TL;DRNotebookLM is getting a major upgrade with Gemini 3.5 and Antigravity, bringing improved accuracy, reliability, and greater visibility to how the AI reaches its answers.The tool can now do much more than research, including writing and running code, and generating reports, spreadsheets, presentations, charts, and other files directly from source material.You no longer need to start with a pile of documents. NotebookLM can help build a source library from an idea or a question while keeping you in control of which sources are included and cited.There aren’t many AI tools I rely on every single day, but NotebookLM is one of them. It has become my go-to tool whenever I need to sift through large amounts of information without losing track of where the facts came from. Now, Google’s latest update aims to make that experience even better.
