Google’s AI notetaking goes rogue: Books are the next frontier for agentic knowledge extraction

Google just quietly launched a quiet revolution in how AI agents ingest and repurpose knowledge. With its new 'Expert Intelligence' feature in Gemini Notebook, the search giant is letting AI agents pull information directly from purchased books on Google Play Books—and then turn that content into custom plans, infographics, podcasts, and even interactive Q&A sessions.

It’s a stunningly simple idea with explosive implications. For the first time, AI agents aren’t just synthesizing public web data—they’re tapping into commercially sold intellectual property, transforming it into derivative content, and distributing it back to users. In effect, Google is turning every purchased book into a training dataset for AI agents, with no express permission from authors or publishers.

This isn’t just a feature—it’s an inflection point in how AI agents interface with proprietary knowledge. Google’s move raises urgent questions: What does it mean when AI agents can mine, remix, and republish copyrighted material at scale? Who owns the output when an AI generates a recipe from a cookbook or a synopsis from a novel? And more importantly, what happens to the value of original content when AI agents can extract, summarize, and redistribute it on demand?

The implications ripple across industries. Publishers face a potential erosion of revenue streams as AI agents make books redundant as standalone products. Educators must rethink how knowledge is curated and credited in the age of AI-mediated learning. And consumers? They gain unprecedented access to synthesized insights—but at what cost to creators?

This is more than a tool upgrade. It’s the first major step toward a world where AI agents don’t just assist in knowledge retrieval—they own it. Google isn’t just building a notetaking app. It’s building a knowledge extraction engine that treats books as raw material for AI agents to exploit. The question now isn’t whether this will scale—it’s whether it should.
