I Built a Desktop AI Companion That Walks Across Your Screen (Tauri + Rust)

Posted on Jun 12

I wanted an AI assistant that felt warm and present, not like another chat window buried in a browser tab. So I built Lil Buddy — a Tauri desktop app where AI companions walk around on your screen.

Tech stack: Tauri v2, React, Rust. Supports Claude and OpenCode as AI providers. Everything runs locally — no cloud dependency for the app itself.

8 hand-drawn companion characters with full sprite animations
Expert/persona switching for different workflows
Telegram gateway for remote access
Custom themes, system tray, workspace-aware helpers

MIT Licensed (Go crazy)

This is Developer Preview — expect bugs, rapid changes, and incomplete docs. But I'd love feedback from the DEV crowd :)
