Google Enhances NotebookLM with Gemini 3 and Data Tables

Google has announced significant upgrades to its NotebookLM artificial intelligence platform, integrating the Gemini 3 model and introducing a new feature called Data Tables. This enhancement aims to improve NotebookLM’s reasoning capabilities and multimodal understanding, although specific details about the model used remain unspecified. The rollout began on December 19, 2025, with the new features available on the web and expected to reach mobile platforms in the following year.

The Data Tables feature allows users to synthesize information from various sources into structured tables, which can be exported to Google Sheets. This tool is designed to facilitate the organization of information, enabling users to create price comparison charts, compile meeting transcripts into actionable items, and aggregate research results across multiple studies. Notably, Data Tables can assist in preparing study materials by organizing historical events or planning vacations by comparing destinations and costs.
