Real-time interactive avatars and video agents for practice, learning, and fan engagement
Give an AI a face, a voice, and a personality that sees, hears, and responds in real time, turning scripted exchanges into genuine live conversation.
Rehearse the conversations that matter most in your field using avatars trained on real-world scenarios, with every session scored against explicit evaluation criteria.
Learn in-demand skills through cinematic lessons paired with spoken, real-time feedback from AI tutors.
Combine the AI engine with a scalable intelligence framework to run agentic workflows that fit your operational needs.
Photorealistic digital humans that respond in under 300 milliseconds
Avatars respond in under 300 milliseconds, so conversations feel immediate rather than delayed, and they keep listening, reacting and breathing while waiting for the user.
Rendering happens on-device instead of streaming video from the cloud, which cuts bandwidth to 10–15 KB/s and compute cost to roughly one hundredth of typical cloud video avatars.
Web, iOS and Android SDKs plus simple APIs let developers integrate digital humans into existing apps and agent stacks without a heavy backend.
Appearance, behaviour and voice can be tailored to your brand or AI experience, with natural, controllable motion rather than stiff scripted animation.
