NotebookLM prompt: compare methods across papers
Short answer
Use it when studies reach different results and you suspect the methods explain why. Paste the prompt below into the NotebookLM (Gemini Notebook) chat and replace the parts in square brackets. It tells NotebookLM to answer only from your sources, cite them and flag what they do not cover.

The prompt
Compare how the sources study [PHENOMENON]. For each source describe: how the key variable is defined and measured, the design, the sample, and the analysis. Then explain which differences in method could account for differences in findings. Mark each explanation as stated by an author or as your inference. 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 to LaTeX.
Adapt it
- Ask whether results are comparable at all, and why or why not.
- Request a one-paragraph summary for a methods section.
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.
Frequently asked questions
What should be in the notebook before I use the compare methods across papers prompt?
Papers that study the same phenomenon.
Why does the prompt ask NotebookLM to say what is not covered?
Because a grounded tool is most useful when it shows the edges of your sources. An explicit instruction to flag gaps reduces confident answers that the sources do not support.
Does this prompt work in Gemini Notebook?
Yes. Gemini Notebook is the new name of NotebookLM since July 16, 2026. The chat works the same way: it answers from the sources you select.
