Google's AI-powered research and note-taking tool, NotebookLM, now allows users to customize the tone and style of its AI-generated 'Audio Overviews.' This update means business leaders can tailor how the platform summarizes and discusses shared documents, from technical manuals to project briefs, through a podcast-like format featuring virtual AI hosts.
The new functionality introduces four distinct formats for these audio summaries: 'Deep Dive,' 'Brief,' 'Critique,' and 'Debate.' A Deep Dive offers an extensive, conversational exploration with two AI hosts, designed for thorough understanding. A Brief provides a concise, quick overview of essential information, perfect for fast comprehension of core concepts.

Further customizing the experience, a 'Critique' format delivers a review of the source material with constructive feedback, while a 'Debate' presents differing viewpoints on the content via two AI hosts. Users can also control the length of these AI podcasts and select from new voice options for the virtual presenters, making the information consumption process more adaptable to specific needs and preferences.
This enhancement builds on recent NotebookLM developments, including the introduction of 'Video Overviews' for visual presentations and the launch of dedicated mobile apps. Rolling out this week across all languages, these advancements highlight a clear industry trend toward highly personalized and versatile AI tools designed to streamline the digestion of complex, business-critical information for industrial and operational leaders.
