Gemini 2 vs Peekaboo: questions
Does Peekaboo find duplicates in the Photos library?
- No. For photos inside Photos, use the Duplicates album in the Photos sidebar (macOS 13 and later), which merges them safely.
How does Peekaboo decide two files are duplicates?
- Exact duplicates have identical SHA-256 hashes. Look-alike photos are matched by Apple Vision feature prints. Both run on your Mac.
