NotebookLM by Google is a free AI-powered research and note-taking tool that lets you upload documents, websites, and YouTube videos, then generates interactive summaries, audio overviews (AI podcasts), and video briefings grounded entirely in your sources. Powered by Gemini 3, it provides accurate Q&A with inline citations and refuses to hallucinate beyond your uploaded materials. Its Audio Overview feature has become particularly popular for turning dense documents into engaging podcast-style discussions.
