Very interesting, would likely be useful for general knowledge.
However, when you are learning a very narrow field of study, the app does not create great suggestions. A complicated example, but see the following:
"Choroidemia patients have a normal electroretinogram"
presents: MRI, Melee, Moon, DNA.
Of course, I don't expect it to come up with something amazing for something that GPT-3 or other language models aren't trained on.
