We recently learned that Google was prepping a new feature that would allow users to ask Gemini questions about their NotebookLM notebooks. Although Google still hasn’t made anything official, this feature now appears to be rolling out to users.
According to recent X posts from Sai Nemani and TestingCatalog, the attachment menu in Gemini on the web now includes a NotebookLM button. This option lets users attach a notebook and ask Gemini questions about the attached notebook to get more relevant responses.
TestingCatalog reports that the feature lets users attach multiple notebooks as sources. In addition, the NotebookLM integration works with Gemini Gems, meaning users can create custom AI assistants with expertise on the information in their NotebookLM notebooks.
Gemini’s NotebookLM integration begins rolling out on the web
At the moment, the NotebookLM integration appears to be limited to the web version of Gemini. The attachment button is not available in the Gemini for Android on any of our devices. Availability also seems limited overall, with several users reporting that the feature has yet to appear on their Google accounts.
Google may expand access in the coming days and eventually bring the NotebookLM attachment button to the Gemini app for mobile, but there’s no confirmation yet. An official announcement with more details could be right around the corner.
Over the last few weeks, Google has introduced several major upgrades for NotebookLM, including support for additional file types, such as Google Sheets, Drive files, images, PDFs, and Microsoft Word documents, along with a significantly larger context window, longer conversational memory, and improved response quality. The NotebookLM mobile app has also picked up several improvements, including support for flashcards and quizzes, as well as broader chat improvements that first rolled out on the web version.
