Cisdem Duplicate Finder
Cisdem Duplicate Finder locates duplicate files and visually similar photos on macOS and Windows.
What Cisdem Duplicate Finder is
Cisdem Duplicate Finder locates duplicate files and visually similar photos on macOS and Windows. File matching is based on content rather than filenames and covers images, documents, songs, videos, archives, and duplicate folders. Similar-photo detection can identify burst shots, edited or resized images, and pictures taken from different angles or in different lighting. The maker says this AI processing takes place on the device without uploading files to a cloud or server. Users can preview results in three view modes, then sort, search, and filter them. Duplicate files can be sent to Recycle Bin or Trash, removed permanently, or moved to a chosen folder. Supported locations and services include external drives and SD cards, iTunes and Apple Music, Mac Photos, OneDrive, Dropbox, Google Drive, and iCloud. A trial can scan, preview, locate, and hide duplicates, but cannot delete all selected duplicates with one click. One-time licenses are listed at $39.99, paid once for one Mac or one PC; one-year subscriptions are $19.99 a year.
