BookKraft AI - AI-powered EPUB and Kindle formatting for indie authors
by•
BookKraft AI converts manuscripts into store-ready EPUB and Kindle files in minutes. It includes an EPUB validator that catches spacing and ID errors, a Kindle Format Fixer, and a cover dimension checker — all built for indie authors, no design skills needed.

I built BookKraft AI after formatting my own books manually and getting rejected by KDP for hidden EPUB errors. I wanted a tool that catches those issues before upload, not after. It started as a validator and grew into a full formatting suite.
