Cisdem Duplicate Finder - 2026 Pricing, Features, Reviews & Alternatives

Cisdem Duplicate Finder is an AI-powered duplicate file and photo finder that helps Windows and Mac users identify and remove duplicate files and similar photos. In addition to computers' internal SSD and HDD drives and external storage devices, it supports scanning OneDrive and Dropbox directly online. The software uses the high-performance hash algorithm XXH3 for fast, accurate duplicate detection across all file types and formats, capable of finding duplicate files regardless of file names.

The software uses DINOv2 Small, an on-device deep learning vision model from Meta AI, to intelligently detect burst shots, resized or compressed versions, cropped, rotated, and edited versions, format variants (e.g., one photo in JPEG and the other in RAW), pictures taken with different angles or facial expressions, and more. Since the AI model runs completely on-device, users' photos won't be uploaded to any cloud or server.

Once the software finishes scanning for duplicate files and similar images, users can conveniently review scan results using 3 modes and tools like sorting and searching. The Smart Selection tool can help users automatically select unwanted duplicates and similar photo versions using various rules, such as Select by Filename, Select by Folder Priority, Select Newest, Select Smallest, and Select Lower-Resolution.

Cisdem Duplicate Finder provides three methods for removing selected files: Move to Recycle Bin or Trash (the default method), Move to Folder, and Remove Permanently. When handling OneDrive and Dropbox, it will move selected files to the cloud service's built-in recycle bin. This way, users are able to easily restore files when needed. In addition, there's a deletion confirmation to prevent accidental deletions.
