Gemini Notebook (NotebookLM)

What it does

Google renamed NotebookLM to Gemini Notebook in July 2026; the product itself stays a standalone research tool. You create a notebook, add sources such as PDFs, websites, YouTube videos, audio or pasted text, and then ask questions answered from those sources. It can also generate study and presentation material: Audio Overviews (podcast-style summaries), flashcards, quizzes, infographics and slide decks. Google says notebooks can now be created and synced from the Gemini app, and that each notebook is getting a cloud computer able to run code for data analysis, first for Ultra subscribers and eligible Workspace customers, then for Pro users on the web. It works in the browser, and mobile apps exist for Android (version 10 or later) and iPhone/iPad.

Pricing and plans

The standard tier is free with a Google account and allows 100 notebooks of up to 50 sources each. Higher limits come through Google AI subscriptions: Plus (200 notebooks, 100 sources each), Pro (500 notebooks, 300 sources) and Ultra (up to 600 sources per notebook). On Google's US subscription page, Google AI Plus costs $4.99 per month, Pro $19.99 per month and Ultra starts at $99.99 per month; these plans also include other Google services. Qualifying Workspace licences unlock the same tiers. Prices and availability vary by country and may exclude tax.

Strengths and limits

Because answers draw on the sources you supply, it suits structured study and document review better than open web search. Limits apply: a single uploaded file is capped at 200 MB and 500,000 words, copy-protected PDFs cannot be imported, and the mobile app still lacks notes, mind maps, reports and data tables. Users must verify their age in their Google account, paid tiers depend on Google AI plans being offered in the user's region, and a visible watermark is added automatically in India, South Korea and Vietnam.
