Describe the demo. Get the video.
Understudy turns a short gameplan into a branded, narrated, slow-scrolling walkthrough. No recording, no re-takes, and never any manual audio-to-video syncing.
Submit a gameplan
Drop a URL and describe what to show. Quick mode lets Claude fill in the scenes.
Audio is the clock
ElevenLabs narrates each scene and returns exact word timings. Visuals are driven to match.
Edit text, not video
Change a line of narration and the on-screen timing recomputes itself. No syncing, ever.
Render on brand
Playwright records the timed walkthrough, ffmpeg adds your branded intro, outro, and captions.
