Google Upgrades NotebookLM with New Gemini 3.5 Model

Google has announced a significant update to its AI research assistant, NotebookLM, which now leverages the Gemini 3.5 model. The tool has gained new capabilities for handling complex tasks, including an improved chat with transparent decision-making logic and enhanced data analysis features.

Key innovations include support for over 100 pre-set "skills" for generating diverse outputs, as well as the ability to execute code in a secure cloud environment. NotebookLM can now create and export data in various formats: from visualizations (PNG, SVG) and documents (PDF, DOCX) to structured tables (CSV, JSON) and presentations (PPTX).

The updated tool simplifies the process of gathering sources: users can start with scattered ideas, and NotebookLM will help find relevant materials through Google Search integration. Each source is clearly attributed, increasing trust in the results. The new features are already available to Google AI Ultra subscribers and Workspace enterprise clients.

Developers emphasize that the update expands practical use cases: from analyzing international datasets and preparing reports to converting technical documentation into presentations and guides. The tool can also assist small businesses in analyzing financial data for strategic decision-making.
