Google's April 2026 Gemini Drop introduces Notebooks that sync bidirectionally with NotebookLM — any source added in either app appears in both, enabling workflows like starting research in Gemini and generating Video Overviews or Infographics in NotebookLM. The native macOS app launched globally for macOS 15+. New chat import tools let users migrate personal context, preferences, and full chat history from competing AI apps directly into Gemini. For builders evaluating AI assistants, the NotebookLM integration creates a research-to-analysis pipeline no competitor currently matches.
