NotebookLM

Google’s personal AI research assistant and interactive workspace, grounded strictly in user-uploaded materials (Source-Grounded AI). It avoids hallucinations: it answers questions only using the provided documents, videos, and notes, with precise citations. Google renamed NotebookLM to Gemini Notebook but kept it as a separate specialized product rather than a feature of the main Gemini chat.

What it can do and how to use it

• In-depth analysis of documents and videos. Upload PDFs, Google Docs, text files, audio, and direct YouTube links. Automatically extract key points, timelines, reference guides, and FAQs.
• Audio Overviews (audio podcasts). Turn dry documents and reports into engaging conversational audio breakdowns (podcasts) featuring two virtual hosts.
• Strict citations. Every AI claim comes with a clickable citation that links to the exact location in the source file or transcript.
• Visualization and learning. Create mind maps, cheat sheets, research guides, and study plans for exams or meetings.
• Isolated context. Up to 500,000 words per source; the number of sources and notebooks depends on your plan (see below).

Plans and pricing

Gemini Notebook is not sold as a separate subscription: limits are determined by your Google account plan. Basic access is free; paid Google plans and enterprise licenses offer higher limits. Limits are based on Google’s help documentation and may change.

The price of paid plans varies by country. For reference: Google AI Plus with 2 TB of cloud storage costs around $50 per year in Ukraine (about $4.2 per month at the exchange rate as of 10/30/2026). For current Pro and Ultra pricing, see Google’s plans: prices are not listed on the help page.
