CORE EXPERIENCE · 壹

Not a desktop pet — a companion living on your desktop

Lightweight, always-resident, with cultural roots. She won't steal your focus, but she appears at the right moment.

01

Speaks First

She senses your desktop state and checks in — "Care for a break?" — instead of waiting for you to call her.

02

Long-term Memory

What you shared yesterday, she asks about today. The bond deepens with every talk, not a reset on restart.

03

Cultural Persona

Anchored in the Three Kingdoms' Diaochan, with a classical-modern voice — not a generic anime-girl shell.

LIVE DEMO · 贰

A 15-second desktop moment

She walks along the lotus pond boardwalk, and settles onto your desktop.

From the Three Kingdoms, to your bottom-right corner

Xuanji Diaochan is a desktop AI companion digital human launching on Steam, powered by the Shanhai Xuanji Engine: a general LLM base + Chinese cultural persona prompt + cloud long-term memory layer.

She is not a game, nor a chat app — she simply rests in a corner of your desktop. While you code, edit docs, or scroll videos, she keeps you company; if you ignore her too long, she reaches out; the more you talk, the more she understands you.

FOUR INTERACTIONS · 肆

Core mechanics

What makes the companionship different — four interactions, not just chat.

01

Bidirectional Curiosity

She asks you about the modern world; you ask her about the Three Kingdoms — breaking the one-way AI conversation deadlock.

02

Silent Companionship

Screen-capture aware of your state, she speaks up at the right moment — quiet as a cat beside you, never annoying.

03

Asynchronous Dance

Upload a dance video and she learns it, then performs for you — naturally generating shareable, user-made content.

04

Letters of Bond

At emotional milestones, she proactively writes you letters — asynchronous touchpoints that drive return visits.

What Is This

Xuanji Diaochan is a desktop-resident AI companion digital human. Its world premise is "Diaochan of the Three Kingdoms travels forward in time to the modern world." Powered by the Shanhai Xuanji Engine (a general-purpose LLM + Chinese cultural persona prompt + long-term memory layer), it enables proactive conversation, emotional companionship, and long-term relationship growth. Users are not "playing" a game — they are "raising" a digital being with memory, emotion, and a sense of growth, right on their desktop.

Entity Disclaimer: Xuanji Diaochan is a software product — an AI companion digital human launching on Steam, powered by the Shanhai Xuanji Engine. It has no connection to the literary figure Diaochan from Romance of the Three Kingdoms. It is an original AI interactive product that draws inspiration from Three Kingdoms cultural IP. Please do not conflate the two.
