Two big steps towards our vision for @NotebookLM as the ultimate research platform: • Integrating Deep Research, with a set of only-at-Notebook features that let you explore the retrieved sources • Launching a series of Featured Notebooks curated by @GoogleResearch These developments are designed to enhance the full life cycle of research and scholarship: using the power of AI to assemble the knowledge base you need to advance your understanding, and then making your work accessible and intelligible to a wider audience using all the explanatory tools that Notebook offers. If you've used DeepResearch in the Gemini app, you already know that it's a pioneering advance in assembling complex, grounded information on any topic imaginable—collecting an entire trove of material for you and writing a nuanced research report that summarizes the findings. But because NotebookLM is designed to manage and explore potentially hundreds of sources, the Deep Research report is only the beginning of your journey. In our integration, Deep Research gives you an overview all of the sources it found during its research phase, with annotated commentary explaining how each source related to your original query. You can then choose to import some or all of the sources to the notebook, along with the report itself, which you can then explore or transform using the full suite of tools that Notebook offers: grounded chat with citations, Mind Maps, Audio/Video overviews, and much more. And it's that suite of tools that make the @GoogleResearch Featured Notebooks so compelling as well. Each notebook contains a curated collection of articles on a specific topic, published by the Google Research team. Think of them as a kind of knowledge base of Google's best thinking on a series of compelling research questions: How do scientists link genetics to health? How will quantum computing be useful? If you're a specialist in these fields, you can read the original papers or ask nuanced questions in chat and advance your understanding of the latest developments. But these notebooks can also make the complex but important topics understandable to non-specialists or students. Each notebook comes with pre-generated audio and video overviews, flashcards, and other Studio artifacts designed to make the scientific and technological concepts accessible and interesting. And you can always explore the material with our new "Learning Guide" chat mode that effectively gives you a personal tutor to enhance your understanding. There's much more to come on this front, but you can see in these two announcements how we see Notebook as both a workbench for conducting research and a publishing platform for sharing the results of that research once you're ready to make it public. Deep Research is rolling out this week to all users. The first two Google Research notebooks are live now, both of them deep dives into our most recent discoveries involving genetics and health. (Links in the following tweets.) We'll be publishing new notebooks in the series every other week or so for the next few months.

For most users, @NotebookLM is a tool for understanding and exploring project-based information. But we also think it could be a distribution platform, amplifying expert knowledge. Today we're offering a preview of that vision: Featured Notebooks. Here's the backstory... In a way, all of this dates back to a conversation I had with @joshwoodward in late July of 2022, one of the very first I had in Mountain View after joining Google Labs. We were talking about an idea that had come to us through the work of @kevin2kelly: the concept of "intelligence as a service" that he'd written about many years before—AI that you could tap into on demand like electricity or water. I told Josh that I'd always thought that sounded like a fascinating prospect, though I’d struggled to imagine what it would look like in practice. But what we'd seen with language models, and particularly the source-grounded language models that we were starting to experiment with, had suddenly made it clear to us both how Kelly's intelligence-as-service might actually work, how it might actually give authors and publishers a new platform to share their wisdom with the world. "We're going to be able to bottle up the knowledge of experts," I said at some point. "And then people will just have that expertise on tap." Somehow the metaphor stuck: Knowledge bottles. At some point that fall, our then-designer @gabeclapper created a mock for a future page where you could purchase and download expert collections of knowledge; we called it, irreverently, "the Bottleshop." (It looked quite a bit like the design we are launching today for Featured Notebooks, as it turns out.) I kept encountering the phrase in meetings over the next year, as it spread around Labs and other parts of Google. And every time I would say: love the concept but please don't lock in on "knowledge bottles" as the official name. It was just a passing metaphor! Naming aside, the underlying premise only grew more compelling over time. General purpose models trained on aggregations of human information were incredibly useful, but imagine how much more useful they would be if they were guided by (or were guides to) knowledge that had been peer-reviewed, edited, researched by experts—knowledge that had a particular point of view. If you're looking for parenting advice, say, you don't just want the average of all parenting advice across the internet, you want parenting advice from a specialist who you trust. There was another reason why we were interested in this approach. The experience of using NotebookLM is heavily influenced by the quality of the sources you've curated in each notebook. There's literally nothing to do in the product until you load a source, and it can take time to assemble a truly rich notebook on a particular topic. Source curation (or context engineering, as we would now call it) is not something that the average user is familiar with. So being able to showcase notebooks with high-quality sources on a range of topics was important for us just to explain how the product works. So you can think of the Featured Notebooks we are launching today as a preview on two levels. For newcomers to NotebookLM, the notebooks are a preview of how useful the product can be when you've assembled a collection of sources for whatever project you're working on. But it's also a preview of a potential future where there are thousands of expert-curated notebooks on all sorts of topics that you can add to your own collection, to have the knowledge you need on tap. Our launch lineup is: Longevity advice from legendary scientist @EricTopol, bestselling author of “Super Agers” Expert analysis and predictions for the year 2025 as shared in The World Ahead annual report by @TheEconomist An advice notebook based on bestselling author Arthur C. Brooks' "How to Build A Life" columns in @TheAtlantic A science fan’s guide to visiting Yellowstone National Park, complete with geological explanations and biodiversity insights An overview of long-term trends in human wellbeing published by the University of Oxford-affiliated project, @OurWorldInData Science-backed parenting advice based on psychology professor Jacqueline Nesi’s popular Substack newsletter, Techno Sapiens The Complete Works of William Shakespeare, for students and scholars to explore A notebook tracking the Q1 earnings reports from the top 50 public companies worldwide, for financial analysts and market watchers alike In the blog post announcing the notebooks, there's a wonderful quote from @nxthompson, CEO of the Atlantic, that really captures the spirit of what we're trying to do here: "The books of the future won’t just be static: some will talk to you, some will evolve with you, and some will exist in forms we can’t imagine now," Nick said. "We’re delighted to partner with Google in its pioneering work on this front.” It's the adaptability of the notebook format that I think makes this such a compelling platform for sharing knowledge. You can read the original texts in their entirety; you can ask questions or brainstorm ideas through a conversational interface, with citations pointing you back to the relevant passages from the original sources. Students or novices can ask for simpler explanations of complex topics, or listen to Audio Overviews or review Study Guides to help them master the material. But experts can ask more challenging questions, or quickly assemble the information they need. And all of the conversational interactions can unfold in over 80 languages, no matter what language the original sources were written in. We are making these notebooks freely available to all users, either because they involve public domain information or because we have secured world rights for the material from the original authors or publishers. This is still very much an experiment, and there are many elements that we would like to improve over time. You can't generate your own studio artifacts, like Audio Overviews or Study Guides, in featured notebooks; all the artifacts have been pre-generated. Chat can be in any language, but the artifacts themselves are English-only for now. While we have tried to focus on topics that will have global relevance, the initial lineup is more U.S.-focused; if these turn out to be useful to people, we plan to diversify in terms of both language, region, and topics. The best way to get a sense of what "bottled knowledge" actually feels like in practice is to open one of these notebooks and ask for advice: ask for a sample itinerary for a 3-day trip to Yellowstone focused on wildlife, or ask for advice on a making a mid-life career change in the "How To Build A Life" notebook from The Atlantic; or ask the experts at The Economist about how global economic trends might impact your industry. I think you'll find that the results are genuinely helpful, and maybe offer a hint of a new way of interacting with an author or publisher's work. And if you have ideas for future versions of featured notebooks, please let us know!
