One click scans the shot and proposes the boxes. Nothing turns black until you say so.
Because a black-out can't be undone once you share the picture, it never blacks out a guess on its own. It proposes coral boxes over what it found (emails, phone numbers, street addresses, Social Security-style and card/account numbers), you glance and adjust, then Black it out (Enter) blacks them out for good in one undo step. A wrong flag is one click to dismiss; anything it leaves (a name, an address it missed) is one click to add: the text was already read, so the box snaps right on.
