How to Use Kindle Books in NotebookLM

This guide shows how to create personal reading-note text from a Kindle Cloud Reader book with BookHalo, then use that text in Google NotebookLM for summaries, questions, reading notes, and audio overviews.

Short version: use BookHalo to create full_text.txt, then use that text file in NotebookLM for your own reading notes. Use the PDF for visual reference and the TXT file as the AI-friendly source.

What you need

BookHalo is a Chrome extension. It works in the browser-based Kindle reader, not in the Kindle desktop or mobile app.

1. Install BookHalo from Chrome Web Store

Install BookHalo from the Chrome Web Store. After installation, pin BookHalo to your Chrome toolbar so it is easy to start while your Kindle book is open.

2. Open your book in Kindle Cloud Reader

Open read.amazon.com or your regional Kindle Cloud Reader / Kindle for Web domain, then open the book you want to use in NotebookLM.

Important: use the browser reader. Kindle samples and preview-only pages are not supported.

3. Create TXT and PDF with BookHalo

With the book open, click the BookHalo icon and start OCR. BookHalo turns pages, captures visible pages, runs OCR, and downloads a ZIP file when processing is complete.

The ZIP usually contains:

4. Use full_text.txt in NotebookLM

Create a new NotebookLM notebook, unzip the BookHalo result, and use full_text.txt as a personal reading-note source. Name the notebook with the book title and author so it is easy to find later.

5. Ask better first questions

Instead of asking for a generic summary, ask for a specific output shape.

Why TXT is usually better than PDF for NotebookLM

NotebookLM can ingest PDFs, but for OCR output the plain text file is usually the better first source.

Regional Kindle stores

BookHalo supports multiple Kindle Cloud Reader / Kindle for Web domains, but Kindle availability can differ by region and account. If your local Kindle for Web domain behaves differently, try the free tier first and contact us with the domain and book type.

Best-fit books

BookHalo is available on the Chrome Web Store. You can create TXT/PDF files from books you can access in Kindle Cloud Reader for personal reading notes, study, and research.
