How TextMuncher ExtractsText from Any Ebook
Not file conversion. Not DRM removal. TextMuncher automates the screenshot-and-OCR workflow you'd do manually — in a fraction of the time.
Local-First Processing
Works with Kindle Cloud Reader
No Desktop Software
The 5-Step Process, Explained
Before capturing in Kindle Cloud Reader, switch to a single-column layout, turn off reading-progress markers, and dismiss pop-up controls so only the book text appears in each screenshot.
1. Install the Chrome Extension
No account required — just click install and it's ready. Works immediately.
2. Open Your Book in Kindle Cloud Reader
Go to Kindle Cloud Reader (read.amazon.com) and open the book you want to extract. That is where TextMuncher's automated capture runs.
3. TextMuncher Captures Pages Hands-Free
Click the TextMuncher icon and hit start. The extension automatically turns pages and captures screenshots hands-free. Long capture runs can stop early and may need restarting.
4. OCR Converts Screenshots to Text
TextMuncher's parallel OCR engine processes captured screenshots with four workers for higher throughput. Speed mode runs OCR locally in your browser by default; optional Pro Quality mode uses a cloud second pass.
5. Copy or Download Your Text
Review, edit, copy to clipboard or download. Paste into ChatGPT, Notion, Google Docs, or any tool.
Why Screenshots Instead of File Conversion?
No DRM Removal
TextMuncher doesn't touch DRM or encrypted files. It reads what's on your screen, the same as you would manually.
OCR for Captured Pages
TextMuncher reads what is on screen, not the ebook file. Automated page-turning is built for Kindle Cloud Reader. For other readers, capture the pages yourself and upload them for OCR.
Parallel OCR Built for Book Text
Four OCR workers process screenshots in parallel. Standard prose typically extracts cleanly. Complex layouts may need correction.
Under the Hood
Parallel OCR Engine
4 Tesseract.js web workers run simultaneously, processing screenshots ~75% faster than sequential.
Local Processing by Default
Speed mode runs OCR in your browser and sends nothing to external servers. Optional Pro Quality mode sends only hard-to-read pages for a cloud second pass.
Smart Page Detection
Detects the ebook reader, waits for full page load before capturing each screenshot.
EPUB Direct Extraction
For EPUB files, TextMuncher uses JSZip to read the actual text data — the exact text, character-for-character, no OCR needed.
What the Demo Shows
The 55-second demo on the homepage walks through one complete capture, start to finish. It opens on a Kindle Cloud Reader library, where a book is picked and opened. The TextMuncher side panel detects the open book and gets ready to capture. A page count is set, capture starts, and the panel turns pages and collects screenshots on its own while the counter climbs — a chapter or a whole book runs unattended. The captured pages are downloaded as a ZIP, then dropped into the TextMuncher web app at textmuncher.com, where OCR runs in the browser and turns the screenshots into text. The output screen arrives just before the closing title card: the chapter as plain text with a character count, a Copy All button and a Download button, ready to paste into ChatGPT, Claude, or your notes. The footage is a screen recording of the shipping extension and web app; the captions and the closing title card were added in the edit.
Frequently Asked Questions
Why does TextMuncher use screenshots instead of converting the file?
Cloud ebook readers don't let you download the book file. TextMuncher works with what's available — the rendered page in your browser.
How accurate is the text extraction?
TextMuncher uses four parallel OCR workers tuned for standard book text. Standard prose typically extracts cleanly. Technical books with complex layouts, equations, or heavy formatting may need correction. For the numbers and how they were measured: the published OCR benchmark and its method.
Does my book data leave my computer?
In Speed mode — the default — no: OCR runs in your browser and your screenshots and text stay on your device. Quality mode, an optional Pro feature you switch on per extraction, sends the pages flagged as hard to read (the page image and its draft transcription) to a cloud OCR service to be re-read, then returned to you.
What ebook platforms does TextMuncher support?
Automated page turning and screenshot capture are built and validated for Kindle Cloud Reader (read.amazon.com). For any other reader, take screenshots of the pages yourself and upload them to textmuncher.com. Only the automated page turning is Kindle-specific.
Can I also upload my own screenshots or EPUB files?
Yes. The web app at textmuncher.com lets you upload screenshots for OCR or EPUB files for direct text extraction.
