Screenshots in.
Demo video out.
Drop in PNGs, mark the regions you want the camera to land on, write a short outline. DemoScreen scripts the voiceover, beats the cuts to music, and emails you a 1080p MP4 with captions — most 60-second demos land inside half an hour.

What comes out.
Demos we made from plain screenshots of invented products — a web app, a phone app, a developer tool, a square social post and a long-form explainer. Different template, format, voice and music each time. Every one is the real render, not a mock-up.
how it works
Four steps.
One pass.
The studio walks you through each step. Stop after step 3 and ship a silent reel, or sign off the full thing.

Write outline AI
Bullet points or prose. Becomes the voiceover script after a tightening pass.

Voice & music
Free voice and four music presets. Pro: every voice, custom music prompts.

Render
Around half an hour for a 30-second demo, longer for a full minute. Close the tab — we email you the MP4 and captions when it's ready.
