Protoface
Real-time avatar API for AI agents and apps from $0.01 per minute
Protoface is an API for adding real-time talking avatar video to voice agents, apps, websites, and LiveKit workflows. Developers can connect it to their existing speech-to-text, LLM, and text-to-speech stack, then stream an avatar that speaks and responds in real time. Teams can also create custom AI faces in seconds, making it easier to build branded support agents, sales assistants, tutors, onboarding guides, and other face-to-face AI experiences. Protoface is built for production use, with pricing starting as low as $0.01 per minute at scale.
