Verdict
You can vibe-code a 'good enough' browser recorder for demos. Screen Studio's premium feel is native craft, not a prompt.
What you can rebuild
A rough web recorder (browser screen capture API) with basic trim and export. Or a script that post-processes a raw recording with zoom keyframes if you accept ugly v1 motion.
What stays hard
Screen Studio's value is native Mac capture quality plus tasteful automatic motion design. Matching that polish in the browser is the whole product.
Starter prompt
Build a Screen Studio-inspired web tool called SoftCapture. Use the browser Screen Capture API to record the tab/window, show a simple timeline, let users set zoom focus points manually on the timeline, preview with CSS transforms, and export WebM/MP4 if feasible. Stack: Next.js, Tailwind. Honest UX copy: this is a web MVP, not a Mac app replacement.
Follow-up prompt
Add: cursor highlight, background wallpaper behind a floating window recording, keyboard shortcut to start/stop, and project save. Document browser permission limitations.
