  • On Sharing, as of May 9, 2025, Google NotebookLM Help notes that “NotebookLM notebooks can be shared by clicking the Share icon, granting Viewer or Editor access via email, but 'personal Gmail accounts are limited to 50 individual users' and 'cannot share with Google Groups.’ Depending on 'licensing, institutional settings and user acccess," Google enterprise or EDU account holders can share with an unlimited number of individual users and Google Groups within the same organization.’  Learn more as this evolves from Reddit's notebooklm community. 

  • On privacy, as of May 9, 2025, Google notes that "NotebookLM does not use your personal data, including your source uploads, queries, and the responses from the model for training."

  • Bot vs Agents. NotebookLM is currently a customizable Google bot that queries Gemini, but it is not "agentic."  Agents involve advanced integrations with external sources, and have a higher degree of autonomy.
