Gemini 2 now has a ranking system that allows users to level up though in-app achievements. Cleaning specific amounts, or completing the preset achievement based goals unlocks icons and new achievement levels for the user. Users can progress through the ranks until they have unlocked all the apps secrets and become Gemini Masters.
Gemini is smart. It easily tells copies from originals. It knows which files to keep intact. But the best thing is that it learns to select duplicates the way you do. Gemini's algorithm remembers what you delete and what you choose to keep. It's like an apprentice you are training.
