In addition to the chatbot functionality, NotebookLM can use the source data to build FAQs, briefing summaries, and, of course, Audio Overviews—that’s a podcast-style conversation between two fake people, a feature that manages to be simultaneously informative and deeply unsettling. It’s probably the most notable capability of NotebookLM, though. Google recently brought Audio Overviews to its Gemini Deep Research product, too.
And that’s not all—Google is lowering the barrier to entry even more. You don’t even need to have any particular goal to play around with NotebookLM. In addition to the Discover button, Google has added an “I’m Feeling Curious” button, a callback to its iconic randomized “I’m feeling lucky” search button. Register your curiosity with NotebookLM, and it will seek out sources on a random topic.
Google says the new NotebookLM features are available starting today, but you might not see them right away. It could take about a week until everyone has Discover Sources and I’m Feeling Curious. Both of these features are available for free users, but be aware that the app has limits on the number of Audio Overviews and sources unless you pay for Google’s AI Premium subscription for $20 per month.
