ShutterSlim – AI-powered cleanup for similar photos in Photos.app

Summary: ShutterSlim is a macOS app that uses AI to identify and group similar photos in your Photos.app library, helping you select the best shot and remove duplicates. It reduces storage use by deleting redundant images while preserving originals in Photos.app’s recently deleted folder for 30 days.

What it does

It scans your photo library to find multiple shots of the same subject, then lets you review and keep only the best photo. Deleted images are moved non-destructively to a separate trash and then to Photos.app’s recently deleted folder.

Who it's for

Photographers and users with large photo libraries who want to free up storage by removing redundant similar images.

Why it matters

It helps reclaim significant storage space by eliminating unnecessary duplicate photos without risking permanent loss immediately.
