Google is preparing a notable expansion of its NotebookLM product, according to a newly emerging internal memo. This document outlines some upcoming features aimed at expanding the way users consume and share AI-generated content. Among the most anticipated updates is the addition of VIDEO Overviewcomplements existing text and audio formats. This move follows Google's multimodal development pattern across the Gemini ecosystem.
Updates also affect Studio Panelthe right sidebar currently hosting the project management tool. The panel has been slightly redesigned to accommodate these new content formats, suggesting a more rigorous integration of NotebookLM's creative and organizational capabilities. Users working withUIDO Overview Now you have the ability to create multiple artifacts in different languages in previously limited workflows within the same notebook.

Another important detail in the note highlights the more detailed sharing functionality. Users can share individual artifacts such as audio clips and mind maps without exposing the entire notebook. This addresses long-standing requests from users who rely on NotebookLM for collaboration or publishing projects, providing more control over the privacy and distribution of content.
These features aren't live yet, but recent updates to the web UI provide clues that the rollout may be near. The Audio Overview Customization popup has added a language selector to replace the hassle of having to toggle language settings across your project. This minor UI shift appears to lay the foundation for a full feature drop.
Part of Google Labs, Notebooklm is steadily evolving as an individual AI research assistant. Future changes will strengthen Google's focus on turning it into a modular tool for creators, academics and knowledge workers, and it blends well with the broader Gemini product direction. Given the timing of the leak and the already visible UI adjustments, these additions could reach production within the coming weeks.
