About

I’m building DemoMotion AI, an open-source agent that turns real web app workflows into narrated product demo videos. I’m interested in AI agents, developer tools, and helping builders communicate their products more clearly.

Demomotion AI - Turn your web app into a narrated product demo video

DemoMotion AI is an open-source AI agent turning real web app workflows into narrated product demo videos. Give it a URL and a goal, such as “show how to create a task” or “explain the onboarding flow.” DemoMotion plans the demo scenario, controls a browser, records the screen, generates narration and subtitles, and exports an MP4. It is built for developers, indie hackers, and small teams who wanna explain what they built without manually recording screens, writing scripts, or editing videos.
