How does NotebookLM work?

Users can upload their own documents, such as PDFs, Google Docs, web pages, and YouTube videos, and NotebookLM then analyzes this content to form the basis of all responses. From there, users can ask questions, request summaries, and generate study guides, all grounded in their uploaded sources.

What types of files can I upload?

Can NotebookLM answer questions outside my sources?

No, NotebookLM only uses information from your uploaded sources unless you specifically ask for creative content, such as requesting a poem about a topic. If a question goes beyond the scope of the sources, NotebookLM will indicate that it cannot provide an answer.

How do I ask questions in NotebookLM?

To ask questions in NotebookLM, users can type their question in the chat input box at the bottom of the screen, use suggested questions found in the Notebook Guide, or click “View Chat” for a full chat interface.

Can I save or organize my notes and responses?

Can I use NotebookLM for business or training?

Yes, NotebookLM is useful for various business and training purposes, including onboarding new hires, developing training and policy documentation, enabling sales, and conducting research and strategic planning.

Is my data private and secure?

Your sources and notebooks are private unless you choose to share them, and NotebookLM does not train its models on your uploaded data, ensuring security.

Why can’t NotebookLM answer my question sometimes?

NotebookLM might not answer a question if it is outside the scope of your sources, if the source content triggers safety flags due to sensitive topics, or if the question itself is too vague or unclear.

How can I get better answers?

To get better answers, users should ask clear and specific questions, use suggested questions as a starting point, and try different formats like summaries, timelines, or FAQs.

What are some advanced features?

Some advanced features include the ability to generate mind maps, timelines, tables, and study guides, create audio and video overviews, and compare and contrast multiple sources.
