Introduction

What is Google Notebook LM?

Google Notebook LM is a free AI‑powered research assistant from Google. You upload your source materials – documents, PDFs, web articles, YouTube transcripts – and it becomes an expert on those sources. You can then ask questions, get summaries, and even generate entire podcast scripts based on your curated content.

Unlike generic chatbots, Notebook LM grounds its answers only in the sources you provide, making it perfect for creating factual, well‑researched podcast episodes. It's like having a personal research assistant and scriptwriter rolled into one.

Key Features
• Upload up to 50 sources per notebook
• Ask questions and get answers with citations
• Generate outlines, summaries, and full scripts
• Free to use with a Google account

Step 1

Set Up Your Notebook LM Project

1. Go to notebooklm.google and sign in with your Google account.
2. Click "New notebook" and give it a name (e.g., "AI Podcast – Episode 1").
3. Upload your sources. You can add:
   • Web articles (paste URLs)
   • PDFs and Google Docs
   • Copy‑pasted text
   • YouTube video transcripts
4. Aim for 3‑5 high‑quality sources per episode for focused, accurate output.

Once your sources are added, Notebook LM processes them and becomes ready to answer questions and generate content based on exactly what you've fed it.

Pro Tip For a single podcast episode, collect sources that represent different viewpoints or aspects of the topic. This gives your script depth and makes the conversation more engaging.

Step 2

Generate Your Podcast Script with AI

Now the fun begins. Use Notebook LM's chat interface to create your episode script. You can ask it to write a full script in your preferred format. Here are two powerful prompts you can copy and paste:

Notebook LM Prompt

Write a 10‑minute podcast script based on the sources I've provided. The podcast is hosted by two people, Alex and Sam, who have a friendly, conversational tone. 
Structure:
- Intro (30 seconds) – welcome and topic overview
- Main discussion (7 minutes) – cover 3 key points from the sources
- Outro (1 minute) – summary and call to action
Include natural transitions, occasional humor, and mark each speaker's lines clearly with ALEX: and SAM:.

For a solo podcast, use this prompt instead:

Solo Podcast Prompt

Write a 10‑minute solo podcast script based on the provided sources. The host is knowledgeable but approachable, explaining complex ideas in simple terms. Include a strong hook in the first 30 seconds, 3 main sections with clear takeaways, and end with a question for the audience.

Notebook LM will generate a complete script with citations referencing your sources. Review the citations to verify accuracy.

Step 3

Refine & Polish Your Script

AI‑generated scripts are great, but always need a human touch. Read through the script and make these adjustments:

• Add personality: Insert your own anecdotes, catchphrases, or inside jokes that make your podcast unique.
• Break up long monologues: Add listener questions or rhetorical pauses to keep the flow natural.
• Adjust timing: Read the script aloud and trim sections that feel too long. Aim for 120‑150 words per minute of speech.
• Add audio cues: Mark places for music transitions, sound effects, or sponsor breaks.

You can also ask Notebook LM to shorten or expand specific sections. For example: "Make the intro more dramatic" or "Add a story about how this technology started".

Fact‑Check Always verify any statistics or claims from the AI against your original sources. Notebook LM is powerful but not infallible.

Step 4

Turn Your Script into Audio with AI Voices

Now the magic – convert your written script into spoken audio without ever touching a microphone. The best free tools for this are:

• TTSOpenAI.com – High‑quality voices (Nova, Fable, Shimmer). Free, no login. Paste your script and download the MP3.
• ElevenLabs – Ultra‑realistic AI voices (free tier: 10,000 characters/month). Great for a professional podcast feel.
• NaturalReaders – Simple online tool with adjustable speed and tone.

For a two‑host podcast, generate separate audio files for each speaker using different voices. For example, use Nova for Alex and Fable for Sam. This makes the conversation feel authentic.

Voice Settings for Podcast

Host Alex: Voice "Nova" – Speed 0.95 – Pitch +1%
Host Sam: Voice "Fable" – Speed 1.0 – Pitch 0%
Narrator/Intro: Voice "Shimmer" – Speed 0.9 – Pitch +2%

Download each voice track as an MP3 file. You'll combine them in the editing stage.

Step 5

Edit Audio & Add Background Music

Use a free audio editor to piece everything together. Audacity (free, open‑source) or CapCut (free, browser‑based) work perfectly.

1. Import all voice MP3 files into the editor.
2. Arrange them in the correct order according to your script.
3. Trim gaps between speakers and remove any mistakes.
4. Add background music at low volume (15‑20%) – use free sources like Pixabay Music or YouTube Audio Library.
5. Add intro/outro jingles or sound effects for a professional finish.
6. Normalize the audio levels so all tracks sound consistent.

Export the final episode as an MP3 file (128kbps is standard for podcasts).

Pro Tip Create a template in Audacity with pre‑placed intro music, outro, and sponsor slots. This way, each new episode is just drag‑and‑drop the voice tracks.

Step 6

Publish & Promote Your AI Podcast

Your podcast is ready! Here's how to get it to listeners:

• Spotify for Podcasters: Free hosting, automatically distributes to Spotify, Apple Podcasts, and Google Podcasts. Just upload your MP3.
• YouTube: Create a simple video with your podcast audio and a static image or waveform animation. CapCut can generate this automatically.
• Social Media: Share 60‑second clips on TikTok, Reels, and Shorts to attract new listeners.

Write compelling episode titles and descriptions with relevant keywords. Consistency is key – aim for at least one episode per week. As your library grows, so will your audience.
