Google Launches Expert Intelligence in Gemini Notebook

Google is turning purchased books into grounded AI sources

Google announced Expert Intelligence on August 27, 2026 as a new cross-Google initiative starting in Gemini Notebook. The launch lets users add eligible ebooks they already own through Google Play Books to a notebook, then ask questions or create outputs grounded in the book alongside their own notes, files and other sources.

The distinction that matters is availability. The book integration is live now for eligible titles in Gemini Notebook, while broader Expert Intelligence support in the Gemini app and AI Mode in Search is still planned for later.

What is available now

Google says Expert Intelligence launched with more than 100,000 books from publishers including Bloomsbury, De Gruyter Brill, Johns Hopkins University Press, Macmillan, O'Reilly Media and Penguin Random House.

For eligible books, users can add the title to Gemini Notebook and ask questions against the book as a source. Google also highlights Notebook features such as infographics, Audio Overviews and quizzes that can be generated from the material.

A notebook can combine a purchased book with other sources, including the user's own information. That makes the feature more than a book-chat interface: it is designed to let people compare or apply a trusted authored source alongside their own context.

Rights controls are part of the product design

Google says access is tied to ownership through Google Play Books. If a notebook containing an Expert Intelligence-enabled book is shared, collaborators who do not own the title are prompted to purchase their own copy before they can continue interacting with that book inside the notebook.

That detail is important because generative-AI products have repeatedly raised questions about how copyrighted material is licensed and used. Expert Intelligence is being positioned as a product in which access to the protected source is connected to an existing commercial entitlement rather than simply exposing an unrestricted copy.

What is still upcoming

Google says Expert Intelligence is starting with books in Gemini Notebook. The company plans to extend the initiative to the Gemini app and AI Mode in Search, and says additional source types such as third-party subscriptions, business research reports and textbooks are expected later.

Those future integrations should not be confused with the launch state today. As of the announcement, the concrete released experience is the eligible-book workflow in Gemini Notebook.

Why this matters

The release points toward a broader model for AI products built around licensed, user-authorized expert sources rather than only open-web retrieval or generic model knowledge.

For students, professionals and researchers, the practical value is source grounding: answers can be tied to books the user has actually purchased, while still being combined with personal documents or other notebook sources.

For publishers and authors, the more consequential part may be distribution. Google explicitly describes Expert Intelligence as a way to help people engage more deeply with paid content and says it has been developed with participating authors and publishers.

The launch is therefore less about a new foundation model and more about a new content-rights and retrieval layer for consumer AI. It could become more important if the same entitlement-aware pattern expands into subscriptions, research reports, textbooks, Search and the Gemini app as Google says it intends to do.
