To study a book in NotebookLM, use the book import in NotebookLM Ultra Exporter Pro. It parses the EPUB, previews it by chapter, and imports each selected chapter as its own text source, so citations point to a chapter rather than the whole book.

## Quick facts

| Item | Detail |
| --- | --- |
| Where | Import center, book chapters method |
| Plan | Pro |
| Allowance | Pro only. No extension daily quota; individual tools still have task caps. |
| Data flow | The material you select is sent to Google NotebookLM. Capture reads the source site from your browser. |

## 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. Connect Pro: open the extension's account panel and sign in with the Google account you bought Pro with.
3. Open the import center and choose book chapters.
4. Select the EPUB file; your original file is unchanged.
5. Tick the chapters to import, confirm the target notebook and submit.

## Limits to know

- The e-book must be one the extension can parse; protected files cannot be read.
- Each chapter is one source and counts toward the source limit.
- Import only books you have the right to use this way.
- 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 an EPUB book into NotebookLM by chapter?

No. This import method is part of Ultra Exporter Pro. The basic methods (links, pasted text, files, tabs, the current page, RSS and YouTube) are free within 20 imports per day.

### Why import by chapter instead of one file?

Chapter sources give more precise citations and let you select only the chapters relevant to a question.

### 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.
