Verdict
A Loom/Cap-style shareable recorder is a strong vibe project and a plausible indie product if you nail share links and speed.
What you can rebuild
Record screen + webcam bubble in browser or desktop wrapper, upload to storage, share a link with timestamped comments. Instant replay page.
What stays hard
Reliable multi-platform capture, team workspaces, and transcription quality. Cap's open-source angle also means you are competing with a free repo, so differentiate on UX/hosting.
Starter prompt
Build a Cap/Loom-like recorder called InstantTake. Record screen (and optional webcam PIP), upload the video, generate a share link with an embedded player, and allow timestamp comments. Stack: Next.js, Tailwind, Supabase storage + auth. Fast share page is the priority.
Follow-up prompt
Add: auto transcription with clickable timestamps, team workspace, and password-protected links. Offer a download button for the raw file.
