Google’s NotebookLM updates Audio and Video Overviews

Google’s NotebookLM is expanding Video Overviews to 80 languages while upgrading Audio Overviews in all supported languages to match the comprehensive depth previously available only in English. Video Overviews provide concise video presentations of notebook content, helping users understand key concepts from sources like lectures or tutorials in their preferred language. Audio Overviews in non-English languages now offer full-length discussions that synthesize ideas across sources rather than quick highlights, with shorter overview options still available. These updates roll out to all NotebookLM users starting today, removing language barriers that previously limited insight quality from the AI research tool.​​​​​​​​​​​​​​​​
