Turn documents and decks into presenter-led training videos and interactive courses
Start from a PDF, PowerPoint, Word document, URL, script or existing video and let the platform plan and build scene-by-scene training video drafts.
Choose from 300+ stock presenters, create a custom avatar from a single photo of a team member, or use cartoon presenters — all speaking 120+ languages.
Edit the script like a document and the voiceover follows; swap presenters across scenes without re-recording.
Add quizzes, buttons and branching paths, then export scores to your LMS through SCORM.

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.

An agentic workflow expands ideas into finished videos, with access to leading generative models for video and image generation on higher plans.
