NotebookLM can now use uploaded audio and YouTube videos as sources 

Earlier this month, Google launched Audio Overviews in NotebookLM that turn your notes into a podcast. The latest NotebookLM update lets you use audio files and YouTube videos as sources. 

At the moment, you can upload PDF, .txt, and Markdown files to NotebookLM, as well as directly paste text. Webpages, Google Docs, and Google Slides can also be used as one of your 50 sources.

NotebookLM will now let you upload audio files (like .mp3s or .wavs) and videos on YouTube. (Gemini does not let you upload audio or video yet.) Example use cases in NotebookLM include:

  • Analyze video essays and lectures: Easily summarize key points and arguments from educational YouTube content.”
  • Make group projects and discussions more productive: Capture key takeaways and insights from study sessions and team projects by uploading your audio recordings to NotebookLM.”
  • Turn class recordings and handwritten notes into study guides: Upload your own recordings of lectures and presentations for easy review and analysis. Upload your handwritten notes as well.”

Meanwhile, you can now share Audio Overviews as links. This feature, which generates a back-and-forth discussion with AI hosts, has been quite popular for presenting summaries and connections in a natural manner that even includes banter.
