QUESTIONS · SOURCES AND LIMITS

Can NotebookLM update sources automatically?

ProVerified · NotebookLM / Gemini Notebook·Markdown

Short answer

Mostly no. A web or file source is a copy taken when you added it; only Google Docs and Slides sources can be re-synced by hand. To keep a notebook current, NotebookLM Ultra Exporter Pro can check an RSS feed, website, playlist or AI chat history on a schedule and import what is new.

What to know

  • Scheduled checks run while Chrome is open and you are signed in.
  • Already imported items are skipped.
  • Each new item is a new source, so watch the source limit.

Google changes these menus often. The item's own menu in your notebook shows what is built in today.

Free or Pro?

Requires Ultra Exporter Pro (annual or one-time). Pro covers the extension only; it does not include a Google subscription or raise NotebookLM's own limits. Current prices are on the pricing page.

Frequently asked questions

Does a changed web page update its source?
