Why Build Demos Here
Built around your recording
Drop the screen recording on the timeline, trim the dead air, split it at each feature and put a chapter marker in front of each part.
Cards that explain
Product name, three-word features, a pill label to point things out, a before → after, a traction metric and a call to action — all editable titles.
Captions included
Auto-transcribe the voice-over on your device, fix the lines and burn them in, or export an .srt for the player.
One cut per channel
16:9 for the site and YouTube, 9:16 for Shorts and Reels, square or 4:5 for LinkedIn — the same edit reflows to each.
Private
Unreleased features stay on your machine: nothing is uploaded to edit or export.
No watermark
Free, no account, nothing stamped on the video.
Enterprise-grade privacy
Video is decoded, edited, captioned and encoded on the device it is opened on. Nothing is uploaded, no account is needed, and the app loads no analytics or ad trackers — so unreleased products, customer footage and internal films stay inside your walls.
Frequently Asked Questions
How do I turn a screen recording into a product demo?
Open the maker, load the recording, trim and split it per feature, add a chapter card before each, caption the voice-over, end on the call-to-action card, and export MP4.
Can it record my screen?
Not yet — record with your computer’s own tool (QuickTime on Mac, the Snipping Tool or Xbox Game Bar on Windows) and load the file here.
Can I add captions?
Yes. Captions are transcribed in the browser and can be burned in or exported as .srt.
Is it free?
Yes, with no watermark and no sign-up.
Is it safe for confidential or unreleased material?
Yes, by design: the footage never leaves the computer it is opened on. Decoding, editing, captioning and export all run in the browser; the only downloads are the app itself and its open AI model files. Editing needs no account, so nothing is stored on a server unless someone chooses to sign in and sync a project — and a synced project holds the timeline (clip order, titles, settings, a small thumbnail), never the footage.
