Show HN：ShutterSnap – 利用 AI 尋找並清理 Photos.app 中的相似照片

Reclaim Your Storage.Keep Your Best Photos.

ShutterSlim uses AI to find similar photos in your Photos.app library and helps you decide which to keep—you review every suggestion before anything is deleted.

Your photo library is full of similar shots you don't need.

Burst mode shots. Multiple takes of the same scene. Slight variations you'll never look at twice. Over time, these pile up—wasting gigabytes of storage and making it harder to find the photos that actually matter.

Smart detection of similar photos that actually works.

AI-Powered Analysis

Uses Apple's Vision framework to create neural network fingerprints—not just filename or timestamp matching.

Quality Scoring

Suggests the sharpest photo with the best composition, face quality, and resolution—but you make the final call.

You're In Control

Nothing is deleted without your approval. Review every group, then confirm before anything is removed.

Lightning Fast Rescans

Smart caching means the first scan takes minutes, but future scans take seconds.

Flexible Scanning

Scan your entire library, specific albums, or folders. Clean up vacation photos without touching everything else.

Native macOS Experience

Built with SwiftUI. Reads directly from your Photos.app library—works with photos stored locally on your Mac.

Three steps to a cleaner photo library.

Select & Scan

Choose an album, folder, or your entire Photos.app library. ShutterSlim analyzes every locally-stored photo using AI to find visually similar images and groups them together.

Review & Decide

See groups of similar photos side-by-side with quality scores. The AI pre-selects the best photo in each group, but you have full control to override any decision.

Confirm & Clean

Review your trash before deletion. See exactly how much space you'll free. Deleted photos go to Photos.app's Recently Deleted for 30 days—just in case.

Fullscreen comparison for pixel-perfect decisions.

When you need to see every detail, enter fullscreen mode. Compare photos at full resolution with keyboard shortcuts for lightning-fast decisions.
