Google recently upgraded its AI note-taking and research tool, NotebookLM, with the addition of a 'Deep Research' tool that automates and simplifies online research. It offers two modes—'Quick' and 'Deep'—to cater to different research needs. The update also introduces support for various file types, including Google Sheets, PDFs, and Microsoft Word, allowing users to import Drive files in bulk by pasting URLs. Additionally, the upgrade expands visualization templates and multimodal output options, such as audio, video, and mind maps, enhancing the richness of information presentation. These features are now available to global paid users and Workspace enterprise customers.
