NotebookLM upgrades enhance research with AI

Google's NotebookLM research tool has received substantial upgrades, including enhanced reasoning capabilities powered by Gemini models and a secure cloud computer for code execution. Users can now initiate research projects with basic ideas, as the tool actively helps find and organize relevant web sources. The update also introduces the ability to generate diverse file formats like charts, spreadsheets, and slide decks directly within the application. These advanced features are now available globally to users with Google AI Ultra and specific Workspace business accounts.
