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.

The AI lab making video that actually teaches
Point Symvol at a document, PDF or webpage and it produces a finished educational video in minutes, without a studio workflow.
Every video is generated in your institution's visual identity rather than a generic template look.
Content can be made available in more than 30 languages, so one source asset serves multilingual learner groups.
Symvol aims for visual explanations that help learners understand concepts — drawing on how people actually learn rather than just narrating slides.
