Gemini Notebook, formerly NotebookLM, is an AI-powered research and writing assistant developed by Google Labs. It functions as a personalized AI expert, working only with the information you provide it. Unlike general AI chatbots that pull from the vast internet, Gemini Notebook grounds its responses and insights in your uploaded documents, such as PDFs, Google Docs, Google Slides, website URLs, and even audio files. The tool can help you summarize, answer questions, generate ideas, and generate audio overviews about the ingested documents.

 Gemini Notebook acts as a "virtual research assistant" that helps you digest, understand, and synthesize information from your own materials.
