Chapter Twelve

The manuscript opened on a wet street in November, and the city had not yet learned her name. She set the page down and read the first line again, slower this time — the one that had started everything.
Line Editor — a draft suggestion, ready for your eye.

Chapter Nine
She had not meant to keep the letter. It sat in the drawer for a year, the way small betrayals do, until the morning it didn't.

// The AI Studio

A writing staff, on call.

Five specialists powered by Claude. Share nothing, the synopsis, a single chapter, or the whole manuscript — and bring a reply straight into your draft. The author always leads; the staff only ever assists.

The Co-Writer

Drafts and continues chapters in your voice — a suggestion to accept, edit, or ignore.

The Developmental Editor

Structure, pacing, stakes, and character arcs — the shape of the whole book.

The Line Editor

Sentence-level polish and copyediting that respects your style.

The Publishing Coach

KDP strategy — categories, pricing, and a launch plan that fits your book.

The Blurb Writer

Back-cover blurbs, Amazon descriptions, and ad copy that sell without shouting.

// Why Inkbound
Built to feel like the inside cover of a beautifully made hardback — considered, intimate, and made to last. AI assists the writer; it never takes the pen.
— craft over hype, always.
// Design

Typeset like a real book.

Choose a template, set your trim, and watch the page compose itself — the way it'll actually print, not a rough approximation.

  • Six templates — Novel, Memoir, Non-fiction, Cookbook, Coffee table, Poetry
  • Eight KDP trim sizes, book typefaces, size & leading control
  • Chapter-opener styles, ornaments & drop caps
  • A live typeset page preview as you work
