Book Builder takes your locked message and produces a real, publishable manuscript — not a 12-page outline labelled "book". It opens as a three-mode Writing Room: Write, Design, Publish.
Write mode
- Distraction-free Focus Editor with autosave, session timer, word-goal ring
- Slash menu (/) for headings, scripture, callouts, images, citations
- Inline AI bubble — select a sentence, get a rewrite in your Voice DNA
- Command palette (Cmd-K) to jump chapters, modes, tools
- Find & Replace with live counter and Find Next/Previous
- Voice Drift detector flags chapters that stray from your saved Voice profile
- Find Sources — research 5–10 real citations (books, articles, sermons, scripture, web) grounded in the chapter's claims; accept or reject each one, and accepted citations roll into your bibliography on KDP export
Design mode
- Two-pane workspace: thin tab strip (Cover · Typography · Front/Back Matter · Images · KDP Polish), full canvas on the right
- Cover Studio with AI cover variants tuned to genre
- Typography: trim size, fonts, drop caps, chapter openers
- Front & Back Matter: title page, dedication, foreword, about-the-author, also-by
- Image Library for figures, author photo, scripture cards
- True facing-page Spread Preview (gutter shadow, single-page fallback under ~820px)
- KDP Polish pass: widow/orphan, page-break, blank-verso, headers/folios
Publish mode
- Shadow Read — AI critique flags weak chapters, drift, repetition, arc gaps
- Share Links — private read-only link for beta readers, no login
- Feedback Queue — capture comments inline, triage, mark resolved
- Endorsement Pack — personalised ask + blurb template + follow-up
- Audiobook — render chapters in your cloned ElevenLabs voice
- Launch Pack — 14-day email + social sequence, A+ content, keywords, ad angles
- KDP Submission Checklist — pre-flight checks + every Amazon KDP form field pre-filled (title, subtitle, description, keywords, categories, pricing) + cover asset bundle
- Launch Builder (
/book/$id/launch) — dedicated workspace that assembles the full 14-day launch pack into one place to review, edit, and export - Box-Sets (
/book/boxsets) — bundle multiple finished books into a series box-set with its own title, cover, description, and KDP submission flow
