Node.js
Protoface adds lifelike realtime avatar video to Node.js apps and AI voice experiences.
Protoface Node.js Integration for Realtime AI Avatars
Protoface gives Node.js voice agents an expressive realtime face. With the Protoface Node.js SDK, developers can add high-quality avatar video to JavaScript, TypeScript, React, and voice AI apps without rebuilding their agent stack, LiveKit room logic, or media pipeline.
What Protoface Adds to Node.js Apps
Protoface handles the avatar rendering layer so your Node.js app can stay focused on agent behavior, session orchestration, audio, and user experience. Pass in your avatar details and LiveKit room credentials, start a Protoface session from your app, and stream a talking avatar into your existing realtime experience.
The Protoface Node SDK quickstart covers the core setup, while the Protoface docs explain avatars, API behavior, usage, and production guidance.
Use Cases
Protoface is built for teams adding face-to-face AI to browser-based voice products, including AI sales reps, support agents, onboarding assistants, tutors, language-learning apps, interview practice tools, healthcare intake flows, coaching products, training simulations, creator tools, and consumer AI companions.
Start Building
Turn your voice AI agent into a face-to-face experience without managing avatar rendering infrastructure. Start with a stock avatar, add a custom avatar when you’re ready, and scale from prototype to production.
