Google Adds Voice Conversations, Audio Recording and Interactive Learning Overviews to Gemini Notebook

Google is rolling out new Gemini Notebook features that turn the former NotebookLM into a more voice-driven study workspace, adding real-time spoken conversations with notebooks, mobile lecture recording and interactive learning overviews. The update, announced on September 15, also expands quizzes and short video summaries as Google tries to make source-grounded AI work across phones, reports and classroom material rather than only text chat.
