Just gave it a whirl and it works pretty good. It doesn't seem like you can force hashcards to let you re-review your deck at anytime though as its on a scheduler. (Imagine this is by design of SRS, but a bit annoying can't override with a flag).

I think uploading a textbook to NotebookLM and getting it to build out a deck for each chapter will be a great study method.
