Google is linking its NotebookLM research tool directly to the Gemini chatbot. This integration lets users select specific notebooks as context for their Gemini queries, effectively expanding the chatbot's knowledge base beyond its initial training data and standard web results. While NotebookLM already includes a built-in chat function powered by a Gemini model, it remains quite limited—it doesn't even save chat histories. The new feature addresses this by allowing users to leverage multiple notebooks simultaneously within the main Gemini interface. It also supports integration with "Gems," the personalized versions of the chatbot. The rollout appears to be gradual, starting with browser users, though app support will likely follow soon.
