Google NotebookLM

Google NotebookLM is a free AI research assistant from Google that is grounded entirely in sources you upload. Unlike general-purpose chatbots, it only answers based on your documents, making it ideal for deep research on specific materials.

• Source-grounded AI — Upload PDFs, Google Docs, websites, YouTube videos, and audio files; the AI answers exclusively from those sources
• Inline citations — Every AI response includes clickable citations linking back to the exact passage in your source material
• Audio Overview — Generate a podcast-style audio discussion of your sources, with two AI hosts conversing about the key themes
• Study guides and FAQs — Auto-generate study materials, briefing docs, timelines, and FAQ pages from your sources
• Notebook organization — Create multiple notebooks for different research projects, each with its own set of sources

Students use NotebookLM to study textbooks and lecture notes interactively. Researchers synthesize findings from multiple papers. Professionals prepare for meetings by uploading relevant documents and asking the AI to brief them.

NotebookLM never hallucinates beyond your sources — every answer is traceable. Access it free at notebooklm.google.
