Gemini Notebook users can now copy entire notebooks, including all associated sources and studio items, if they have copy permission. This feature enables users to build upon shared work, like a student copying a teacher's notebook to add personal notes and generate study tools. Similarly, a coworker can duplicate a foundational notebook and customize it for a specific project by adding relevant sources. When a notebook is copied, its sources and studio content are transferred to the new user's library. Drive-based sources are only included if the copying user has access and permission to the original Google Drive file. Studio content, such as Audio Overviews, Video Overviews, Study Guides, Flashcards, Quizzes, Slide Decks, artifact generation prompts, and custom chat configurations, are all copied. However, personal chat history and user-generated notes are not transferred. Importantly, copied notebooks do not sync with the original; subsequent updates by the original owner will not affect the copied version. There is no admin control for this feature, but admins can manage Gemini Notebook access for users. End users, as notebook owners, can decide whether to allow others to copy their notebooks through the 'Allow copies' section in sharing settings, which is enabled by default. This feature is now available to all Google Workspace customers and users with personal Google accounts who have access to Gemini Notebook.
