2025-11-17
Summary
Google's NotebookLM has introduced a "Deep Research" mode, allowing users to scan hundreds of websites to create structured, annotated reports. The tool now supports more file types, including Google Sheets, PDFs, and images, and offers a chat history feature for continued or deleted conversations.
Why This Matters
These updates make NotebookLM a more robust tool for professionals needing in-depth research and data extraction capabilities. By supporting various file types and offering enhanced research modes, NotebookLM aims to streamline workflows and improve productivity. However, like other AI tools, it still faces challenges with accuracy and potential copyright issues.
How You Can Use This Info
Professionals can leverage NotebookLM to efficiently gather and analyze large amounts of information across different file formats, which can save time and enhance decision-making processes. The new chat history feature allows for more flexible collaboration and project management. However, it's important to verify the accuracy of AI-generated reports and remain mindful of copyright considerations when using generative AI tools.
