NotebookLM

Google’s AI research assistant that grounds every response in your specific documents to eliminate hallucinations and provide cited insights.

NotebookLM leverages Google’s Gemini 1.5 Pro model to transform private documents into interactive knowledge bases. Users upload up to 50 sources (PDFs, Google Docs, or URLs) per notebook to generate summaries, study guides, and deep-dive Audio Overviews. The system maintains strict source-grounding: every claim includes a direct citation to the original text. It handles 500,000 words per source, providing a high-capacity tool for researchers and professionals managing complex datasets without the risk of generic AI fabrications.
