AI research notebook grounded in your docs
NotebookLM is a source-grounded AI research and note-taking tool by Google that turns your documents (PDFs, Google Docs, websites, YouTube videos, and audio files) into interactive knowledge bases. It generates podcast-style audio overviews, video summaries, study guides, flashcards, quizzes, and slide decks from your sources. Every response is grounded in your uploaded materials with citations to minimize hallucinations, and it runs on Google's Gemini 3 model.
