Cyrene-Agent

Active·★ 734·MIT·Updated 2026-10-21

Cyrene-Agent is a Windows Live2D AI desktop companion centered around the character Cyrene from Honkai: Star Rail. It integrates character-based chat, personalized memory, voice interaction, and tool calling within a single desktop agent, supporting both daily chat and auxiliary work modes.

Cyrene-Agent sits in the Workflow Automation category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Live2D character always on desktop, supporting expressions, actions, moods, bubble interactions, and smart stickers.. A representative use case is Daily chat and emotional companionship as a virtual desktop pet, engaging in character-based conversations.. The listed license is MIT. GitHub stars are currently 734. Relevant tags include AI Desktop Companion, Live2D Agent.

This write-up is based on the project's README and public repository data. We have not hand-tested the tool.
