Kyōhansha is a web-based AI companion that goes beyond typical chatbot wrappers by pairing conversational AI with real-time Live2D animated avatars running at 60FPS on mobile browsers. A custom Lite-RAG pipeline gives the AI genuine long-term memory, so it retains context across sessions rather than starting fresh each time. Users can switch between distinct AI personas and choose interaction modes — such as "Vent" for emotional offloading or "Advice" for structured guidance — making conversations feel more intentional and less generic. Built for mobile-first use, it's aimed at people who want a more expressive, emotionally responsive AI companion rather than a plain text interface.
