An open-source Windows desktop companion that wanders around, takes custom characters, chats, and can launch applications.

Landing page captured for the 2026-09-28 issue.

For: Windows users who want a customizable desktop companion
Worth noticing: Shell actions require confirmation; the page says dangerous commands are blocked and confirmations time out after 15 seconds.

Field notes

The feature list separates character customization, desktop behavior, assistant functions, and audio response. It names both PSD import and model3.json support, and says cursor tracking includes a dead zone and smoothing. The page lists a QQ group for help and custom-character requests; its model-download library is still described as forthcoming.
