NotebookLM is a tool that assists users in understanding complex information by summarizing and providing relevant citations to simplify the acquisition of knowledge. It now features a new option called 'Audio Overview,' allowing users to convert documents, slides, charts, and more into AI-generated audio discussions with just one click. These discussions not only summarize the content but also establish connections between topics and can be downloaded for on-the-go listening. Although Audio Overview is still in the experimental phase and has some limitations—such as generating audio overviews for large notebooks taking a few minutes, the AI host currently only explaining in English, and not allowing users to interrupt—it offers new ways for those who learn and retain information better through auditory dialogue.
