Cim is a distributed instant messaging system and server-side backend designed to manage real-time communication across a cluster of servers. It provides a scalable infrastructure for routing private and group messages while tracking user connection states and session locations across distributed nodes.
The project features an interception layer for AI messaging middleware, which allows artificial intelligence agents to intercept incoming communication and generate automated responses. It also includes a real-time push infrastructure to deliver notifications and messages from the server to end-user clients.
The system covers identity management through user account registration and prefix-based discovery. Additional capabilities include group message broadcasting, keyword-based chat history search, and a queue-based scheduling system for delivering messages after a predefined delay.
