We recently launched precisely this - a note-taking app that lets people add questions/identify salient terms for review as flashcards, and ML that applies those questions to auto-generate fill-in-the-blank for any written material.
Thank you, this is very close to what I was hoping for. I tested it out, and if I were in a position to pay for the premium features, I would highly consider it. However, the biggest stopgap for me is that my daily driver phone is a Samsung Note8, which of course means that I'm unable to use NoteFuel for the kind of spur-of-the-moment note-taking that would allow me to transition from Evernote (or else simply add it to my routine).
I would love to hear from you guys when an Android app is available.
Would love to hear any feedback you have. The app is called Notefuel: https://apps.apple.com/us/app/notefuel/id1458567718
