The Problem With Your Writing Stack

Authors end up juggling tools that never talk to each other.

Five tools for one book

A writing app, an AI chat, a grammar checker, a formatter and a cover tool, each with its own subscription.

AI bolted on

Most writing software adds an AI box that knows nothing about your characters or your style.

Formatting is its own project

Getting a clean print PDF and EPUB means learning another program.

Publishing is manual

Every KDP field, keyword and category is typed in by hand.

One Place for the Whole Book

Writing software that covers each stage and keeps your voice through all of them.

1.Write

Write it in your voice

Start from an idea or bring the draft you already have. Add a sample of your writing, shape the outline and characters, then write chapter by chapter. The AI proposes each chapter; you decide what stays.

  • Paste 6 to 10 paragraphs of your own writing and every chapter follows that style
  • Import a Word .docx of up to 200,000 words without a line of it rewritten
  • An outline, characters and chapters you can reorder, edit or rewrite
  • Choose the model for each chapter: Gemini, Claude or Grok
  • Standing instructions for the book, extra instructions for any chapter

2.Edit

Edit without losing yourself

Editing keeps your voice and leaves every decision to you. Ask for a change and see it as a diff, or open the Book Editor step for a genre scorecard, an editorial letter and line edits that go straight into your chapters.

  • Chapter chat shows every change as a diff you accept or reject
  • Book Editor: a genre scorecard, an editorial letter and line edits with proofreading built in
  • Every suggested replacement is accepted or rejected one by one
  • AI proofreader with several fixes to choose from for each issue
  • Edit any line yourself in the editor, whenever you like

3.Format

Format it like a real book

Pick an interior theme, a body font and a trim size in the book formatter, and export a print PDF, an EPUB and a DOCX that look professionally set. Design the cover in the same place.

  • Five interior themes and 12 embedded body fonts
  • Nine trim sizes, with front and back matter built in
  • Print PDF, EPUB and DOCX, with EPUB validation
  • A cover at the 1840 x 2784 KDP ratio, or upload your own
  • An audiobook made from the same manuscript

4.Distribute

Distribute it under your name

Take the files to Amazon KDP or any other store. The KDP extension fills the Details, Content and Pricing pages while you review each one. Share one Author Page link and collect the emails of readers who want your next book.
