You return to a research notebook, ask the same question, and get a different answer. The documents behind it may have changed while you were away.

In Google's existing Gemini Notebook workflow on desktop, imported Drive files can stay connected to their originals. A colleague's edits can reach the notebook without another upload: Google says changes sync every few minutes and update when you open it.

A shared source can also disappear from the conversation. If its owner deletes the file or removes your access, Google says notebook chats stop referencing it.

For a project that keeps evolving, that connection is useful. For comparing yesterday's analysis with today's, the notebook name alone doesn't identify the evidence you used. Check the linked documents' revisions and availability before treating the changed answer as the AI changing its mind.
