Persona Engine is a Windows desktop application that drives a Live2D avatar with an AI pipeline: microphone speech recognition, an LLM guided by a personality file, real-time TTS with optional voice cloning, and synchronized lip-sync and expressions. It includes a transparent overlay and Spout output for piping the character into OBS for streaming.

Use cases

• run an AI VTuber that listens and responds live on stream
• create an interactive AI waifu companion with a Live2D avatar
• build a virtual assistant with a talking animated character
• stream a voice-driven Live2D character into OBS
• voice-clone TTS for a virtual persona
• make a Live2D character lip-sync to AI-generated speech

When to choose

• you want a ready-to-run AI VTuber stack on Windows with an NVIDIA GPU
• you need Live2D lip-sync, LLM conversation, and TTS integrated out of the box
• you want to pipe an animated avatar into OBS via Spout

When to avoid

• you need Linux or macOS support
• you have no NVIDIA CUDA-capable GPU
• you need a library or SDK to embed in your own application rather than a standalone app
• you require a permissively licensed dependency since the repo has no license file
