Google’s NotebookLM has recently gone viral, thanks to its Audio Overviews feature that creates lifelike podcasts from uploaded documents. This experimental tool is gaining attention for its ability to mimic natural speech, making AI-generated podcasts more engaging than typical text-to-speech outputs. Here’s how to try it out and create your own AI podcast.
What Is NotebookLM?
NotebookLM, part of Google Labs, is an AI-powered research assistant designed to summarize documents. Its standout feature, Audio Overviews, allows users to generate podcast-like summaries of their content. This feature simulates the conversational flow of real podcasters, complete with natural pauses, filler words like “um” and “oh,” and engaging delivery. Launched in 2023, the tool became even more popular after the release of Audio Overviews in September 2024.
Step-by-Step Guide to Creating an AI Podcast
To try out this new feature, follow these steps:
- Sign in to NotebookLM: Head over to NotebookLM and sign in using your Google account.
- Create a New Notebook: Once logged in, click New Notebook. You can upload up to 50 documents per notebook, including Google Docs, PDFs, Google Slides, or even public YouTube transcripts.
- Upload Source Material: Drag and drop files or link web pages and videos. Keep in mind that NotebookLM only analyzes the text from websites, not images or layouts, and it cannot handle paywalled content.
- Generate an Audio Overview: After uploading your content, open the Notebook guide in the bottom-right corner and navigate to the Audio Overview section. Click Generate and wait for the tool to process your documents. This may take a few minutes depending on the file size.
- Download or Share Your AI Podcast: Once your podcast is generated, you can download the file or share a link. You also have the option to adjust the playback speed if you want faster or slower audio.
Why Use NotebookLM for AI Podcasts?
NotebookLM’s Audio Overviews are a fun way to transform dense or complex information into engaging audio content. Whether you’re summarizing a corporate report, creating a study guide, or even crafting a casual discussion around a topic, this feature makes information more digestible.
Plus, the tool is free and easy to use, all you need is a Google login. It’s perfect for multitaskers who want to listen to content while performing other tasks.
The Privacy Factor
Google has addressed concerns about privacy, noting that personal data uploaded to NotebookLM isn’t used to train the tool’s AI models. This means you can use it for sensitive files without worry, provided you don’t share your content with collaborators.
The Future of AI-Generated Podcasts
The potential for AI-generated podcasts goes beyond simple document summaries. Users are getting creative, generating audio-based “deep dives” into niche topics or summarizing health routines and personal data. As the tool evolves, Google plans to add more customization options, such as controlling podcast length and topics, and possibly supporting more languages and accents.
While Audio Overviews won’t replace human podcasters anytime soon, real podcasters build personal connections with their audience, NotebookLM offers an exciting glimpse into the future of AI-assisted content creation. It’s not just a tool for summarizing data; it could become a standard feature for transforming written content into engaging, accessible audio.
