What is Gemini?

Gemini, developed by MacPaw, is a utility application designed exclusively for macOS. Its singular, focused purpose is to find and remove duplicate files.

In an era where digital clutter accumulates rapidly from downloads, photo libraries, document versions, and music collections, Gemini scans a user's Mac, or specific folders within it, to identify files that are exact duplicates. It then presents these duplicates in a clear interface, allowing the user to review and safely delete the superfluous copies, thereby reclaiming valuable storage space.

MacPaw is a well-established Ukrainian software company known for its suite of Mac applications, most notably the popular CleanMyMac X. The company has built a reputation for creating polished, user-friendly utilities that address common macOS maintenance tasks.

Gemini uses this experience, presenting essentially a sophisticated file-comparison engine wrapped in an accessible and visually clean application. It is a standalone product, separate from the CleanMyMac suite, focusing solely on the problem of duplicate file management.


Who is Gemini best for?

Gemini is not an essential utility for every Mac user, but it solves a specific pain point that becomes increasingly relevant for certain groups. It is most valuable for users who have amassed large collections of files over years of use, who work extensively with media, or who are simply fastidious about organising their digital workspace and maximising available storage.

The application is particularly adept at handling large-scale, tedious comparison tasks that would be impractical to perform manually.

  • Photographers and videographers with extensive libraries containing multiple edits or imported copies of the same raw files.
  • Music collectors and podcast enthusiasts who may have duplicate audio files scattered across different folders or external drives.
  • Academics, researchers, and writers who work with numerous versions of documents and downloaded PDFs.
  • General users with limited SSD storage (e.g., 256GB MacBooks) who need to periodically purge duplicate downloads and documents to free up space.
  • Anyone who has migrated data between multiple computers or drives and suspects duplicate files were created in the process.

Key features

Intelligent Scan and Byte-for-Byte Comparison

Gemini does not rely solely on file names or creation dates. Its core scanning engine performs a deep analysis, comparing files at a binary level to ensure it only flags items that are genuine, exact duplicates.

This prevents the accidental grouping of files that are merely similar, such as different edits of the same photo or successive drafts of a document, unless they are truly identical in every byte.

The 'Smart Cleanup' Selection Assistant

After a scan, Gemini presents duplicate groups. The Smart Cleanup feature automatically selects which copy to keep, typically the one with the most recent 'Modified' date or located in a primary folder like 'Documents', and marks the others for deletion.

This significantly speeds up the review process, though users can manually override any of these suggestions with a single click.

Folder and Drive Pairing for External Drives

This feature is crucial for users with external storage. It allows you to select two specific folders or drives (for example, your internal 'Pictures' folder and an external backup drive) and scan only for duplicates that exist between these two locations.

This is far more efficient than scanning your entire Mac when you simply want to deduplicate files between a computer and a backup.

Preview Pane for Multiple File Types

Before committing to deletion, Gemini allows you to preview the contents of most common file types directly within its interface. This includes images, videos, audio files (with playback), PDFs, and text documents.

This visual confirmation is a critical safety step, providing final reassurance that you are not deleting the only copy of an important file.

Flexible Scan Selection and 'Similar Photos' Mode

You have full control over what Gemini scans. You can drag and drop any folder onto the application, use predefined quick-selection buttons for common locations like 'Downloads' or 'Music', or perform a full system scan.

A dedicated 'Similar Images' mode uses algorithmic analysis to find photos that are visually near-identical (e.g., the same shot taken in a burst), which is a common source of wasted space, though this requires more careful manual review than the exact-duplicate scan.


Gemini pricing

Gemini is sold via a one-time purchase licence, a model that is becoming less common in favour of subscriptions. According to MacPaw's official pricing pages, the standard licence for Gemini 2 is priced at £29.95 for use on one Mac.

MacPaw occasionally offers it in bundles or at a discount during promotional periods. There is no free trial, but the company offers a 30-day money-back guarantee, which allows for risk-free evaluation.

Whether this represents good value depends entirely on the user's need. For someone struggling with a chronically full 256GB MacBook Air who needs to reclaim 20-30GB of space from years of clutter, the one-time fee is likely justifiable and cheaper than upgrading iCloud storage indefinitely.

For a professional photographer using it to clean up terabytes of archive storage, the price is negligible for the time saved. However, for a casual user with ample storage and modest file collections, the cost may seem high for a single-function tool, especially when compared to the duplicate-finding modules included in broader cleaning suites like CleanMyMac X, which uses a subscription model.

The one-time fee of £29.95 is justifiable for users with chronic storage issues, but may feel steep for casual users with ample space.


What we like

  • Thorough byte-for-byte comparison is exceptionally reliable, eliminating the fear of deleting a file that is merely similar rather than identical.
  • Intuitive, visually clean interface makes the potentially overwhelming task of reviewing thousands of duplicates manageable.
  • Intelligent automation features like folder pairing and Smart Cleanup respect the user's time while retaining full manual control.
  • Built-in preview for a wide array of file types adds a vital layer of safety before deletion.
  • One-time licence fee is a welcome alternative to yet another software subscription.

What could be better

  • No free trial or limited-feature free version makes it difficult to evaluate effectiveness on your own file system before purchasing.
  • 'Similar Images' feature can be slow on very large libraries and sometimes requires careful manual review to avoid deleting wanted variations.
  • Mac-only application means users in cross-platform environments cannot deduplicate files shared with Windows PCs.
  • One-time cost may feel steep for occasional users compared to manual methods or free, albeit less polished, alternatives.

Gemini verdict

Gemini excels at its designated task. It is a powerful, focused, and safe tool for eliminating duplicate files on a Mac. Its scanning is accurate, and its automation features strike a good balance between efficiency and user oversight.

The peace of mind provided by its deep comparison engine and reliable preview capabilities is its greatest strength, transforming a risky and tedious chore into a straightforward process.

For its target audience, users with substantial, cluttered storage or professionals managing large media libraries, it is a worthwhile investment that can reclaim significant disk space and improve digital organisation. However, it is not a must-have for every Mac owner.

Casual users with small, well-organised file collections and plentiful storage are unlikely to extract enough value to justify the cost. In those cases, manual cleanup or the duplicate-finder tools within broader system utility suites may suffice.

If you are constantly battling 'Disk Full' warnings or managing a disorganised media library, Gemini is a leading solution that does one job very well.

The final assessment is clear: if you are constantly battling 'Disk Full' warnings on your Mac, if your photo or music library is a disorganised mess of copies, or if you simply value a pristine file system, Gemini is a leading solution that does one job and does it very well. For the average user with minimal storage concerns, it is a specialised tool that may be more powerful than their situation requires.
