Make a finished demo video of a piece of software: drive the app on screen (web, macOS desktop or terminal) while narrating what it does, generate an AI voiceover and optional on-camera presenter, and render a polished MP4 with Remotion — or cut a vertical 9:16 Short (YouTube Shorts, Reels, TikTok) from one. Use when the user asks to "make a demo video", "record a demo", "create a product video", "make a walkthrough", "show off this app", or asks for a "short", "reel", "TikTok" or "vertical video" of their software. macOS only.
