TL;DR
- NotebookLM 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.
