Turn scripts into studio-quality AI avatar videos in minutes
Choose from 500+ stock presenters, use photo avatars, or train a custom Video Avatar that looks and sounds like you, then generate narrated videos straight from a script.
Localize one recording into 175+ languages and dialects with editable scripts, brand glossaries, voice switching and proofreading seats for native-language review.
An agentic workflow expands ideas into finished videos, with access to leading generative models for video and image generation on higher plans.
Add quizzes, branching and decision points, embed videos by link, and export SCORM packages so content drops straight into corporate learning systems.
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.
