This project is a multi-agent interactive classroom platform developed by a Tsinghua team, which can generate immersive courses from any topic or document with one click. AI teachers and intelligent classmates conduct real-time teaching, discussion, and interaction. It features built-in whiteboard drawing and text-to-speech, and courses can be exported as PPTs or interactive web pages, supporting 3D visualization, simulation experiments, mini-games, mind maps, and online programming
