NotebookLM

NotebookLM is a research and study assistant from Google that works only from the sources you give it. You upload documents, slides, PDFs, links or notes, and it answers questions, summarises and builds study material grounded in that material with citations back to the original text. Students, researchers, analysts and writers use it to understand large document sets quickly.

Key features

• Answers grounded strictly in your uploaded sources, with inline citations to each passage.
• Automatic summaries, briefing documents, timelines and FAQ generation.
• Study guides and quiz-style questions produced from your own course material.
• Audio Overview, which turns a notebook into a spoken discussion you can listen to.
• Support for PDFs, Google Docs and Slides, websites, pasted text and media transcripts.
• Notebook sharing so a team or study group works from the same source set.

Who it is for

• Students revising from lecture notes, textbooks and papers.
• Researchers working through a large literature or document review.
• Analysts and consultants digesting reports before a deadline.
• Writers organising interviews, research and reference material.

Pricing

NotebookLM is free to use with generous limits, and higher usage caps and extra features are available through Google's paid AI subscriptions. Current details are published on the NotebookLM website.

Why people choose NotebookLM

Searches for an AI tool that summarises your own PDFs accurately usually end here because NotebookLM refuses to wander beyond the sources provided, which sharply reduces invented detail. The citation-first design plus audio overviews makes it especially popular for revision and for teams who need to trust where an answer came from.
