CursorCam
A short click-through demo answers the question every visitor has: what does using this actually look like? It belongs on your landing page, in your README and docs, in a launch post and in onboarding emails. The hard part has always been recording it: a clean account, a steady hand, a screen recorder, then an hour of zooming in by hand.
What makes a demo easy to follow
| Habit | Why it works |
|---|---|
| One flow, start to finish | Viewers follow a story, not a feature tour. "Save a scene" beats "everything in settings" |
| The camera goes where the click is | A full 1080p window is unreadable on a phone. Zoom in on each action, then zoom out when the flow moves on |
| A cursor that glides | Real mouse movement jitters. A smooth path and a ripple on each click show exactly what happened |
| A short pause on the result | End on the thing the flow created, held long enough to read |
| Realistic, short text | Type a real-looking name, never placeholder gibberish or personal data |
| 10 to 40 seconds | Long enough for one task, short enough to autoplay in a feed |
Record one with CursorCam
CursorCam is a free, open-source Skill that turns these habits into a routine your agent follows. Ask it for a demo of your app and it:
- checks that your app is running, or starts your dev server,
- explores the pages and writes the steps: clicks, typing, picks from menus, drags,
- dry-runs the steps and fixes any that fail,
- records them in a hidden browser and renders an MP4 with auto-zoom, a smooth cursor and click ripples,
- reads stills of its own video and fixes framing problems before handing it back.
A good request names the flow and where the video will be posted:
Make a 20 second demo of http://localhost:3000 for X: sign up and create a project. End on the new project.The steps are saved, so when your app changes you record again with one command. A new size for YouTube, LinkedIn, Discord or a square post renders in seconds from the same recording.
Add sound afterwards
CursorCam's video is silent, which is right for docs and READMEs. For a landing page or a social post, lay a quiet music bed under it and add soft clicks on the click times. The sample on the Skill page was made this way for our house smart-home app, Solenne.
