Google's NotebookLM is a popular AI-based note-taking service that can collect documents, URLs, audio files, and other content for any type of research. After you submit your source files, the AI is able to analyze, summarize, discuss, and answer questions about them.

But one especially cool feature is the ability to take your source files and generate an audio overview in the form of a podcast. The audio features two AI-generated people conducting a natural conversation about the topic at hand. With pauses and uhs and ums and overlapping speech, the podcast sounds just like two real human hosts discussing the subject. 's David Gewirtz covered his experience with the tool in depth and you can check out his surprisingly lifelike AI podcast samples here.

You can then use the podcast as part of a presentation or demonstration on your topic. Just be sure to tell your audience that it's AI-generated. You can also publicly share it. But even if you keep the podcast private, listening to it can be a helpful way to gain more insight and understanding into your subject. And instead of just reading the summaries and analyses generated by NotebookLM, hearing the podcast is a more interesting and entertaining way to soak up the material.

For now, the podcasts are available only in English. Since the feature is AI-generated and still in the experimental stage, you may find inaccuracies and audio glitches. But it's still amazing to see and hear how AI can create something that sounds so human. Now, here's how this all works.

1. Browse to the NotebookLM website

2. Upload your source files

You're prompted to upload your source files. For this, you're able to upload PDFs, text files, markdown files, and audio files such as MP3s and WAVs. You can also grab the content from different sources, including your computer, Google Drive, and pasted text. 

Either drag and drop the files you wish to use or choose the source and select the files to include. You can add as few as one file and as many as 50.

4. Generate the podcast

By default, all the files are checked and will be included in the summary. Uncheck any files that you don't want to incorporate. After you've lined up your source files, NotebookLM automatically generates a text summary of the uploaded files. When you're ready for the podcast version, click the Generate button. In some cases, you may have to select Notebook guide at the bottom and then click Generate.

5. Play the podcast

Depending on how much source material you uploaded, creating the podcasts will take anywhere from several seconds to several minutes. You can always busy yourself with other work (or play) while the audio is being generated. Once it's ready, you'll see a Play button with a slider and a number indicating the length of the audio. Click the Play button to start listening, and the podcast kicks off.

6. Control the podcast

7. Name the notebook

8. Rate the podcast

Do you like the podcast or think it could be better? Either way, you're able to rate the podcast by clicking the thumbs up or thumbs down icon just above the slider. If you opt for a thumbs down, you're asked to provide a reason for your negative response.

9. Share the podcast

If you think other people will like the podcast, you can share it publicly. Click the Share icon and then turn on the switch for Public access. Preview the podcast to see and hear how other people would access it. To proceed, click the button for Copy share link and you now have a URL to send to anyone who might like to listen to the audio.

11. Download the podcast

You can save the podcast from the same menu. Choose Download and you're prompted to save the podcast as a WAV file, letting you listen to it via any media player such as Windows Media Player, iTunes, or VLC Media Player.

12. Customize a podcast

By default, NotebookLM uses its own AI-based skills and knowledge to create your podcast. But you can direct or tweak a podcast by adding instructions on what you want. To try this, add your sources and allow them to be incorporated. Instead of clicking the Generate button, click Customize.

13. Add your instructions

15. Access your podcasts

To return to the main NotebookLM screen, click NotebookLM at the top left of the screen. You'll then find all the podcasts you've generated. Click a specific podcast to load and play it. Click the three-dot icon and you can change the title or delete the podcast entirely.
