Google Gemini Notebook Expert Intelligence turns purchased books into interactive AI sources

Google's Gemini Notebook now lets you talk to the books you've bought. The new Expert Intelligence feature pulls content from Google Play Books purchases directly into the Notebook, where you can ask questions, generate plans, infographics, or AI podcasts based on the material. For builders and publishers, this is a notable shift: it turns static e-books into interactive, queryable sources while keeping access controls tight and creating a new revenue channel for authors.

Turning purchased books into interactive AI sources

Expert Intelligence bridges Google Play Books and Gemini Notebook. When you bring a supported title into Notebook, you can ask questions about the content and generate outputs like a recipe book from Michael Pollan's "Food Rules" or get advice on handling a difficult conversation using Kim Scott's "Radical Candor". The full text of the book is viewable inside Notebook for the purchaser. More than 100,000 books from publishers like Penguin Random House, Johns Hopkins University Press, Macmillan, and O'Reilly Media support the feature at launch. Google also worked with 15 authors including Pollan, Scott, Steven Pinker, and Jennifer Wallace to create "Featured Notebooks" that include custom source material and intro letters.

What changes for builders and publishers

For AI builders, the key insight is a new pattern for integrating proprietary content into AI workflows. Instead of copying excerpts or building custom RAG pipelines over a single book, users can now treat their entire purchased library as a live source. Google plans to bring Expert Intelligence to AI Mode in Search and the Gemini app, and to expand coverage to scholarly articles, magazines, and newspapers. That broader rollout could matter for product teams building knowledge assistants or research tools that rely on licensed content.

Publishers and authors see a direct revenue opportunity. Each shared Notebook that references a purchased book sends non-owners to Google Play Books to buy the title. That's a cleaner model than the current norm of AI training data being scraped without compensation. Steven Johnson, Google Labs editorial director, described the goal as creating "new revenue possibilities for authors and publishers."

What you can actually do with Expert Intelligence

In practice, you can load a book into Notebook and ask specific questions about its content. The Notebook can also generate plans, infographics, and AI podcasts based on the material. If you share a Notebook with someone who hasn't purchased the book, they see the source listed and a link to buy it, but they cannot access the full text or any extracted information. This DRM-like protection is critical for publishers who want to enable AI interactivity without losing control over the underlying content.

Important limitations to note

Expert Intelligence is a new feature and may evolve. The planned expansion to other content types (scholarly articles, magazines, newspapers) is stated but not yet delivered. The feature currently requires a Google Play Books purchase, so it's limited to that ecosystem. There's no indication of a standalone API or builder-facing SDK yet, which means the immediate value is for end users, not for developers building third-party products. As with any vendor-reported launch, the actual capability and robustness will become clearer once builders start pushing it beyond the demo scenarios.
