Google just announced one of the biggest NotebookLM updates I've seen since Audio Overviews launched, and it's clear the product is evolving from a smart research assistant to a tool with the ability to generate a much wider range of downloadable outputs.I've been using NotebookLM regularly for everything from article research to keeping my family organized and exploring ideas. What I love most about it is that it stays grounded in the materials you provide, reducing the hallucination problem that can plague traditional chatbots.Google says NotebookLM is now powered by Gemini 3.5 and a new system called Antigravity, which the company says improves accuracy, reliability and visibility into how the AI reaches its conclusions. Now, with a host of new capabilities, including code execution and web research for a more thorough and responsive AI tool. After reading through the announcement, three features stand out as the ones I'm most eager to try.1. NotebookLM can now run code This is the feature that immediately caught my attention. Google says every notebook will now be equipped with a secure cloud computer that allows NotebookLM to write and run code on your behalf. The company says this will help users perform deeper research, more advanced analysis and better understand the information inside their notebooks.That's a significant shift because until now, NotebookLM has largely focused on helping users understand and organize information. Running code moves it into a completely different category. Imagine uploading survey data, research reports or spreadsheets and then asking NotebookLM to analyze trends, compare datasets or generate visualizations without leaving the platform.As someone who spends a lot of time digging through reports and studies for AI stories, this is the feature I'm most curious to test in real-world scenarios.2. It can now create presenation decks, spreadsheets and reports
