Ex-Human

Ex-Human is a "Digital Human as a Service" platform that provides a single, unified API for building fully immersive, emotionally intelligent AI companions that communicate through text, voice, images, and video. Backed by a16z, the company lets developers design unique character personalities and generate multimodal responses at production scale. The Ex-Human API spans a multimodal chatbot (roleplay and realistic-chat models with long-term memory and smart replies), image generation (personalized gallery images and avatars via the persona-2 and supreme models), talking-head avatar animation (lip-sync from text or audio), image-to-video animation jobs, and text-to-speech. It is trusted by large consumer-technology companies to power AI companions, entertainment and gaming NPCs, dating experiences, AI twins, education tutors, and healthcare and therapy support at scale.

Ex-Human publishes 4 APIs on the APIs.io network, including animations API, chatbot API, Image Generation API, and 1 more. Tagged areas include Company, Artificial Intelligence, Conversational AI, AI Companions, and Generative AI.

Ex-Human’s developer surface includes authentication, documentation, API reference, getting-started guide, changelog, pricing, signup flow, and 18 more developer resources.
