Labels — organize your sources with NotebookLM's built-in labels, right from the extension. Unlike folders and tags (which stay private to this device), labels sync with your notebook, so anyone you share it with sees them too.

- Add several labels to any source, and filter your sources by one or more of them

- Color-coded label chips make groups easy to spot at a glance

- Let AI label your sources for you — tag everything, fill in just the unlabeled ones, or regenerate from scratch

- A dedicated Labels view to rename and reorganize your labels

- Built-in "Folders vs Labels" explainer so it's always clear what syncs and what stays on your device

Refresh out-of-date sources across many notebooks at once. Pick notebooks from your library and the extension checks every source for changes, then re-syncs the stale ones in a single run.

- See how many sources need updating in each notebook before you start

- Live progress as it checks and refreshes, with a heads-up when there's a lot to get through

- A clear summary at the end: how many were updated, still processing, or failed
