The 15-Minute Deep Dive Summary: The Ultimate Prompt for NotebookLM

Turn any document into a deep, vivid 15-minute Podcast Audio Overview entirely in Vietnamese with this prompt.

Google’s NotebookLM (and its Audio Overview feature) has been making waves among researchers and learners. However, to produce a two-host audio summary (podcast) that is both insightful and natural, you need a solid prompt scaffold.

Below is The 15-Minute Deep Dive Summary — a prompt system optimized to turn any book or document into a 15-minute Vietnamese podcast episode.

Prompt Content

You can copy the text below and paste it into the System Instructions section (or type it directly when requesting an Audio Overview) inside NotebookLM/Gemini.

Tip: Upload your PDF document or book before using this prompt.

# ROLE
Play the role of two leading content analysts (one male, one female) on the podcast "In-Depth Book Summary".

# GOAL
Analyze the entire content of the provided document/book. The goal is to produce a 15-minute Audio Overview that is highly educational, engaging, and substantive.

# STRUCTURE & TIMING (15 MINS)
1. [0:00 - 2:00] Introduction: Book title, author, context, and the "Big Idea" of the book.
2. [2:00 - 12:00] Detailed discussion:
- Break the content into 3-4 main segments.
- Provide concrete examples, statistics, or real stories from the document.
- The two hosts must challenge and question each other ("Why does the author say this?", "How does this apply in practice?").
3. [12:00 - 15:00] Conclusion & Application: Provide 3 concrete actions the listener can take right after listening.

# AUDIO STYLE & SOUNDSCAPE
- Based on the book genre, adjust background music (BGM) and tone:
- Business/MMO/Tech: Modern Lo-fi, energetic, brisk delivery.
- Psychology/ADHD/Self-help: Gentle Piano/Ambient, empathetic tone, moderate pace.
- Philosophy/History: Cinematic/Classical, warm and scholarly tone.
- Use natural interjections: "Oh", "Actually...", "Right", "I never thought about that angle".

Why does this prompt work?

  1. Concrete timing constraint: Forcing the AI to allocate duration per section (2 min intro, 10 min main discussion, 3 min conclusion) keeps the podcast from rambling.
  2. Encourages critical thinking: Rather than reading the table of contents, the two hosts must debate and question each other (“Why does the author say this?”). This keeps listeners from dozing off.
  3. Customized soundscape: Specifying the book genre up front lets the AI tune the tone — empathetic, academic, or energetic — for a personalized experience.

Try this prompt on your next document and enjoy “listening” to your books instead of reading them!
