Drop a book. Get an ebook and an audiobook.

One manuscript in — a clean EPUB and a fully narrated audiobook out. Everything runs free, right here in your browser (Chrome or Edge). Nothing is uploaded.

Read this first — it matters

We convert exactly what you send, word for word. Follow these five things and your book comes out clean. Skip them and it may not.

  1. Send a Word file (.docx). It keeps your punctuation and formatting best. EPUB, PDF, Markdown and TXT also work.
  2. Start every chapter on its own line — “Chapter One”, “Prologue”, “Part Two”. That is how we find your chapters.
  3. One blank line between paragraphs. Nothing fancier. That is how we tell them apart.
  4. Type real punctuation — em dashes (—), curly quotes, commas. We keep every one exactly as written.
  5. One file = one whole book. Not one chapter. Covers and images are added separately.

You will review every chapter before anything goes live — but the cleaner the file, the less there is to fix.
