What is NotebookLM
NotebookLM is an AI-powered assistant designed to help users dive deeper into their knowledge resources. Powered by the Gemini 1.5 model, NotebookLM is more than a typical note-taking app. It lets users upload documents, PDFs, and even web-based content like articles or YouTube videos, creating a central knowledge hub. This hub then offers insights, helping users identify patterns, clarify complex concepts, and generate summaries.
Beyond organizing information, NotebookLM’s ability to convert notes into audio files is ideal for students, professionals, and especially educators. Faculty can use this feature in classrooms to create audio summaries, helping students review and engage with material at their own pace.

Audio Overview: A Closer Look
NotebookLM’s audio capability takes written content and transforms it into an engaging audio overview, perfect for multitasking. Here’s how this feature enhances the learning experience:
- Natural, Conversational Style: NotebookLM’s audio files aren’t robotic; they’re designed to sound natural and conversational. This makes for a listening experience that feels approachable, as if a knowledgeable guide were walking you through the material.
- Customizable Focus: Users can now tailor the audio content to emphasize particular points or sections, directing the AI to cover topics in more or less detail based on personal preference. This customization allows for more efficient learning, helping listeners stay focused on relevant content without unnecessary repetition.
- Great for Background Listening: The audio files can be played in the background while you work within NotebookLM, enabling you to listen as you review or edit your notes. This background capability is especially helpful for users who like to revisit material while working on related projects.
- Enhanced Accessibility: The audio feature is a game-changer for anyone who prefers auditory learning or faces challenges with reading. By turning text into audio, NotebookLM ensures information is accessible to all, providing an inclusive option for different learning styles.
Example
Turning a Gardening Infographic into an Audio Overview with NotebookLM
To demonstrate NotebookLM’s audio overview, I used a gardening infographic I created for a faculty member. By uploading the infographic into NotebookLM, NotebookLM generated a tailored audio summary that captures the main points of the content.
Below, you’ll see the infographic and the corresponding audio file created by NotebookLM, showcasing how visual information can be effectively translated into an audio format.
