Project AIRI is a free, open-source, self-hosted AI companion and virtual avatar platform for Windows. It provides real-time voice chat, Live2D and VRM character rendering, and autonomous gameplay capabilities for titles like Minecraft and Factorio using local or cloud language models.

Overview of Project AIRI

During my testing on Windows 11, Project AIRI ran smoothly as a standalone desktop application, utilizing native NVIDIA CUDA acceleration to keep local model processing fast without bogging down system memory. Installing via Winget or Scoop was straightforward and left no unwanted background telemetry or bloated dependencies behind. The interface makes it simple to wire up custom local backends, voice synthesis engines, and interactive avatar stages directly on your PC.
