Why I Wrote This

The key to getting the most out of NotebookLM is the quality of your questions. Ask the right questions and it becomes more than a summarizer -- it becomes a research partner.

This post organizes all the topics I've recommended so far by category, bundled with practical templates showing how to frame questions that unlock real depth.

1) AI/LLM Infrastructure (Hands-On)

Recommended Topics

• Optimizing LLM long-context performance (KV Cache, Tiered Cache, Prefill cost)
• vLLM / serving optimization (throughput, TTFT, batching)
• Improving RAG quality (chunking, reranking, evaluation)

Example NotebookLM Prompts

• "Explain the root causes of model slowdown in long contexts from a structural perspective."
• "Compare KV cache optimization approaches across accuracy, cost, and latency dimensions."
• "List the top 10 bottleneck metrics we should measure first in our service, ranked by priority."

2) Middle East / Religion / Geopolitics (Balanced)

Recommended Topics

• Historical timeline of major Middle Eastern nations
• The Bible and Israel: separating historical, religious, and political perspectives
• Minimum background knowledge needed to understand global conflicts

Example NotebookLM Prompts

• "Condense modern Middle Eastern history into 10 turning points."
• "Explain religious narratives separately from geopolitical narratives."
• "Propose a framework for fairly comparing different perspectives."

Note: For sensitive topics, it is important to develop the habit of separating facts, interpretations, and opinions.

3) History Deep Dives (Korean History + World War History)

Recommended Topics

• Key inflection points in Korean history (ancient to modern to democratization)
• World War I and II: causes, progression, outcomes, and lessons

Example NotebookLM Prompts

• "Select 7 events in Korean history that had the greatest impact on today's social structure."
• "Create a comparison table of WWI and WWII, and connect them to the modern international order."
• "Reconstruct the narrative as an understanding-focused storyline, not an exam-prep outline."

4) Industry / Investment Research (Company Analysis)

Recommended Topics

• eVTOL: comparing Joby / Archer / Vertical Aerospace
• Hydrogen economy value chain + key players
• Palantir: revenue model, Ontology, and moat

Example NotebookLM Prompts

• "Break down each company's risks separately by technology, certification, and commercialization stage."
• "Map companies across the hydrogen value chain segmented by production, transportation, storage, and utilization."
• "Explain Palantir's Ontology not as a data model but as a 'decision-making operating system.'"

Note: Investment decisions are separate; this section is for structuring your research framework.

5) General Knowledge / Lifestyle (Broad Learning)

Recommended Topics

• Wine vs. whiskey: differences in production, aging, and tasting
• Mediterranean cuisine: ingredients, nutrition, and regional cultures
• Art history: movements from ancient to Renaissance to modern to contemporary

Example NotebookLM Prompts

• "Give me the 10 minimum concepts a beginner needs to distinguish between wine and whiskey."
• "Convert the Mediterranean diet into an actual one-week meal plan."
• "Design a beginner's course that covers all of art history through just 20 works."

6) Defense / Security Topics (Non-Tactical, High-Level Learning)

Recommended Topics

• Air defense concepts (the layers of detection, tracking, and interception)
• Generational evolution of fighter jets and tanks, and their operational doctrines

Example NotebookLM Prompts

• "Summarize the air defense system at a high level, as if explaining an architecture diagram."
• "Explain why generational changes occurred in fighter jets and tanks from a technology and battlefield environment perspective."
• "Exclude actionable tactical information and summarize only educational concepts."

7) Copy-Paste-Ready 'Universal Prompt Template'

아래 자료를 바탕으로 [주제]를 초심자도 이해할 수 있게 설명해줘.
(Based on the materials below, explain [TOPIC] so that a beginner can understand it.)

요구사항 (Requirements):
1) 먼저 5줄 요약 (5-line summary first)
2) 핵심 개념 7개를 정의 (Define 7 key concepts)
3) 타임라인 또는 비교표 1개 (1 timeline or comparison table)
4) 자주 생기는 오해 5개 (5 common misconceptions)
5) 실무/일상에서 써먹는 포인트 3개 (3 practical takeaways for work or daily life)
6) 추가로 읽을 자료 추천 10개 (왜 중요한지도 한 줄씩)
   (10 recommended readings, with a one-liner on why each matters)

주의 (Cautions):
- 사실/해석/의견을 분리해서 표시 (Clearly separate facts, interpretations, and opinions)
- 불확실한 내용은 불확실하다고 명시 (Mark uncertain content as uncertain)
- 과장 없이 균형 있게 작성 (Write in a balanced way without exaggeration)

8) Recommended Workflow (Maximizing Efficiency)

1. Start with 5-10 sources per topic
2. Progress in order: first summary, then deep-dive questions, then comparison for decision-making
3. Archive results immediately as blog posts or notes
4. Lock in retention with 3 review questions the next day

Conclusion

NotebookLM ultimately gets better the faster you can iterate on good questions. Use the topic list from this post together with "question templates + comparison tables + follow-up actions," and you can transform simple information consumption into your own knowledge system.

If you are interested, the next post can take one of the topics above and walk through an actual NotebookLM conversation log (question, answer, follow-up question) as a worked example.
