The prompt
Build a glossary of the 20 most important terms in these sources. Term | Definition as used here | Source | Terms it is easily confused with Where authors define a term differently, keep both definitions and name the authors. Do not merge them into one. Use only the sources in this notebook. Cite the source for every claim. If the sources do not cover something, say "not covered in the sources" instead of filling the gap.
How to use it
- Open the notebook and tick only the sources this question is about.
- Paste the prompt into the chat and replace every part in [SQUARE BRACKETS].
- Open two or three citations in the answer to confirm they say what the answer claims.
- Save the answer as a note, then keep it: Export the glossary to CSV.
Adapt it
- Ask for the terms a beginner should learn first.
- Turn the glossary into flashcards.
NotebookLM can misread or over-generalise a source. A prompt reduces that; it does not remove it. Check cited passages before you rely on an answer.
Free or Pro?
Free, with no daily export quota and no website account needed. Pro covers the extension only; it does not include a Google subscription or raise NotebookLM's own limits. Current prices are on the pricing page.
