Google’s latest update to NotebookLM, its AI-powered research workspace, introduces a major enhancement called Deep Research, along with support for a wider range of file types commonly used across technical teams. These improvements aim to help professionals gather insights faster, work more efficiently, and centralize research workflows without bouncing between multiple tools or platforms.
Researching emerging threats, evaluating new technologies, and reviewing industry best practices often requires combing through large quantities of trusted information. Deep Research is designed to automate much of this effort by functioning as a dedicated AI research assistant.
With a single prompt, Deep Research can:
- Build a step-by-step research plan
- Browse and analyze hundreds of websites
- Identify high-quality, relevant sources
- Refine its search as it learns what matters
- Produce a clear, organized report grounded in the sources it found
Unlike many AI tools that generate quick or simplified summaries, Deep Research focuses on depth, accuracy, and clarity, giving users a more complete understanding of the topic they’re exploring.
Smooth Integration Into the NotebookLM Workflow
You can add Deep Research directly into your existing notebook and continue building your collection of information without breaking your workflow. The report and all of its references can be saved alongside your other materials, making it easy to keep everything in one place.
As you continue working, you can bring in additional documents, links, or notes, and NotebookLM will incorporate them into your growing knowledge base. The platform also offers audio and video overview tools that can turn dense or complex material into clear summaries, making it easier to review information quickly.
This creates a streamlined, centralized workspace where Deep Research’s findings and your own content work together naturally without the need for multiple lists or complicated steps.
To make the platform more flexible, now supported are several common file types, making it easier to bring all of your materials into one place. NotebookLM now supports:
- Google Sheets – Useful for examining structured data, generating summaries, or pulling statistical insights from security logs, budgets, or asset inventories.
- Drive File URLs – Paste links directly from Google Drive just as you would a webpage or YouTube video, with support for importing multiple URLs at once.
- Images – Upload photos of whiteboard sessions, handwritten notes, or printed materials for immediate analysis.
- PDFs from Google Drive – Add research papers, vendor reports, compliance documents, or ebooks without needing to download and re-upload.
- Microsoft Word (.docx) – Analyze policies, technical notes, client drafts, or internal documentation with direct Word file support.
A Useful Upgrade for IT and Cybersecurity Teams
As organizations continue to navigate complex threats, evolving technologies, and expanding data workloads, tools that simplify research and centralize information become increasingly valuable. Google’s latest updates to NotebookLM — combining Deep Research with broader file support — offer a meaningful step toward more efficient, informed decision-making in technical environments.
