Personalized source-grounded research notebook & audio summaries
NotebookLM is a personalized AI research assistant built by Google. Unlike general chatbots, NotebookLM grounds all responses strictly within your uploaded sources (PDFs, Google Docs, slides, web URLs, YouTube videos). Its groundbreaking Audio Overview feature synthesizes your notes into a natural two-host conversational podcast breakdown.
