Point it at a folder, or your card. It pairs every shot's JPEG and RAW, hangs it big, and you sort with an arrow or a swipe. Nothing moves and nothing is uploaded. Only the finished frames get exported, later, when you say so.
Copy the card to a drive, verified. Reads are safe; the card is your only copy.
→On-device sharpness scan gathers the likely-soft frames into a Blur Review pile.
→Swipe keep, reject, to-edit, maybe. Both files of a pair follow the decision.

Sift scores every shot for sharpness with plain mathematics. No AI service, no account, no cost, and nothing ever leaves your machine. It gathers the likely-soft frames into a Blur Review pile so you clear the obvious misses in seconds.
