VoxDemo – Create demo videos with AI voiceovers

Hacker News

Hi HN! I’m launching VoxDemo, a browser-based tool to record your screen, add AI voiceovers, and fine-tune everything with a timeline editor. What it does: - Record your screen in the browser (no installs) - Add AI voiceovers (6 natural voices to start) - Use the timeline editor to cut, trim, and sync voiceover to the video - Share instantly via a link Why I built it: Creating narrated demo videos is tedious if you don’t like recording your own voice or wrangling heavyweight editors. VoxDemo aims to make clean, narrated demos fast. Current limitations: No “how it works” video yet, and since this is the MVP, I’ll be adding new features over time. Would love feedback on the workflow and what you’d want next. Feel free to comment here or use the feedback form on my site if that’s easier. Thanks!
