Soul Machines

aid: soul-machines
name: Soul Machines
description: 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.

- name: Soul Machines Digital Person Session
  description: Real-time WebSocket session API used by the Web SDK to connect a browser client to a Digital Person running
    on the Soul Machines session server. A session is authenticated with either an API key (configured in DDNA Studio) or
    a JWT issued by a token server, then drives speech, animation, camera, and content-awareness over a message-based protocol.

  description: REST/callback contract for building web services ("skills") that respond to a Digital Person's conversational
    user input — NLP-adapter skills, intent matching, and pre/post processing stages. Skills are implemented by the developer
    and registered against a persona; official Node and Python SDKs conform requests/responses to the Skill API schema.
