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

Usage

Unified extractor (auto-detects format):

python3 ~/.claude/skills/ebook-extractor/scripts/extract.py /path/to/book.epub
python3 ~/.claude/skills/ebook-extractor/scripts/extract.py /path/to/book.mobi
python3 ~/.claude/skills/ebook-extractor/scripts/extract.py /path/to/book.pdf

Output options:

# To stdout (default)
python3 scripts/extract.py book.epub

# To file
python3 scripts/extract.py book.epub -o output.txt
python3 scripts/extract.py book.epub > output.txt
