Google's Expert Intelligence grounds Gemini Notebook answers in Play Books you own

Google has expanded Gemini Notebook with a feature called Expert Intelligence, which lets users ground the assistant's answers in published ebooks they own through Google Play Books. According to dev.to, citing Google's announcement, the launch catalog spans more than 100,000 titles from major publishers, and Google describes the project as a cross-Google effort built together with authors and publishers.

How the integration works

The workflow differs from asking Gemini to summarize a book from memory. A user adds a supported ebook to a Gemini Notebook, and its contents then act as source material for that notebook's queries. Google says the book can be used on its own or blended with the user's own documents and other sources already in the notebook. Access also stays tied to ownership: a title works as a source only for someone who has bought it on Google Play Books.

What Gemini can produce from a book

According to dev.to, Google says the notebook can generate several kinds of output from a grounded book, either alone or in combination with a user's materials:

• Answers grounded in the book
• Infographics
• Audio overviews
• Quizzes
• Other notebook artifacts

Google's worked example involves Steven Pinker's The Sense of Style: a writer loads the book into a notebook next to a draft and leans on the book's advice while revising. The same pattern could pair a relevant title with internal notes or project files to support a writing, strategy, or study task.

Sharing comes with a catch

Collaboration has a notable limitation. Google states that anyone who receives a shared notebook must also own the relevant Google Play Book to keep working with that book's content, so sharing a notebook does not hand over access to the underlying title. For teams, that means one purchase will not cover a whole group, and any workflow built around a specific book has to account for who actually owns it. The announcement listed no separate price for Expert Intelligence; the stated requirement is simply ownership of the eligible title.

Featured Notebooks and expansion plans

Google is also preparing curated Featured Notebooks with authors including Steven Pinker, Michael Pollan, and Jennifer Wallace, according to dev.to. The company presents books in Gemini Notebook as a starting point rather than the final scope, with broader availability planned over time across additional sources and platforms, including the Gemini app and AI Mode in Search.

Why it matters

Grounding AI output in sources a user deliberately selected addresses a common criticism of chatbots: answers that cannot be traced to reliable material. By letting the model work from the exact text of a book the reader paid for, Google positions Gemini Notebook as a tool for structured research, writing, and learning rather than open-ended chat. The design also gives publishers and authors a channel into AI products that respects purchases, and the ownership requirement for shared notebooks sets an early precedent for how rights-cleared content may be handled as similar retrieval features spread across Google's apps.
