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.

## Frequently asked questions

### Does a changed web page update its source?

No. Remove the old source and add the page again to capture the new version.
