About NotebookLM

NotebookLM is an AI research and note-taking tool from Google. Users add their own sources, such as documents, and the assistant analyzes them to answer questions, summarize material and help make sense of complex topics, keeping responses tied to what the uploaded material actually says.

Google's site now presents the product under the name Gemini Notebook, describing it as a research tool and thinking partner that turns complexity into clarity and helps transform content into new forms. It is widely known for generating spoken audio overviews of source material, alongside written summaries and cited answers.

NotebookLM is a hosted, proprietary Google service with no self-hosted version. It suits students, researchers, writers and analysts who want to question a fixed set of documents, and Google lists plans on a dedicated pricing page.
