Google is rolling out NotebookLM integration within Gemini, allowing users to attach notebooks for real-time data access during conversations. This feature supports multiple notebook attachments and provides in-line citations for easy navigation to content. The update aims to enhance Gemini's functionality for both free and paid users.

NotebookLM has introduced a new "Discover sources" feature that allows users to find curated web sources by describing their topic of interest. This feature provides up to 10 relevant source recommendations with annotated summaries, making it easier for users to gather information for their projects. Additionally, an "I'm Feeling Curious" button offers random topic suggestions to showcase the source discovery capabilities.
