- Saves which sources are ticked so you can switch context quickly.

- Deleting sources cannot be undone; download or archive first.
- Existing views stay available if Pro ends.

## Frequently asked questions

### Do I need Pro for the source tools?

Not for the basics. Free: Search, filter, bulk actions with 5 items per batch, and 2 saved views per notebook (5 overall). Pro: More saved views and no batch limit.

### Why save source selections?

NotebookLM answers only from ticked sources. A saved view restores a set, such as "only primary sources", without re-ticking each one.
