What is Google NotebookLM?
NotebookLM is Google's free AI research tool that lets you upload PDFs, Google Docs, websites, and other sources, then interact with them using AI. Unlike ChatGPT, it only uses information from your uploaded sources—no hallucinations, just answers grounded in your materials.
