The Gemini app is rolling out notebooks that group chats and uploaded files into persistent workspaces, while tying those spaces more tightly to NotebookLM. Each notebook acts as a container where users can pin sources, continue threaded conversations, and return to previous prompts without rebuilding context.

NotebookLM integration now moves beyond simple source support inside Gemini. A notebook can be promoted into a NotebookLM project, carrying over documents and conversation history so that long‑form drafting, outlining, and citation management happen in one environment. Gemini remains the front door for quick queries and multimodal input, while NotebookLM handles structured reasoning over larger knowledge sets and generates more polished outputs.

The notebooks feature also reframes how the assistant treats memory and retrieval. Instead of relying only on transient chat history, Gemini can associate prompts with specific collections of files, which improves relevance and reduces repeated uploads. For users already working across Gemini and NotebookLM, the update turns what were separate tools into a more continuous workflow that spans capture, analysis, and final drafting.
