bounding box
A rectangle of coordinates marking where something sits in an image or on a page.
A bounding box is just a rectangle described in numbers: this far from the left, this far from the top, this wide, this tall. It is how software says “the thing you asked about is right here” about a spot in an image or a document.
That sounds trivial and it is what makes AI document answers checkable. If a tool reads a hundred-page contract and tells you the notice period is three months, a bounding box is what lets it also highlight the exact sentence on page 43 that it took the answer from. Without one, you get a claim and no way to verify it, which in practice means either blind trust or reading the contract yourself.
