At the end of 2024, Google was one of the first companies to start offering a Deep Research tool through its AI chatbot. Now, nearly a full year later, the company is bringing that same capability to NotebookLM. Like its Gemini counterpart, the tool allows you to task the app with generating an extensive report on a single topic. When you queue a Deep Research task, NotebookLM will browse hundreds of websites on your behalf before it starts writing up its findings.
The entire process can take a few minutes, but at the end you'll have a multi-page report to read. As the model works in the background, you can instruct it to seek out specific online sources. NotebookLM will also recommend articles, papers and websites that might be relevant to your query. Once its findings are ready, you can use any of NotebookLM's capabilities to generate insights on the content.
With today's update, Google is also adding to the variety of sources NotebookLM can access. Now the app can pull data from Google Sheets, Microsoft Word documents and PDFs you've uploaded to Google Drive. It's now also possible to add Google Drive files just by copying over the URL. Google says all of today's enhancements should roll out to users within a week. The timing of the update is fortuitous given the company recently gave NotebookLM the capability to generate flashcards and quizzes.
