ShotStamp
Auto-tag every screenshot with metadata.
Screenshots pile up as anonymous image files with nothing useful written inside them. ShotStamp is a quiet macOS background agent that notices when you take a new screenshot and stamps helpful metadata into it — keywords, a software tag, and (if you allow it) location — so your shots are searchable later. It merges into whatever metadata the image already has and never overwrites it.
What it does
- Watches for screenshots — detects new captures using filename and Spotlight hints, wherever macOS saves them.
- Writes EXIF/ImageIO metadata — keywords and a software tag, with optional GPS coordinates.
- Non-destructive — existing keywords are preserved and de-duplicated, never clobbered.
- Runs quietly in the background as a small agent.
Status: Built — the detection and metadata-building core is complete and unit-tested (it even builds on Linux), with a macOS integration layer over ScreenCaptureKit and ImageIO. It is not yet packaged as a released, signed macOS app. Source lives in a private GitHub repository.
