Protoface adds a realtime animated face to AI voice agents: it generates an expressive avatar that lip-syncs to the agent's audio output, including full-face motion and active-listening expressions while the user talks. Custom faces are created from an uploaded image with no training step, and avatars can be lifelike or stylized.
It is aimed at developers of existing voice-agent stacks — documented integrations include LiveKit, Pipecat, Vapi, Agora, ElevenLabs agents, and OpenAI Realtime — with sub-300ms latency cited for conversational use. Pricing is usage-based at $0.01 per minute beyond a free tier, with enterprise plans for higher concurrency.
