3 Key Points

What happened
GoogleはAI研究ツール「NotebookLM」を「Gemini Notebook」に改称すると発表しました。製品の基本的な位置づけは変わりませんが、Geminiアプリ内に統合され、Googleのエコシステム全体で主要機能が利用できるようになります。
Why it matters
NotebookLMは2023年のGoogle I/Oで発表され、3000万人以上のユーザーが60以上の業界で使用しています。ユーザーがアップロードしたWebページやドキュメントに基づいてAI分析や要約を行う独自の機能を備えており、学習や研究に適しているため、ビジネスと教育の両分野で有用性が高いと考えられます。
What to watch
改称と同時に、6月のアップデートでクラウドコンピュータが各ノートブックに統合され、AIがコード記述・実行できるようになります。このアップデートは「Google AI Ultra」ユーザー、「AI Ultra Access」および「AI Expanded Access」付きWorkspaceユーザーに提供され、その後数週間でWeb Pro ユーザーに展開予定です。チャート、スプレッドシート、スライド、PDFなど複数形式への対応も追加されます。

Context & Analysis

NotebookLM has grown significantly since its announcement as "Project Tailwind" at Google I/O 2023. Unlike general-purpose chatbots, it anchors responses to user-provided sources—uploaded documents or web pages—making it suited for research, learning, and professional analysis. The tool has accumulated a substantial user base of over 3 million across diverse sectors, reflecting demand for grounded, source-based AI assistance.

The rename to Gemini Notebook signals Google's strategy to position this specialized tool within its broader Gemini AI platform. By integrating it into the Gemini app ecosystem and bundling key features across Google's product suite, the company aims to make notebook-based AI research more accessible to Workspace users. The June update introduces technical depth—cloud-backed code execution—that expands the tool beyond document analysis into development workflows. This move suggests Google sees Gemini Notebook not as a standalone product but as a component of its larger AI assistant offering.
