NotebookLM helps you understand anything. If you’ve used NotebookLM before, you’ve manually uploaded sources for your projects — whether you’re writing a paper, planning a vacation or transcribing interviews. But starting today, there’s a new option: Discover sources.

When you tap the Discover button in NotebookLM, you can describe the topic you’re interested in, and NotebookLM will bring back a curated collection of relevant sources from the web. You can add those sources to your notebook in one click. It’s a fast and easy way to quickly grasp a new concept or gather essential reading on a topic.

How it works

When you describe your topic, NotebookLM gathers hundreds of potential web sources in seconds. It analyzes them and picks the most relevant ones based on your defined topic. It presents up to 10 source recommendations, each with an annotated summary explaining its relevance to your topic.

With one click, you can import these sources and use them with other NotebookLM features, such as Briefing Docs, FAQs, and Audio Overviews. The sources will remain in your notebook, allowing you to also read the originals, ask questions via chat, and use NotebookLM's citation and note-taking features.

We've even included a fun additional feature for newcomers to NotebookLM: the “I'm Feeling Curious” button. It generates sources on a random topic, offering a quick way for you to see the product’s source discovery agent in action.

Here’s how you can use it:

Discover sources is the first of a series of NotebookLM features that uses the power of Gemini to find and collect relevant sources for your notebook. It will start rolling out today for all NotebookLM users, and we expect the rollout to take about a week or so.
