To turn a research session into a notebook, open the NotebookLM Ultra Exporter import center, choose browser tabs, tick the tabs you want and import them together. It reads tab addresses once, only when you click. Free imports 5 tabs per batch and 20 sources per day.

## Quick facts

| Where | Import center, browser tabs method |
| Plan | Free |

## Steps

1. Install [NotebookLM Ultra Exporter](https://chromewebstore.google.com/detail/notebooklm-ultra-exporter/afchokljnhhggkhedfbmkcmdagjmjchj) in desktop Chrome, then refresh any open NotebookLM (Gemini Notebook) tab.
2. Open the import center from the workspace or the in-page toolbar and choose the tabs method.
3. Grant permission to read tab addresses when asked.
4. Tick the tabs to import, confirm the target notebook and submit.

## Limits to know

- Browser-internal pages and NotebookLM pages are excluded.
- Free handles 5 items per batch; import a large window in several batches or use Pro.
- Google's own limits still apply: sources per notebook, file size and accepted file types are decided by NotebookLM, and Pro does not raise them.

## Frequently asked questions

### Is it free to import all open browser tabs into NotebookLM?

Yes. It is a basic import method. Free allows 20 successful source imports per local day and 5 items per batch; Pro removes both limits.

### Does the extension watch my tabs?

No. Tab addresses are read once, at the moment you choose this import method.

### What happens if a source is already in the notebook?

The import preview flags duplicates and items already in the target notebook, and you can skip them. If you import the same page again on purpose, NotebookLM creates a second copy.
