Vapi
Protoface turns Vapi-powered voice agents into realtime avatars.
Protoface + Vapi: realtime avatar voice agents
Vapi makes it fast to build conversational voice agents. Protoface turns those agents into high-fidelity realtime avatars.
With the Protoface Vapi integration, your assistant’s speech becomes expressive avatar video, turning a standard voice experience into something more visual, personal, and engaging.
Launch in under 5 minutes
The Protoface Vapi quickstart gives you a runnable starter app for connecting a Vapi assistant to a Protoface avatar. Add your Protoface, LiveKit, and Vapi keys, start the app, and your voice agent can speak through a realtime avatar.
Protoface supports stock and custom avatars, works with existing voice AI stacks, and scales from prototype to production at $0.01/min on paid plans. For deeper setup details, explore the Protoface docs.
What Protoface adds to Vapi
Use Protoface when your Vapi agent should feel more present than audio alone, from customer support and healthcare intake to financial onboarding, ecommerce product concierges, education tutors, recruiting workflows, and SaaS onboarding. Anywhere a Vapi voice agent already helps users, Protoface adds visual presence, expression, and trust.
