NotebookLM Gains Powerful Chat History Feature
Mobile app users of NotebookLM are now benefiting from a crucial feature โ€“ chat history support. This functionality, initially unveiled by Google alongside a suite of AI chatbot enhancements in October, addresses a significant limitation of the tool. Users can now engage in a chat within NotebookLM, conclude the session, and effortlessly pick up their conversation again at a later time.

A Game-Changer for Research
NotebookLM is specifically designed as a research and study tool, helping users to effectively aggregate data and delve deeper into subjects of interest. A core element of this tool is the ability to initiate a chat within NotebookLM, close it, and seamlessly resume the conversation at a later time. This allows users to maintain context throughout their research process.

Breaking the Session Barrier
Previously, NotebookLM notebooks were fundamentally limited; each session would erase the context of previous conversations upon termination. This contrasted sharply with Gemini, which retains both Gemini and chat history, ensuring a continuous and uninterrupted research experience.

Seamless Continuity for Users
The newly added chat history support mirrors the functionality offered by Gemini, providing a much smoother and more intuitive workflow. Users can now build upon previous discussions, refining their understanding and analysis without the need to re-establish context repeatedly.
