EPUB to Markdown
Drop an .epub and get the whole book as Markdown — chapters in true reading order, cleanly converted. It runs in your browser, so the file is never uploaded.

The whole book, in the right order
Under the hood an EPUB is a zip of XHTML files plus a manifest. This converter opens that package, reads the spine — the book's declared reading order — and converts each chapter through the same clean HTML-to-Markdown step used across these tools. The result is one Markdown document, chapters in sequence, with the book title on top.
Why Markdown is the format for long-document AI
Feeding a book to an AI means giving it plain, linear text it can move through — not a styled, zipped container. Markdown strips the packaging and keeps the structure, so the book is ready for summarizing, chapter-by-chapter retrieval, or a question-answering index, without the token overhead of the original markup.
Private and free
The book is processed entirely on your device. Copy the Markdown or download a .md file — your library stays yours.
