Kindle Cloud Reader OCR
BookHalo is a Chrome extension for OCR from Kindle Cloud Reader pages. It captures the pages you can view in the browser, runs OCR, and exports text plus a reference PDF.
What makes the workflow useful: the result is not just screenshots. The ZIP includes OCR-created text, usually as
full_text.txt, and a reference PDF.How it works
- Open your book in Kindle Cloud Reader or Kindle for Web.
- Start BookHalo from Chrome.
- BookHalo turns pages and captures visible page images.
- The captured pages are OCR processed.
- You download a ZIP containing OCR text and a reference PDF.
What you can do with the output
- Search through a personal reading-note text file.
- Use the text with NotebookLM, ChatGPT, Claude, or another AI tool if its terms allow it.
- Keep the PDF for visual reference and spot checks.
- Review dense books without manually copying page by page.
What BookHalo is not
BookHalo is not a DRM removal tool and does not replace buying or accessing a book through Kindle. It works from the rendered browser reader and is intended for personal reading notes and study support.
