Loom

Build me a screen-record-and-share tool to replace Loom on macOS. Requirements: - Two parts: a local recording CLI and a share server on my own VPS. - Recording: `rec start` / `rec stop` wrapping ffmpeg's avfoundation capture, screen plus mic, saved to ~/Recordings/YYYY-MM-DD-HHMM.mp4. No camera bubble. - On stop: transcode to web-friendly H.264, transcribe with whisper.cpp, then upload video and transcript to the server with rsync over SSH. - The server (Node + Express + better-sqlite3 behind my existing reverse proxy) serves each recording at an unguessable /v/<random-id> URL: player, title, date, and the transcript below it, searchable in-page. - `rec stop` ends by printing the share URL and copying it to my clipboard. Target: under a minute from stop to link for a 2-minute video. - The index page listing all recordings stays private (localhost or VPN only); the share pages are link-only, no listing anywhere. No accounts, no telemetry. - Out of scope: viewer analytics, comments, trimming, and team libraries. The unlisted URL is the entire permission model. - README: macOS screen-recording and mic permissions, finding the right ffmpeg device index, and the server deploy steps.
