Which AIWriteBook file goes where

The formatter exports four files in one run. Each one has a clear destination.

  • EPUBUpload to Draft2Digital as a finished ebook when you want your own layout kept exactly. It is checked with EPUBCheck before you download it.
  • DOCXUpload to Draft2Digital instead when you want D2D's converter to build the ebook and add its automated end matter.
  • Front coverUpload as the ebook cover. D2D can build a print wrap cover from it.
  • Wrap coverUse for KDP Print or IngramSpark, or upload to D2D Print after matching D2D's cover template.
  • Print PDFUpload to KDP Print or IngramSpark directly. It is built for both.

Our step-by-step guide on how to publish on Draft2Digital walks through the upload, metadata, store selection and D2D Print setup with these exact files. If you plan to go direct to some stores instead, publishing on IngramSpark and KDP vs IngramSpark cover the print side.

The overlap: formatting

Both tools turn a manuscript into book files. They start from different places.

Draft2Digital's converter takes a Word file, or RTF, ODT or TXT, and builds an ebook and a print edition from it, with automated end matter such as an also-by list and a teaser for your next book. You can download the converted files for free, even if you publish elsewhere. It also accepts a finished EPUB for ebooks.

AIWriteBook's book formatter works on the book you wrote or imported into the editor: five interior themes, 12 embedded fonts, nine trim sizes, front and back matter, and an exact proof, then a print PDF, an EPUB, a DOCX and a wrap cover. The formatter costs 200 credits once per book.

Questions writers ask

Is AIWriteBook a Draft2Digital alternative?
Not for wide distribution. Draft2Digital delivers your book to stores and libraries. AIWriteBook writes and formats the book, publishes to KDP through its extension, to NanoReads and to your author page, and exports the EPUB, DOCX, print PDF and wrap cover you upload to Draft2Digital or anywhere else.
Can I upload an AIWriteBook EPUB to Draft2Digital?
Yes. Draft2Digital accepts an existing EPUB for ebook distribution, and AIWriteBook's EPUB is checked with EPUBCheck. Upload the DOCX instead if you want D2D's converter and automated end matter.
Does Draft2Digital accept books written with AI?
Draft2Digital accepts AI-assisted books, but not content generated entirely by AI without extensive human editing. In AIWriteBook you stay the author: you guide the outline, and every edit is shown as a change you accept, reject or rewrite.
Does AIWriteBook distribute to Apple Books, Kobo or Barnes & Noble?
You upload to those stores yourself, or through Draft2Digital, using AIWriteBook's EPUB and cover. AIWriteBook publishes directly to KDP through the Publishing Assistant, to NanoReads and to your author page.
Do I still need Draft2Digital's formatting if I use AIWriteBook?
No. AIWriteBook exports a finished EPUB and print PDF. Some authors still upload the DOCX to Draft2Digital for its automated also-by list and teaser.
What does Draft2Digital cost?
A $20 one-time activation fee, about 10% of the retail price on each ebook sale, and a $12 yearly maintenance fee for accounts earning under $100 a year.
