NotebookLM now integrates Deep Research to automate complex searches and adds support for more file types you use every day. Can you imagine delegating the heavy lifting of search and keeping to build your notebook while the system fetches sources and an organized report? That's exactly what they present.
Deep Research: your research agent inside the notebook
Deep Research acts like a dedicated researcher: it takes your question, designs a search plan, and explores hundreds of websites, refining queries as it learns. In minutes it gives you an organized report, with citations and links, ready to add to your notebook.
What makes it different? First, the report isn't a separate PDF: you can import the report and its sources directly into your notebook and keep adding material while the agent runs in the background. Second, you can then use NotebookLM's features—like audio or video summaries—to transform those findings and understand them better.
