Google's AI note-taking and research assistant NotebookLM now lets users customize the tone of their Audio Overviews, which are podcasts with AI virtual hosts that summarize and discuss documents shared with NotebookLM, such as course readings or legal briefs. When generating an Audio Overview, users can now choose whether they want their AI podcasts to be formatted as a "Deep Dive," "Brief," "Critique," or "Debate."
Google announced on Monday that it updated NotebookLM's Video Overviews feature to support 80 languages, including French, German, Spanish, and Japanese. The company also upgraded Audio Overview, enhancing non-English audio summaries to be more detailed. Last month, NotebookLM launched Video Overviews so users could turn their notes, PDFs, and images into video presentations. Previously only available in English, this update is beneficial for non-English speakers who want to learn from visual summaries in their preferred language.
