Google is pairing up two of its research products: NotebookLM and Gemini’s agentic AI tool Deep Research. On Thursday, the company announced that all users will have access to Deep Research in NotebookLM within a week.
Now, NotebookLM users will be able to direct a question to Deep Research and choose between two research styles: fast or deep. The fast research style will “rapidly” look for information, while the deep style will do “in-depth analysis to find high-quality sources,” Google says. Users will get a research plan before the research begins using either style.
If you choose to go deep with Deep Research, you’ll be able to add more sources as the report generates in the background. Google’s blog says this will help “you assemble a rich knowledge base on any topic without leaving your workflow.” The final report on the topic will include citations to relevant articles, websites, or papers, all of which you can pop into your notebook.
In addition to Deep Research, NotebookLM is expanding to work with several new file types. You can now link Google Sheets and ask for statistics based on the structured data, or you can add Drive files like PDFs via URL link instead of uploading them directly to NotebookLM. Google will now also let users add Microsoft Word files in .docx format to NotebookLM.
