NotebookLM is pretty powerful on its own, but it’s rarely used in isolation. We all “pair” it with our other tools in one way or another, whether a browser for source retrieval, a notes app for capturing knowledge, or a chatbot for quick understanding. One of the things that makes NotebookLM so compatible with browser-based work specifically is the extensions. I honestly don’t know what I’d do without them because I already live in my browser – it’s where all my NotebookLM sources come from.
