Google widened access to one of Gemini’s most practical tools on April 17, 2026, by making Notebooks free for all web users. The feature, which debuted earlier this month for paying AI subscribers, lets anyone create a personal, unshared workspace inside Gemini. Users can stash conversations, uploaded files and external sources under a single topic, and Gemini automatically draws on that material when answering subsequent queries.

Inside the Gemini interface, Notebooks appear as a new section in the side panel, positioned between the Gems and Chats tabs. Any chat can be saved to a notebook via the three‑dot menu, turning ad‑hoc interactions into a reusable knowledge base. Users can also set custom instructions to shape the tone, format and style of Gemini’s replies, or disable notebook memory altogether if they prefer a clean slate for each question.

The real boost comes from integration with NotebookLM, Google’s standalone research application. Both platforms share the same notebook files, so a source added in Gemini instantly shows up in NotebookLM and vice‑versa. That seamless sync enables users to leverage NotebookLM’s video overviews and infographic tools without manual transfers.

Free users may add up to 50 sources per notebook. Subscribers to Google’s AI Plus plan receive a 100‑source cap, Pro users enjoy 300, and Ultra tier members can store as many as 600 sources. The notebook functionality supports Gemini’s full toolkit, including web searches and other AI‑driven features.

For now, the rollout is limited to the web version of Gemini. Mobile and Mac applications do not yet include Notebooks, though Google has hinted that broader availability is on the horizon. The expansion underscores Google’s push to make AI‑enhanced productivity tools more accessible, turning everyday users into power users without a subscription fee.
