In the ongoing human effort to make sense of fragmented knowledge, Google has meaningfully expanded what its NotebookLM research tool can do — rebuilding its reasoning engine around Gemini 3.5 and granting it the ability to write and execute code within a researcher's own workspace. The upgrade arrives not as a novelty but as a response to how inquiry actually unfolds: messily, incrementally, across scattered sources and half-formed questions. What Google is offering is less a smarter chatbot and more a research environment that attempts to stay with the thinker through the entire arc of disco
