Google has expanded access to its “Notebooks” feature within the Gemini app, making it available to free users as part of efforts to broaden adoption of its AI-powered productivity tools.

Previously limited to paid subscribers, the feature now appears as a dedicated section within the Gemini interface, allowing users to organise content, store conversations, and manage research materials in a single workspace.

The Notebooks function is based on capabilities from NotebookLM and enables users to generate outputs such as summaries, infographics, and video-style overviews from collected sources.

Google said the feature is designed to act as a “personal knowledge base,” helping users consolidate files, chats, and references for long-term projects and research.

Within a notebook, users can access saved conversations and sources, while Gemini can draw context from all stored materials to provide more informed responses. There is also an option to disable this memory feature for more isolated interactions.

Free users can include up to 50 sources per notebook, while higher-tier plans offer expanded limits of up to 600 sources.

The feature is currently available on desktop, with mobile and Mac support expected in the coming weeks as Google continues to refine the experience.
