Every book writing tool was built for something else. Booknaut started from the book.

Subject: The Problem

Your novel is not a long document with bold headings. It never was. But every tool you've tried treats it that way, because every tool was built for something else and bent into shape for books as an afterthought.

If you've ever fought Scrivener's Compile dialog just to get a clean EPUB, or opened six applications before finding the one where you actually write, you already know. The gap in this market isn't at the bottom. The gap is at the top.

Subject: What You Get
I808.1

Structure

Chapters and scenes are objects, not formatting tricks. Drag-drop to reorder when you realize Act 2 is in the wrong place. The outline is the manuscript. They're the same thing.

II808.2

The Editor

Markdown renders inline as you type. You never see syntax, never fight formatting, never think about the editor. Built on TextKit 2. Every keystroke is instant.

III808.3

Extensible

A romance author gets character relationship tracking. A technical author gets code block validation. A poet gets syllable counting. The plugin system adapts to how you write.

Subject: Your Book on Disk

Your project is a folder of Markdown and JSON on your Mac. No database. No proprietary format. Human-readable. Version-controllable.

If Booknaut disappeared tomorrow, you'd open your files in any text editor and keep writing. That's the trust signal other tools can't offer.
