What really freaked me out is that it can take a story you've been talking about back and forth and produce story structure breakdowns in a huge variety of formats. You can make it give you three act, five act, save the cat, it's astounding. You can make your own revisions and it will be like, "oh, I see you moved the revelation about the phone call to the midpoint of act 2, that makes sense because blah blah blah"
