Gemini adds notebooks, NotebookLM sync

Google is pushing Gemini from a chat interface toward a persistent project workspace, and that is the right direction for heavier research and study workflows. The NotebookLM bridge is the real differentiator, but the rollout still feels deliberately staged to premium users first.

• –Notebooks let users keep related conversations, documents, and PDFs together instead of scattering context across separate chats.
• –Gemini can use notebook sources alongside web search, which makes the feature closer to lightweight RAG than a plain chat folder.
• –Sync with NotebookLM means users can start in one app and continue in the other without re-uploading sources or rebuilding context.
• –The initial paid-web rollout makes this more of a retention feature for Ultra, Pro, and Plus than a mass-market relaunch.
• –Exclusions for under-18, Workspace, and Education accounts narrow the immediate audience even further.
