Ebook Text Extractor
Overview
Extract plain text from EPUB, MOBI, and PDF files using Python scripts. No LLM calls - pure text extraction.
Supported Formats
| Format | Tool Used | Notes |
|--------|-----------|-------|
| EPUB | ebooklib + BeautifulSoup | Direct parsing, preserves structure |
| MOBI | Calibre ebook-convert | Converts to EPUB first, then extracts |
| PDF | PyMuPDF (fitz) | Fast, handles most PDFs well |
