DoomBox

Snap each paper from the pile. DoomBox reads it, works out what it is, and sorts it where it belongs — a bill with its due date, a form that needs a signature, a letter worth keeping for reference. One tap to confirm, and the camera is back for the next sheet.

Built for the hundred-sheet stack: sort fast as it comes in, then a periodic review re-checks the piles, catches anything misfiled, and puts what's urgent on top.

Every paper keeps its photo. Once it's in, the original can go.
