Hey Product Hunt! I built PRAI to make product demos reproducible.
• Capture your real app — target named UI elements
• Edit in musical beats — camera moves, clicks, cuts
• Define everything in JSON — preview and render locally
• Add captions, narration and music
• Use Claude Code to direct and Codex to review
PRAI’s own launch video was made with PRAI. Clone the repo and re-render the examples.
Early release:
• Tested on Windows 11
• 16:9 layouts and steady-tempo music
• Apache-2.0 code; Remotion licensing applies separately
What would you build first: a launch video, feature walkthrough, or changelog demo?
