It also supports 500 chat queries and 20 AI-generated audio summaries daily.

Priced at$20 per month, the subscription also includes access to Google's Gemini AI across Gmail, Docs, and 2TB of cloud storage.

Google has yet to reveal the number of users for NotebookLM but reports suggest millions of visits in recent months.
