Details
Notebooks launch in Gemini app as persistent project knowledge bases
Accessible via a 'New notebook' button in the Gemini app's side panel. Users can add documents and PDFs, move past chats in, and set custom Gemini instructions per notebook. Gemini uses the uploaded sources alongside its tools and web search to provide contextual responses.
Bidirectional sync between Gemini and NotebookLM
Any source added in the Gemini app automatically appears in NotebookLM and vice versa. This lets users leverage NotebookLM-exclusive output features — Video Overviews and Infographics — from work started in the Gemini app, bridging two previously separate Google AI products.
Source limits gated by subscription tier; rollout starts with paid web users
The number of files and sources per notebook scales with the user's Google AI subscription plan (Ultra, Pro, Plus, or free). Web launch begins this week for paid tiers; expansion to mobile, additional European countries, and free users is planned for coming weeks.
Product Launch = new feature release; New Tech = new capability or integration; Industry Update = rollout/availability or business move
What This Means
For users, notebooks reduce the friction of managing ongoing AI-assisted projects by creating shared context that persists across sessions and syncs between Google's two main AI apps. For Google, the feature deepens integration between Gemini and NotebookLM, making both products stickier and giving paid subscriptions a concrete productivity advantage over the free tier.
