Jordan Wilson details seven major updates to Gemini Notebook, formerly NotebookLM. The tool is now agentic by default, featuring a secure cloud computer for code execution, automatic Google Drive syncing, and integration with Gemini and Search. A key change is the ability to generate multiple outputs from a single prompt, including mind maps, infographics, quizzes, and editable Excel workbooks. The host demonstrates a complex prompt that produces a full executive decision package, showcasing the tool's chain-of-thought reasoning and cost analysis capabilities. Gemini Notebook now runs on Gemini 3.5 and includes an anti-gravity agentic search engine. The new Studio pane allows for multi-modal asset creation, while the agentic harness enables browser control and external source import with user approval. The episode emphasizes the shift from strict grounding to a more flexible web research capability, which reduces hallucinations while allowing for broader queries. Overall, these updates position Gemini Notebook as a versatile agentic co-worker that can significantly reduce manual work and generate professional-grade artifacts.
