DemoVexa

DemoVexa is a desktop app for founders, product marketers, developer-relations teams, agencies and customer-education teams. It reads a local product's code, documentation and navigation, then creates narrated product demo videos without recording the screen.

Write a brief or let the connected AI draft one. DemoVexa produces a scene-by-scene script, voiceover, animated React UI and rendered video, with edits made by asking in plain language. It exports 1080p MP4s in 16:9, 9:16 and 1:1, plus covers and publishing copy.
