TL;DR
What did u/Ok_Negotiation_2587 use NotebookLM for?
Because NotebookLM is limited by its sources and tends to answer the nearest thing it can find, a user asks it to list the important questions the sources leave open and where they conflict, giving a research to-do list before the gap shows up in a report or exam. They get a to-do list of exactly which sources they still need, and say the disagreement check is the fastest way they've found to spot where NotebookLM is blending two sources into one smooth answer.
What they did
Before writing from a notebook, they ask: based only on these sources, list the important questions about the topic that they don't answer or only partly answer, say which source comes closest and what's missing, then list places where two sources disagree and nothing settles it. They run it once with all sources ticked and again with only the most trusted ones, and save the answer as a note to rerun after adding sources.

Worth knowing
- The creator also builds a browser extension for exporting AI chats, which they mention, but the prompt works on its own. The gap list is only as good as the topic knowledge behind it, so add your own questions too.

Based only on these sources, list the important questions about [topic] that they don't answer, or only answer partly. For each one, say which source comes closest and what exactly is missing. Then list any place where two sources disagree and nothing settles it.
