1. Define your research brief

• Write 3–5 sentences describing: what you want to learn, who the audience is, and what final deliverable you need (memo, script, strategy doc, deck, etc.).ingeniom+1
• Turn this into a single “master prompt” you will reuse in both your deep‑research tool (Gemini/Claude/etc.) and in NotebookLM so everything stays aligned.youtubecodecademy

2. Run deep research outside NotebookLM

• In your deep‑research tool, start a research job using your brief as the main prompt, and ask it to cover key subtopics with citations to diverse sources.youtube+1
• Have it output a long, structured report (sections, bullet points, references) that you can easily export or copy into another tool.aifire+1

3. Create a dedicated NotebookLM notebook

• In NotebookLM, create a new notebook named after your topic and reserve it only for this project so all sources and reasoning stay organized.codecademy+1
• Optional: add any existing PDFs, web articles, or YouTube URLs you already know you’ll need as additional sources now or later.blog+1

4. Import the deep research report as a source

• Export or copy your deep‑research report and add it to the notebook as a source document (e.g., Google Doc, pasted text, or uploaded file).linkedin+1
• Treat this as your primary research guide that aggregates multiple external sources, and always check its citations against originals when needed.ingeniom+1

5. Ask high‑leverage questions in NotebookLM

• Use NotebookLM chat to ask questions that go beyond summary: gaps, trade‑offs, competing views, implications, or explanations for different expertise levels.rits.shanghai.nyu+1
• Explicitly instruct it to ground answers in your imported report and other sources, and use the inline citations to jump back to the evidence passages.blog+1
