Google Brings Project Notebooks to Gemini With NotebookLM Sync

Google introduced notebooks in the Gemini app on April 8, 2026, giving users a dedicated place to organize project chats, files, and instructions around a single topic. The company described notebooks as personal knowledge bases that start in Gemini and sync with NotebookLM, extending the integration Google added late last year when NotebookLM became a source inside the Gemini app.

Users can create a notebook from Gemini's side panel, move earlier chats into it, add custom instructions, and upload documents or PDFs that give the model more context. Once those sources are collected, Gemini can use them alongside its native tools and web search to produce responses that stay grounded in the project's materials. Google also said notebooks sync in both directions with NotebookLM. A source added in one app appears in the other, which means users can start in Gemini and continue in NotebookLM without rebuilding the project. Google highlighted NotebookLM features such as Video Overviews and Infographics as examples of tools that can now be applied to notebooks created in Gemini. A student, for example, can collect class material in a notebook, use NotebookLM to generate a video overview, and then return to Gemini to draft an essay outline from the same source set.

Rollout details

The initial rollout starts this week on the web for Google AI Ultra, Pro, and Plus subscribers. Google said access will expand in the coming weeks to mobile, more European countries, and free users. The feature is not available for users under 18 or for Workspace and Education accounts. That staged release shows notebooks are being positioned as a premium workflow feature first, even as Google works toward broader availability.

The broader product signal is that Gemini is becoming a workspace for persistent research and execution, not only a chat window. By tying Gemini's conversational interface to NotebookLM's source-grounded workflow, Google is pushing its consumer AI products toward longer-running project management rather than one-off prompting.
