Google · AI Research Assistant for Your Documents
Upload your own documents, PDFs, and notes and ask questions — NotebookLM answers with citations drawn only from your sources.
Best for
Researchers and students who need to ask questions about their own document collections with cited answers
Not ideal for
Discovering new sources, general web research, or tasks requiring information beyond your uploaded documents
Who it's for
Students and researchers who need an AI assistant grounded in their own document collections
NotebookLM is an AI-powered research assistant developed by Google that is grounded exclusively in the documents you upload. Unlike general AI assistants that draw on their training data, NotebookLM only uses the sources you provide — PDFs, Google Docs, web pages, YouTube links, or pasted text — and cites each answer with specific passages from those sources. This makes it well-suited for tasks where accuracy to a specific set of documents matters: research projects, studying, analysing reports, or navigating large document collections. Users can have an interactive conversation with their sources, generate summaries, create study guides, and produce audio overviews — a feature that converts source content into a podcast-style audio summary. NotebookLM is free to use with no subscription required. Its main limitation is that it is only as useful as the sources you put in — it cannot answer questions about topics you have not uploaded, and it is not a general research tool for discovering new information from the web.
