In the online entertainment scenario, chats, barrages, and gifts in the live streaming room are all sent as chatroom messages, or more accurately, custom messages to show special effects or process relevant businesses.
In social platform applications, users would communicate with others for stranger socializing, gaming, or Metaverse interactions. Sometimes, such communications are done through one-on-one messages, and other times multi-user chats are also used through group chat messages.

Chatbots powered by AI engines, whether in software like online customer services or hardware like smart speakers or watches, all transmit directives through IM systems. A typical design is receive messages through message subscription services, and send replies through server-side APIs.

Multiple AI services are currently built in, compatible with various LLMs. Customization is also supported through documentation. Login for further information.
