Inclusion rule. Tools whose own page says what the question asks about. Order. Alphabetical by tool name.
Few pages give a maximum, and the ones that do measure different things: a video's running time, an episode's length, or a kind of prose. None of them promises that a long draft stays consistent all the way through; that has to be checked in the draft.
For short-form tools the ceiling is usually a few minutes, set by the format rather than by the writer.
