+ dependents), to help developers to build a WhatsApp/WeChat chatbot in 6 lines of TypeScript/Python.
