Let Muse read it all
It comes back with your cast, your places, the words you invented — and the passage it found each one in.
Muse takes your notes and onboards the world around your manuscript.

Read aloud, following the page
Your manuscript,
read out loud.
Free, and local. The voice lives on your machine — no account, no connection, nothing counted by the word. And it says the names you invented the way you taught it, because it reads them from your glossary.
An editor's read,
whenever you want one.
Chapter Check knows the difference between a typo and your dialect. Manuscript Lens reads the whole book and finds the thread you dropped in chapter three.

The export view
EPUB
A real ebook, not a renamed zip.
- EPUB 3.3 to the W3C spec, with Accessibility 1.1 metadata and alt text on every image.
- The bundled W3C EPUBCheck runs on demand; a structural validator runs on every single export.
- Hybrid navigation — a modern nav document and a legacy NCX, so old Kindle and ADE ingestion still read it.
- Your ISBN is validated and bound as the package identity; without one, a unique ID is minted for you.
- Title, author, publisher, rights, language and contributors — with proper editor, translator and cover-designer roles.
- Reflowable and self-contained: the reader picks the font, and nothing in the book reaches out to the internet.
Print Edition
An interior a printer will take.
- Seven real trim sizes, from 5″ × 8″ up to 8.5″ × 11″ — the ones KDP, IngramSpark and Lulu actually print.
- Mirrored margins with a gutter that grows with the page count, exactly as the printers publish it.
- Chapters open on a right-hand page, with a blank verso inserted when the spread needs one.
- Running heads that know which side of the spine they are on, and folios where you want them.
- 0.125″ bleed and trim marks when artwork runs off the page.
- EB Garamond is bundled and always embeds; choose a system font and its licence is checked before a single byte is used.
- PDF/X-1a:2001 output intent, so a press can accept the file without a conversation.
Four manuscript styles come set up and ready — submission format for agents, a reading copy for beta readers, a wide-margin workshop copy, and a clean screen copy.
