oosync vs NotebookLM
NotebookLM is Google’s free research assistant: you add sources and ask questions about them, and it can produce audio overviews. It is excellent and free, so the honest question is what you need on top. oosync is built around a course: modules, a study routine, notes you write, practice and your class.
