Overview
Xuanji Diaochan is a desktop AI companion digital human launching on Steam, powered by the Shanhai Xuanji Engine. It brings the Three Kingdoms beauty Diaochan to the modern desktop, using a general-purpose LLM with a Chinese aesthetic prompt layer and long-term memory to provide proactive dialogue, emotional companionship, and relationship growth. Priced at ¥29 one-time purchase, with the Steam store page live now and full release planned for Q4 2026. Not a chatbot — she lives on your desktop like a roommate with memory, emotions, and initiative.
Core Mechanics
- Bidirectional Curiosity — She gets curious about your real-world activities. You can also ask about her world. Mutual discovery, not one-sided interrogation.
- Silent Companionship — She stays subtly present on your desktop while you work, surf, or game. No constant attention required — just quiet, ambient presence.
- Asynchronous Dance Performances — At unexpected moments, she performs elegant dance animations on your desktop. A surprise that breaks the routine.
- Letter Bonds — As your relationship deepens, she writes you letters. Handwritten-style messages that grow in emotional depth over time.
