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.

Five AI readers, one verdict, and a scene-by-scene read of your screenplay
Five independent AI readers each score the draft and give a verdict, so you can tell recurring, real concerns from one reader's taste.
A synthesis shows the average score, the range, where readers converged, and the reasoning behind why the draft does not score lower or higher.
The patent-pending Layered Read analyzes acts, sequences, and individual scenes, so you can see that a scene which sags alone may be carried by its sequence.
For weak spots you get concrete options, what each gains, and what it costs, plus a chat to work through the rewrite.
