Google has updated its note-taking AI, NotebookLM, to include the ability to read information from websites and Google Slides, and users can now ask questions about charts, images, and diagrams. The new Notebook Guide also creates study guides or briefing documents, and inline citations can point to sources. NotebookLM is powered by Gemini 1.5 Pro, the latest large language model that currently powers the paid version of the Gemini chatbot.
