Persona: Animated Avatar for Codex Voice Sessions
Persona is an open-source desktop app that puts an animated 3D character on your screen while Codex talks. It connects to Codex through a local MCP server so the AI can trigger animations and control the avatar's visibility in real time.
Persona is an Electron desktop app that displays a realtime animated 3D character (VRM format) synchronized to your AI assistant's voice output. It listens to the audio playback process of Codex and triggers character animations accordingly. A bundled local MCP server lets Codex directly command which animations to play and whether to show or hide the window — no audio is sent over the network.
Why a vibe-coder should care
If you use Codex for voice coding sessions, Persona gives the AI a visual presence — a character that reacts when it speaks rather than leaving you staring at a blank screen. Works on Linux, Windows, and macOS without sending your audio anywhere.
