About Demokaze
Erik Nielsen
Founder, Demokaze
Stockholm, Sweden
I'm Erik Nielsen, a product designer and builder based in Stockholm, Sweden. I've spent 15+ years designing and shipping digital products, from leading design at Telenor and Simployer to running e-commerce and digital marketing at Teknikmagasinet.
For 20 years, demo videos meant the same thing: record yourself, trim the mistakes, re-record when your product changes. I saw that AI had finally made it possible to replace that entire workflow. Not just speed it up — replace it completely. Paste a URL, get a finished demo video. That insight became Demokaze.
Nobody else does AI-generated demo videos. Competitors like Arcade, Storylane, and Loom all still require manual recording. Demokaze is the first tool where the AI writes the script, records in a real browser, and delivers a polished MP4 — without you touching anything.
Why Demokaze exists
Demo videos are the highest-leverage content a product can have. They convert landing page visitors, shorten sales cycles, and make launches more impactful. But the way they're made hasn't changed in two decades — you record yourself, edit, and re-record when anything changes.
Demokaze is the first generation of demo videos that write themselves. AI analyzes your live page, scripts a natural walkthrough with cinematic zoom and smooth cursor motion, and a real browser records it as an MP4. The result looks like a professional video editor made it — in about 90 seconds.
Under the hood
- AI analysis: Claude vision reads your page like a first-time visitor and scripts the walkthrough
- Browser recording: A real Chromium session with custom easing, cursor animation, and consent handling
- Output: H.264 MP4, 720p, optimized for web playback everywhere
- Stack: Next.js, TypeScript, Railway, PostgreSQL, Upstash Redis
