What a professional formatter quotes for one book — plus two to three weeks of your launch window.
DIY in Word
Hours fighting margins, then KDP bounces your paperback over gutter width. Launch delayed by days.
Rewritten?
AI formatting tools that polish your prose. Your voice, quietly deleted in a hundred small places.
You spent months — maybe years — writing your book. The last thing you need is a formatting headache, a rejected KDP upload, or an AI tool quietly rewording your sentences. We built Stetbook so you can skip all of it. One upload. One payment. One less thing to worry about.
Three steps. Sixty seconds. Done.
01
Drop your manuscript in
Your .docx, as-is. The free pre-press audit runs in seconds — no credit card, no tricks.
02
Read your audit
Every mechanical fix listed: margins, gutters, spacing, typography. Creative edits: zero. Verified word-for-word.
03
Unlock your files
Print-ready PDF in your trim size, Kindle-ready EPUB, and a cover spec sheet. One payment, yours forever.
The Zero-Rewrite Promise
Stet: the proofreader's mark that means let the author's words stand.
It's also our contract with you. Every mechanical fix is listed in your audit. Every job ships with a character-by-character check: the only changes allowed are spacing and punctuation glyphs — straight quotes to curly, for example — and each one is listed in your audit.
✓ Prose match: 100%. Glyph changes itemised in every audit.

Everything your book needs to ship.

Questions authors actually ask.
Will Stetbook change my words?+
No. The engine applies mechanical formatting only — margins, gutters, spacing, typography. Every job ships with a character-by-character comparison against your original. Spacing and punctuation glyphs are the only changes, and your audit lists every one.
My book is image-heavy (activity or puzzle book). Will it work?+
Version 1 is optimized for text-driven books: novels, memoirs, and nonfiction. Image-heavy layouts are on the v2 roadmap. The free audit will always tell you honestly what we can and can't do.
Found a typo after formatting — do I pay again?+
No. Fix your .docx and upload again. Re-uploads of the same book are free for 45 days, so you can correct, tweak and re-export every file before and after launch.
Can I choose how my book looks?+
Version 1 ships one classic publisher style, with more on the way. Your title page, copyright page and table of contents are built automatically. We believe in doing one thing perfectly rather than ten things poorly.
What sizes and files do you support?+
Paperback trims: 5 x 8, 5.25 x 8, 5.5 x 8.5, 6 x 9 (KDP default), 8.5 x 11. Upload a Word .docx (from Google Docs: File → Download → Microsoft Word). Hardcover interiors are coming Q1 2027. Your ebook arrives as a Kindle-ready EPUB.
Can I edit the files after I download them?+
Yes. The PDF and EPUB are yours to open in any compatible software. We recommend using our files as your starting point — they're built to pass submission as-is.
Why not use a free tool like Kindle Create or Reedsy?+
Free tools are great if you have the time to learn them and set every margin yourself. Stetbook is for authors who want it done correctly the first time: upload your .docx, get an audit of every fix, and receive files with KDP gutters calculated from your final page count and a character-level check that your words are untouched. No templates to learn, no settings to guess.
Which platforms do the files work on?+
The print PDF follows Amazon KDP paperback specifications and is built to be accepted by print-on-demand platforms generally. The EPUB is built for Kindle publishing.
How long does it take?+
About 60 seconds from upload to audit. Unlocking your files takes one payment.
What if I don't like the output?+
Email us within 14 days and we'll refund you in full. No questions asked. If our file ever fails KDP submission, we'll fix it or refund you — that's the promise.
Make your book look like it came from a real publishing house.
The audit is free and takes 60 seconds. The rest is one payment.
