BookKraft AI
Scores an ebook manuscript against KDP, Apple Books and Kobo rules before you upload.
BookKraft AI scans an EPUB or Word manuscript for the structural and metadata problems that get books rejected — a table of contents not linked to a chapter, a cover a few pixels under Apple Books' minimum height, a title that doesn't match between cover and metadata — and gives a readiness score plus per-platform status for Amazon KDP, Apple Books, Kobo and IngramSpark. It also converts a .docx or .txt manuscript straight to EPUB 3.0 with chapter detection, no Calibre or Sigil needed. Five tools are free with no signup; pricing beyond that is one-time credits that don't expire, not a subscription.
