Google announced exciting updates to its AI note-taking and research assistant, NotebookLM. These enhancements allow users to summarize YouTube videos and audio files, as well as create shareable AI-generated audio discussions. The company originally launched it at the I/O developer conference last year. NotebookLM has since expanded its reach to markets including India, the U.K., and over 200 countries following its public access debut in the U.S.
Shifting User Demographics
Initially popular among educators and learners, NotebookLM has recently attracted a significant number of business professionals. Raiza Martin, a senior product manager for AI at Google Labs, noted that the user base is now roughly split, with 50% being educators and learners, and the other half consisting of business professionals. She mentioned, “People are now sharing notebooks, and it’s creating a network effect,” highlighting the growing collaborative nature of the tool.
Google Audio Overview and Sharing
Earlier this month, NotebookLM introduced the Audio Overview feature. In addition, it will enable users to transform their documents into engaging audio discussions. The latest update expands this functionality by allowing users to share the generated Audio Overview via a public URL. Users can easily click on the share icon to obtain the URL. Additionally, they can share it with others.
Google Support for YouTube and Audio Files
NotebookLM has added support for YouTube videos and audio files (such as .mp3 and .wav) as new source types. This enhancement allows users to summarize key points from YouTube videos. In addition, they can extract insights from audio recordings of their study sessions or projects. The tool support various formats, including Google Docs, PDFs, text files, Google Slides, and web pages.
User Feedback Drives Development
Martin emphasized that the small team behind NotebookLM relies heavily on user feedback to guide the development of new features. She noted, “What’s interesting about AI tools is that a lot of assumptions change,” indicating that users’ needs can evolve rapidly.
Global Expansion and Usage Insights
Since its initial launch in the U.S., Google has expanded NotebookLM’s access to over 200 countries. The majority of usage remains in the U.S. However, Japan has emerged as a significant market for the tool. Martin observed that many users in Japan are utilizing NotebookLM to summarize documents in languages different from the tool’s default settings, showcasing its versatility.
Google Privacy and User Responsibility
Google assures users that the information uploaded to NotebookLM remains private. Additionally, they will not use it to train AI models. Users must be at least 18 years old to access the tool. However, Martin acknowledged the challenges associated with AI tools, such as the risk of users becoming overly reliant on them. As a result, it will potentially lead to a decline in reading long-form content. To mitigate this, NotebookLM provides clickable citations from the content users upload, encouraging deeper engagement with original texts.
Future Developments
Currently, NotebookLM is available for web access. However, Martin hinted that mobile apps may be on the horizon next year. The team is actively working on adding more features. In addition, they are focusing on enhancing input support and expanding output sources.
