What Is NotebookLM?
NotebookLM is an AI-based research and note organization tool developed by Google. Based on materials uploaded by the user, such as documents, PDFs, and web links, AI understands the content and performs summarization, organization, and question answering. It is close to a personalized AI research assistant.
Unlike conventional chatbots that answer based on general knowledge, its core feature is that it finds evidence and answers only within the materials provided by the user.
