Momentum
Persona is an open-source desktop application (Electron) that displays an animated 3D VRM character on screen and drives it in real time via lip-sync and body animation whenever a voice AI (e.g. ChatGPT or Codex) produces audio output. The app detects speech purely through system audio capture (RMS amplitude), does not run language models itself, and connects AI agents via a local MCP server that exposes animation controls. The source code is released under the MIT license; bundled character models and animations are subject to separate licensing terms.
