Google Rebrands NotebookLM as Gemini Notebook, Adds Per-Notebook 'Secure Cloud Computer' for Code and Data Analysis

Google has renamed its popular research assistant NotebookLM to Gemini Notebook, keeping the standalone app intact while tying it more tightly to the wider Gemini ecosystem and rolling out a new per-notebook cloud execution environment.
