NotebookLM becomes Gemini Notebook

Sources: Google blog, HN discussion
Summary: Google renamed NotebookLM to Gemini Notebook on 2026-07-16. It stays a standalone research product but gains deeper Gemini integration: notebooks are creatable inside the Gemini app with cross-app syncing, a code-execution feature for data analysis is rolling out to Pro users, and notebooks are planned for AI Mode in Search. Google cites more than 30 million users and 600,000 organizations.
Why it matters: The rename folds a widely used grounded-research tool into the Gemini product line and adds in-notebook code execution.
