And if you’re wondering what tech reviews say about Gemini 2, wonder no more: we’ve gathered some of them below.
“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.”

- 9to5mac
“If you want to clean up your Mac, but are trepidatious about digging around in your files and accidentally deleting something important, Gemini 2 has a lot to offer and makes the whole process very simple.”
“With Gemini 2 there’s little reason to fear duplicates. It has a polished, intuitive user interface and the brains to differentiate copies from originals by testing them against nearly a dozen different parameters. It’s also much faster, especially compared to digging through thousands of files and folders the old-fashioned way.”

Great at finding duplicates and similars!

I just got rid of over 30G of duplicate files, some of which have been floating around for a decade or more. I found the interface fairly easy to use (though at times got a little mixed up and had to remind myself to select the one I want to DELETE, not KEEP!) It’s great at identifying duplicates… but don’t expect it to be 100% spot on. I did have to make some manual changes after the scan, and that did take a little time, but far LESS time than making a manual comparison to all files scattered across three hard drives. I would recommend always, ALWAYS, visually inspecting all matches before deleting. One thing I wish it would do, for when it finds duplicates scattered between two folders, is remember which folder you kept them in (much like it remembers whether you prefer older or newer, higher or lower resolution (or bitrate)). It’s probably a little bit more complex an algorithm to track, so I understand why it’s not part of the patterns it can detect. Also, it would be nice if it could flag any folders that were rendered empty after a purge, but I understand that, too, is probably above and beyond.

best duplicate finder i’ve used

photography and drawing are my hobbies. i have a photo archive of over 25K pics and another with many hundreds of drawings. As you probably know, many apps like this just grab all versions of a pic that are close to each other or similar. Gemini is more fine tuned. this app detects small differences, which is great. It will notice if i change just a few lines on a drawing or alter a small part of a photo. the price doesn’t bother me - i paid for it once a couple of years ago, i keep getting the updates free, it always works well and i use it constantly. good value

False advertising: Can't de-deduplicate cloud storage

This review is only for de-duplicating files in the cloud, which is what I needed, and what Gemini 2 can't do, despite what it advertises. I didn't try de-duplicating files on my computer. I downloaded Gemini 2 because it says, ""delete duplicates in cloud storage like Google Drive and Dropbox." It can't do that. I tried, eventually wrote to support, and they replied, "there is no possibility to scan your cloud storage with Gemini 2." They suggest downloading all cloud files and then scanning them locally. First, if I had room on my computer for all my cloud files, I wouldn't have much need of a de-duplicator. Second, even if I did download everything, all Gemini 2 could do is delete the additional duplicates that I'd just created in doing so. I'd still have to manually find and delete each corresponding file in the cloud. It's not just the app store that makes the false claim -- their website also says, "Duplicates are sneaky, they don’t just live on your Mac’s hard drive. Our duplicate finder scans and locates hidden copies wherever they are... Cloud Storages (Dropbox, iCloud)..." These false statements resulted in a big waste of my time.
