Spotless is like a maid for your Mac. It tidies everything up for you, and once it’s learned a few rules (JPG files go in the Pictures folder, for instance), it can even do it automatically. It’ll take your Mac from a mess of disordered files to the very picture of organisation.

Manually searching for file duplicates is time-consuming. Let Gemini 2 do it for you.
