How to Turn Your Documents into Audio Summaries with NotebookLM

What you need

• A Google account. The sources say a Google login is all you need to try Audio Overviews, and that the feature costs nothing to use.
• Some documents to work with, such as Google Docs or Slides files. You can also add website links or YouTube links.
• A web browser, and headphones or speakers for listening.
• About ten minutes for a first try. Larger collections take longer to process.

Example: imagine you are planning a four-day trip. You might keep your itinerary in a Google Doc, save a few pages about hotels and local transport, and add one public video about the destination. The audio overview then gives you a spoken recap you can play while you pack or commute. This is only an example to show the workflow.

Step by step

1. Sign in to your Google account. Use the account you want to keep these notes under. The sources describe signing in to a personal account, so start there.
2. Go to the NotebookLM website. Open it in your browser once you are signed in.
3. Click the plus arrow labelled New Notebook. This creates an empty notebook where your sources will live.
4. Add your documents. You can bring in Google Docs and Slides directly. Each notebook can hold up to 50 source documents.
5. Add website or YouTube links if you want them. Only the text of a web page is analysed, not its images or layout, and paywalled stories will not work. For YouTube, the tool uses the transcript, and the video must be public.
6. Open the Notebook guide. It sits in the bottom-right corner of the screen.
7. Find the Audio Overview section and click Generate. The tool creates a discussion-style audio version of your sources.
8. Wait for the audio to load. The sources say this can take a few minutes, depending on how much material you added. Be patient.
9. Listen to the result. Play it through once to check that it covers what you expected.
10. Share or save it. You can create a shareable link to the audio, or download the file.
11. Adjust the playback speed if needed. The sources mention an option to speed the audio up or slow it down.

Tips and common mistakes

• Keep notes clear and well organised. A tidy document gives a clearer summary than a messy one. For example, a simple trip note might look like this:

Trip plan: 4 days by the coast
Day 1: Arrive by train, check in, walk the harbour.
Day 2: Boat trip in the morning, free afternoon.
Day 3: Museum and market visit.
Day 4: Pack, leave by 3 pm.

• Do not expect a perfect first result. Listen to the whole overview and compare it with your originals before relying on it.
• Check your links before you add them. Paywalled articles and private YouTube videos will not give the tool what it needs.
• Watch the source limit. A notebook holds up to 50 documents, so split very large projects into several notebooks.
• Do not assume the audio is up to date for you. It only reflects the sources you uploaded. If a source is out of date, the summary will be too.
• Expect the feature to change. The coverage describes NotebookLM as carrying an experimental label, so menus and options may move around.

Use it responsibly

• Check the answers. An audio summary can miss details or word things loosely. Compare it with the original documents before you act on it, especially for travel bookings, health, money or school work.
• Protect your privacy. Do not upload private or sensitive files, such as passport scans, bank statements or medical records. Google says personal data in your sources is not used to train NotebookLM. Sources stay private unless you choose to share them with collaborators, so only share what you intend to share.
• Keep your account secure. Use a strong, unique password and do not share your login. Sign out on shared computers.
• Follow your rules. If you use NotebookLM for work or school, check your organisation’s policies first. Also follow the service’s own terms for how you may use the tool and the audio it creates.
