NotebookLM to get Data Tables artefact, Deep Research to be released soon

Google continues to develop NotebookLM with frequent feature additions, many still hidden. Recent weeks saw the addition of infographics and the ability to generate slides. The latest hidden artefact, Data Table, allows users to compose structured tables for data comparison. This feature is positioned for those handling diverse data sources and could serve both enterprise clients and individual users requiring organized data extraction.

The Slides feature now supports further customization through a settings menu, offering language selection and custom prompts for generation control. Google’s approach is to provide direct outputs in various artefact forms, aiming to deliver tangible results for users.

NotebookLM’s product direction indicates a focus on expanding research methods. A new announcement highlights upcoming options for sourcing and researching, pointing to two previously discovered modes: fast and deep research.

Fast research is currently active, resembling the app’s existing search but integrated into an updated interface. Deep research is referenced as a future upgrade, where the feature is expected to work similarly to Deep Research in Gemini.

Additional changes include a filter for managing multiple sources and a video transcript download option. This allows users, particularly content creators, to repurpose video transcriptions, including for YouTube descriptions. Such tweaks streamline working with multimedia and large datasets.

These features, still in restricted testing or not broadly released, fit Google’s ongoing strategy for NotebookLM: a modular toolset for direct result delivery, with growing emphasis on structured data, customization, and robust research support. This positions NotebookLM as a versatile platform for both business and personal productivity. Google has not issued an official statement on the precise launch timing of these upgrades.
