Kyōhansha is a web-based AI digital companion built to replace standard text wrappers. It features highly responsive, real-time Live2D animated avatars optimized for 60FPS on mobile browsers. Under the hood, a custom Lite-RAG pipeline gives the AI persistent long-term memory across sessions. Users can switch between distinct AI personas and interaction modes like "Vent" or "Advice" for a tailored, judgment-free chat experience.
