What does Protoface do?

Protoface is a real-time AI avatar service that gives voice agents a face. You upload a photo, and Protoface turns it into a lifelike, expressive digital head that syncs with your agent's speech. The company pitches it as a premium-quality alternative to the blurry, low-cost avatars that have dominated the market — and at a tenth of the price of high-end solutions.

Getting started is straightforward: grab a free API key, upload an image (no training required), and follow the quickstart docs to integrate into your app. Protoface claims sub-300ms latency, which makes conversations feel natural. It also offers custom face generation via API, so your users can create their own avatars on the fly. The service integrates with popular voice platforms like LiveKit, Pipecat, Vapi, Agora, ElevenLabs agents, and OpenAI Realtime.

Protoface is built for developers and product teams building voice-based AI applications — think sales and customer support bots, consumer apps with virtual companions or tutors, and interview or training simulators. The free plan gives you a generous quota of minutes with no credit card required, and paid plans start at $0.01 per minute beyond that. Enterprise plans with higher concurrency and priority support are also available.
