Gemini Notebook grounds answers in 100,000 books

Google launched Expert Intelligence in Gemini Notebook with access to more than 100,000 books from major publishers, letting users query purchased Google Play Books titles and receive cited answers, the company says. The ownership gate is the product’s real business detail: collaborators must buy their own copy before a shared notebook can use the book, preserving a rights boundary rather than turning every upload into a communal corpus. Builders watching grounded assistants should track this distribution move alongside Google’s cheaper Gemini workhorse: trusted licensed sources are becoming a product surface, not just a retrieval backend.
