About:
Gemini is a macOS utility designed to scan storage drives for duplicate and similar files. It uses intelligent algorithms to identify copies, allowing users to reclaim disk space without manually hunting for redundant data. The tool offers a streamlined interface for reviewing scan results and safely moving files to Trash.
Key Features:
  • AI-powered detection of duplicate and similar images
  • Integration with Photos library and external drives
  • Smart Select rules to automatically choose files to keep
  • Real-time duplicate monitoring for new files
Use Cases:
  • Freeing up gigabytes of space on a full Mac hard drive
  • Organizing messy Downloads or Pictures folders
  • Deduplicating photo libraries across multiple backups
Alternatives:
  • dupeGuru – Open-source alternative that offers standard duplicate file scanning but lacks the advanced 'similar file' AI features of Gemini.
  • CleanMyMac X – Broader system maintenance suite that includes a duplicate finder module, whereas Gemini focuses exclusively on file deduplication.
