Duplicate Pin Detector
Upload images (downloaded pins or exports) and detect near-duplicates using perceptual hashing.
Upload
Works best on the same aspect ratio (e.g., 2:3 pins).
Duplicate groups
Upload images and click “Find duplicates”.
Tip
If you keep saving the same idea, Notestopin tags can help you see duplicates by intent (e.g.,
#kitchen-layout).
