Leveraging a cutting-edge model from the Google Gemini family, NotebookLM empowers users to extract quick summaries from extensive documents. This rapid ability to both synthesize and generate information proves invaluable, particularly during the research process. While previously, users had to upload documents manually to gain insights, that challenge has been alleviated with NotebookLM’s innovative Discover Sources feature, which autonomously finds research sources across the internet.
Steps to Effectively Use the Discover Sources Feature
To kick off your research journey with the Discover Sources feature, start by navigating to the NotebookLM website in your preferred web browser.
If this is your first time accessing NotebookLM, you will need to log in via your Google account. Once you’re logged in, initiate a new project by clicking on the Create New button.

In the pop-up menu that appears, locate and select the Discover Sources button positioned at the top right corner.

You will be presented with a prompt requesting a brief description of your research topic. Enter your query or research prompt and click the Submit button.

NotebookLM will initiate a search for relevant sources that encompass a variety of platforms, including YouTube, Pinterest, and other social media channels. Please be patient; the duration of this search depends on the complexity of your query. After the search concludes, manually evaluate the proposed sources for relevancy and select those that align with your research needs. Given the evolving nature of the Discover Sources feature, it may not always perfectly interpret your intent, so careful review is advised.
Once you’ve made your selections, click on the Import button to incorporate your chosen sources.

If you’d like to add personal materials such as PDFs, text documents, or audio files, navigate to the Sources section and click on the Add button. From there, you may select your desired files using the media picker.

Making the Most of Your Imported Sources
With your sources neatly organized, click on the Chat section, input your query, and press the Send button to receive insightful responses.

Beyond basic responses, NotebookLM offers advanced features that enhance your exploration of the imported sources. For example, you can create mind maps or generate audio overviews of your research. Simply scroll down from the initial response until you reach these additional options.

To craft a mind map from your information, click on the Mind map option. NotebookLM will proceed to generate a visual map that encapsulates your findings. To view the generated mind map, head to the Studio section and select View Mind Map.

As for generating an audio overview, a dedicated guide is available that outlines the process comprehensively.
Despite its robust functionalities, Google’s NotebookLM has not received the same level of recognition as popular AI assistants like ChatGPT or Gemini. This variance stems from NotebookLM’s specialized focus on research and writing, distinguishing it from other tools. Even though NotebookLM offers powerful utilities, integrating it with additional AI resources can significantly amplify your productivity.
