EPUB to Markdown

Convert EPUB books into an AI-ready Markdown library with a first-read META.md navigation index, per-chapter Markdown files, and extracted images. Use when the user wants to turn a .epub into Markdown for reading, summarization, analysis, retrieval, or downstream text processing, especially when the book should be explored chapter-by-chapter without loading the entire text at once.

EPUB to Markdown Conversion

Convert an EPUB into a structured Markdown workspace using the bundled script.

Run

uv run scripts/convert.py <path/to/book.epub> [output_dir]

• Omit output_dir to write beside the EPUB as {epub_stem}/.
• If output_dir already exists, the script stops instead of deleting it.
• Pass --overwrite only when the user explicitly wants to replace an existing generated directory.
• Dependencies are declared inline in the script, so uv run installs them automatically on first use.

Output

{output_dir}/
├── META.md
├── images/
└── chapters/
    ├── 001_{slug}.md
    ├── 002_{slug}.md
    └── ...

• Read META.md first. It contains book metadata, total chapter and word counts, and a chapter index pointing at the generated files.
• Read files in chapters/ only when the user asks about specific content.

Reply Format

After a successful conversion, report:

✅ Conversion complete

Title   : {title}
Authors : {authors}
Chapters: {total_chapters}
Words   : {total_words}
Output  : {output_dir}/

If chapter titles look wrong, the TOC is sparse, or the user needs edge-case behavior details, read references/reference.md.
