Description

Detect duplicates, spot similars, and wipe them away. Gemini 2 finds duplicate files with laser precision. Tech reviews agree:

"Gemini, our favorite duplicate file finder for Mac, got a big update today that modernizes the interface and improves the file scanning algorithm so it can find more duplicate files even when they’re not named the same thing."
– Lifehacker

"I’ve been an active user of MacPaw’s Gemini software since its inception, and Gemini 2’s release today has made me fall in love with it all over again. In just the initial scan, Gemini 2 found more files and more places where I could intelligently clear and save space on my Mac."

Close but painful gaps

This app is close to what it could be, but falls short. For example, the “intelligent” selection fails to notice that the selections for what to delete are all in the same folder. Not only should it figure this out, when dropping multiple folders on the application at the same time it should allow prioritization on the spot. The “similar” algorithm could use some controls to be better at distinguishing consecutive pictures versus resized or otherwise adjusted pictures. It also could cue on exif data to identify originals.

didn’t help me

I have a hundred’s of duplicates. Some appeared to have the same exact file name and date. These files were not caught by Gemini. I reached out to their help desk. After some back and forth they let me know that the files were somehow slightly different. I’m not sure how different, same file name, date and duration (for the videos). They insist that they’re not the same. I can’t really argue, but I know that this program didn’t do what I thought it would.

Super easy but still detailed

This is quick and easy when it needs to be and gives the option for more in depth analysis when I want it. Great app. Free up some SPACE!!!
