NotebookLM

Google's AI research notebook that answers only from your own documents — cited, checkable, and hallucination-resistant.

NotebookLM — Google's AI research notebook that answers only from your own documents — cited, checkable, and hallucination-resistant. Pricing: Free; Plus $4.99/mo; Pro $19.99/mo; Ultra from $99.99/mo (paid access rides on Google AI plans). Our take: The best way to turn a pile of your own documents into cited answers, reports, and podcast-style briefings. Free is genuinely enough for most people; pay Pro at $19.99/mo only when you outgrow 50 sources per notebook. Renamed Gemini Notebook (July 2026) but the product is the same.
