Google continues to develop NotebookLM with frequent feature additions, many still hidden. Recent weeks saw the addition of [infographics](https://www.testingcatalog.com/google-develops-infographics-tool-for-notebooklm/) and the ability to generate [slides](https://www.testingcatalog.com/google-works-on-slides-generation-feature-for-notebook-lm/). 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.
