Soul Machines builds autonomously animated "Digital People" — AI-driven interactive avatars that combine a real-time facial/gesture animation engine with conversational AI so brands can deploy human-like agents for customer experience, sales, education, and health. Developers integrate Digital People through the Web SDK (a JavaScript library that renders and drives a Digital Person in the browser over a WebSocket session to the dh.soulmachines.cloud session server) and the Skills API (a REST/callback contract for building web services that supply the conversational responses a Digital Person speaks). Personas, API keys, and content are configured in DDNA Studio. Soul Machines was founded in Auckland, New Zealand and is a portfolio company of the SoftBank Vision Fund.
