NotebookLM now lets you listen to a conversation about your sources

We built NotebookLM to help you make sense of complex information. When you upload your sources, it instantly becomes an expert, grounding its responses in your material with citations and relevant quotes. And since it's your notebook, your personal data is never used to train NotebookLM.

Over the summer, NotebookLM expanded globally and used Gemini 1.5's multimodal capabilities to power new features, such as Google Slides and web URL support, better ways to fact-check, and the ability to instantly create study guides, briefing docs, and more.

Today, we're introducing Audio Overview, a new way to turn your documents into engaging audio discussions. With one click, two AI hosts start up a lively "deep dive" discussion based on your sources. They summarize your material, make connections between topics, and banter back and forth. You can even download the conversation and take it on the go.

It's important to remember that these generated discussions are not a comprehensive or objective view of a topic, but simply a reflection of the sources that you've uploaded.

To try it out, follow these steps:

1. Open an existing notebook
2. Open your Notebook guide
3. Click on the "Generate" button to create an Audio Overview
