Build realtime AI apps that can see, hear, and speak
A drag-and-drop App Flow Builder connects inference, logic, and state nodes so you can design complex realtime flows without custom glue code.
Built-in low-latency orchestration for vision-language models, speech-to-text, and text-to-speech in a single pipeline.
Combine video, screen, audio, and text from several streams and participants simultaneously for rich interactive apps.
Mix and match building blocks, or write custom nodes to interface with your own API or SDK so the AI can act on external systems.

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.
