Google is integrating Deep Research capabilities into NotebookLM, enhancing the source management interface to include web and Google Drive options. This feature aims to streamline research organization for users, particularly students and professionals, by providing in-depth, contextually relevant information. Additionally, a new "tutor" mode is being planned to support interactive learning, further enhancing the educational utility of NotebookLM.

NotebookLM has expanded its Audio Overviews feature to support over 50 languages, allowing users to generate engaging audio content in their preferred language. This enhancement, powered by Gemini's audio capabilities, enables multilingual content creation and enhances accessibility for diverse audiences. Users can easily switch languages in their settings to create tailored educational resources.

NotebookLM introduces public sharing for notebooks, allowing users to create and share links easily with anyone. This feature enhances collaboration by enabling viewers to interact with the content through questions and generated materials, although editing remains restricted. Currently, public sharing is limited to personal accounts, while Workspace and Education accounts have domain restrictions.
