Google is quietly preparing to launch a new feature in NotebookLM that addresses a long-standing user request: persistent chat conversation history. This upcoming capability, revealed through a newly spotted but still hidden label in the interface, suggests that chats will no longer be wiped at the end of each session. Previously, users would lose access to any dialogue with the system after closing NotebookLM, which limited ongoing research or collaboration workflows, especially for those in business and education who rely on cumulative note-taking or knowledge compilation.
While the exact implementation is not public, it appears that transcripts of prior chats will soon be visible directly in the main chat menu, making it possible to revisit previous queries and discussions each time the app is loaded. There's no official confirmation yet on how detailed or searchable this history will be, but saving the chat state aligns closely with features found in competing research assistants and knowledge management tools.
For Google, this change fits their broader strategy of expanding NotebookLM’s utility for professional and educational teams, as they continue to iterate on document sourcing, AI-generated overviews, and now, session continuity. The shift comes after a noticeable delay, likely reflecting both technical and privacy considerations. If the rollout follows previous feature launches, an announcement can be expected in the next couple of weeks, benefiting anyone who relies on NotebookLM for multi-session projects or collaborative research.
