NotebookLM is a Google AI-powered research and writing assistant that works best with the sources you upload. It's an experimental AI that allows you to upload PDF and text files for processing. The AI then generates various outputs such as FAQs, study guides, and briefing documents. It has the ability to create a 10-minute long podcast-style conversation between a man and a woman, discussing the uploaded documents.
As an example, check out the results from an 1897 article from The Strand Magazine about unusual competitions held in London's East End. The AI-generated podcast show is astonishingly good! Also, you can now add public YouTube URLs and audio files to your notebook, for an even deeper understanding of your sources.
