How to Use NotebookLM Audio Overviews

What Are Audio Overviews?

Audio Overviews are AI-generated audio conversations about your uploaded sources. NotebookLM creates a natural-sounding discussion between two AI hosts who explain, debate, and summarize the key points from your material.

Think of it as getting a personalized podcast episode about whatever you're researching — generated in minutes from your own sources.

How to Create an Audio Overview

1. Open your NotebookLM notebook with sources already uploaded
2. Click the "Audio Overview" button in the notebook
3. Select which sources to include (or use all)
4. Optionally add a focus prompt to guide the discussion
5. Click Generate — it takes 2-5 minutes depending on content length
6. Listen directly in NotebookLM or download the audio file

Using Social Content for Audio Overviews

Audio Overviews work with any source you upload — including PDFs converted from social media content. This opens up creative use cases:

• Thread deep dives — convert a viral X thread to PDF, upload it, and get an audio discussion that expands on the key points
• Newsletter summaries — convert 5-10 Substack newsletters to PDF, upload them, and get a podcast-style summary of the week's insights
• Expert roundups — collect LinkedIn posts from multiple experts on one topic and generate an audio discussion comparing their views
• Research briefings — combine articles and threads into an audio briefing you can listen to during your commute

Step-by-Step: Social Post to Audio Overview

1. Convert social posts to PDF using PostToSource
2. Create a new notebook in NotebookLM
3. Upload the PDFs as sources
4. Click Audio Overview and set your focus
5. Listen to AI hosts discuss the content from your social sources

Tips for Better Audio Overviews

• Use focus prompts — tell NotebookLM what to focus on: "Focus on practical frameworks and actionable advice" or "Compare the different perspectives on this topic"
• Curate sources carefully — 5-10 focused sources produce better audio than 30 random ones
• Mix source types — combine threads, articles, and newsletters for richer discussions
• Download and share — audio files can be shared with teammates who prefer listening to reading
• Iterate on prompts — if the first audio doesn't cover what you wanted, regenerate with a more specific focus prompt
