NotebookLM goes global with Slides support and better ways to fact-check

Google Labs has expanded NotebookLM, its AI-powered research and writing assistant, to over 200 countries and territories, using the upgraded Gemini 1.5 Pro model. The update adds support for Google Slides and web URLs as sources, along with inline citations that link directly to supporting passages so users can fact-check responses. It also lets users ask questions about images, charts and diagrams in their sources. Product Manager Raiza Martin describes uses ranging from author Walter Isaacson analyzing Marie Curie's journals to Palm Bay resident Thomas Gaume running a hyperlocal newsletter.
