Could you build this?

Partial The share-link and S3 upload flow and the UI are buildable, but the macOS capture pipeline with ScreenCaptureKit, smooth cursor rendering, and auto-zoom needs native media expertise that vibe coding alone may not deliver reliably.

What it would actually take: Build in Swift using ScreenCaptureKit and AVFoundation for capture and compositing, with cursor-tracking data reprocessed for smoothing and zoom. Captions can use a local Whisper-style model, and sharing goes to S3/R2 through presigned URLs. The hard parts are real-time capture performance, permissions handling, and post-processing timelines, which require experienced macOS media engineers.
