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.

One-stop AI video creation, from idea to finished film
Start from a plain-language idea and let the Creator Agent draft content, plan scenes, and generate a video for you.
Organize characters, shots, and scenes freely on an unlimited board, with batch prompt upload to scale storyboard production.
Built for episodic content, so you can maintain characters, style, and continuity across multiple episodes and comic-style series.
Combine scriptwriting, image generation, and video generation in one place instead of stitching together separate tools.
