Google’s NotebookLM has taken a significant leap forward in its evolution as an AI-powered research and note-taking tool. Previously, users were required to manually add files and links to populate their notebooks. However, with the introduction of the new “Discover Sources” feature, Google is now enabling automated web search to find relevant sources for users.
This AI-driven feature aims to enhance the research experience by helping users quickly access curated materials on various topics. It simplifies knowledge acquisition, reduces the effort required to gather useful resources, and improves the way people interact with digital content.
This update, which is rolling out to both free and paid NotebookLM users, is just the beginning of Google’s vision for a more intelligent and self-sufficient AI assistant. The company has hinted at more advanced features leveraging the power of Gemini AI, Google’s latest AI model, to make research and note-taking even more seamless.
Let’s take a deep dive into this new feature, its potential implications, and how it enhances the overall user experience.
How the “Discover Sources” Feature Works
The Discover Sources feature is located in the Sources pane of NotebookLM. A new “Discover” button, represented by a magnifying glass with sparkles, appears next to the existing “Add” button. Clicking on this button opens a text box prompting the user to enter a topic or question they want to explore.
Once a query is submitted, NotebookLM searches the web and retrieves a curated collection of up to 10 relevant sources. Each recommended link comes with an annotated summary, which highlights why the source is useful for the given topic.
Users can:
- Add all sources to their NotebookLM workspace with a single click.
- Uncheck specific sources to select only the most relevant ones.
- Use the sources in various NotebookLM features, including FAQs, Q&A sections, and Audio Overviews.
This update significantly enhances NotebookLM’s role as a learning assistant, making it easier for users to quickly grasp new concepts and gather essential reading material on various topics.

Google’s Vision for AI-Powered Research
According to Google, Discover Sources is just the first of many features planned for NotebookLM that will integrate Gemini AI for more advanced research capabilities. The company has suggested that future updates will further refine how AI interacts with research data, making it smarter in identifying relevant information and providing contextual insights.
In addition to manual topic searches, Google has introduced an “I’m Feeling Curious” button. This feature randomly generates sources on a topic and allows users to explore different subjects without entering a specific query. It’s an innovative way for users to see the source discovery capabilities of NotebookLM in action.
