Google has expanded Gemini Notebook with Expert Intelligence, an initiative that lets users ground notebook interactions in trusted content, beginning with eligible ebooks they own through Google Play Books.
The update makes books usable alongside a user's own materials, allowing Gemini Notebook to generate responses and learning artifacts based on the combined sources.
For teams that need to turn authoritative material into usable guidance, the change offers a more source-centered way to work with AI.
According to Google's official Expert Intelligence announcement, the initial catalog includes more than 100,000 books from major publishers.
Google describes the effort as a cross-Google initiative developed with authors and publishers, with broader availability planned over time across additional sources and platforms, including the Gemini app and AI Mode in Search.
How Expert Intelligence works in Gemini Notebook The initial implementation is centered on books purchased through Google Play Books.
A user can add a supported ebook to a Gemini Notebook, then use the book's content as a source for notebook interactions.
Google says the notebook can combine that material with the user's own documents and other sources.
That distinction matters.
This is not simply a general prompt asking Gemini to summarize a title from its training.
The workflow is designed to use the content of a book the user owns as part of the notebook's source material.
Google presents that approach as a way to engage with trusted content while preserving the link between access and ownership.
From source material to usable artifacts Google says Expert Intelligence can create several kinds of outputs from a book's content, either on its own or in combination with a user's materials: Answers grounded in the book Infographics Audio overviews Quizzes Other notebook artifacts The company's example involving Steven Pinker's The Sense of Style illustrates the intended use: a writer can bring the book into a notebook with a draft and use the book's guidance while working on the draft.
More broadly, a user could combine a relevant title with internal notes or project materials to support a writing, strategy, or learning task.
Source type in Gemini Notebook How it is used Access condition described by Google User's own materials Can be combined with book content in notebook interactions No additional condition is specified in the announcement Eligible Google Play Books Can ground answers and generated artifacts The user must own the book through Google Play Books Ownership is central to sharing Expert Intelligence has an important limitation for collaborative notebooks.
Google states that a collaborator who receives a shared notebook must also own the relevant Google Play Book to continue engaging with that book's content.
Sharing the notebook does not give another person access to the book itself.
For businesses, that means access management remains part of the workflow.
A manager cannot assume that a single book purchase will enable every colleague to use its contents in a shared notebook.
Teams that want to build repeatable research or training workflows around a title will need to account for who owns the underlying book.
Google's announcement does not provide a separate price for Expert Intelligence.
The confirmed requirement is ownership of the eligible title through Google Play Books, so the direct cost information available is tied to acquiring the book rather than to a stated standalone feature fee.
Why the update is useful for knowledge work The practical value is in connecting AI outputs to material a user has deliberately selected.
A business might use a book on writing, management, strategy, or another relevant subject alongside internal working documents, rather than relying only on a broad model response.
Gemini Notebook can then help convert that material into formats suited to a particular task, such as an overview for review, a quiz for learning, or a
