ShutterSlim

ShutterSlim uses on-device machine learning to find duplicate and similar photos in your Mac’s Photos library—including visual similarity and face detection—helping you recover valuable disk space. Intelligent AI Detection Unlike basic duplicate finders that only match identical files, ShutterSlim analyzes the visual content of your images. It detects near-duplicates, burst sequences, similar shots, and repeated faces that quietly waste storage space. Reclaim Your Disk Space See exactly how much space you’ll save before you delete anything. ShutterSlim shows estimated savings as you review, so you understand the impact of cleaning up your library. Smart Quality Scoring ShutterSlim evaluates sharpness, exposure, composition, and facial clarity to suggest the best photo in each group. You review the suggestions and make the final decision. Safe and Reversible Photos you remove are sent to Photos.app’s Recently Deleted folder—never permanently erased without your consent. You can restore anything within 30 days. Works with Photos.app ShutterSlim integrates directly with your existing Photos library. Browse albums, scan specific folders, and clean up your collection without importing or exporting. Privacy by Design All AI processing—including face detection—happens entirely on your Mac. Your photos are never uploaded, shared, or analyzed elsewhere.
