Study software is the category that asks for an account first and explains why later. A flashcard app wants your email before it will save a card, a calculator site puts three adverts between you and the answer, and both are keeping something. Nothing on this shelf has a sign-up, because there is no server for an account to exist on.

It is also the shelf where working offline matters most. A page that has finished loading keeps running on a train, in a library basement and on a phone with no signal, which is more than can be said for most of what you would revise with otherwise.
