Chapter regeneration
Rewrite a single chapter from your edits without restarting the whole manuscript.
What's inside
Everything you need to publish.
From raw ideas to Amazon-ready files. Voice DNA, sequential drafting, cover design, KDP-ready export. All in one platform, none of them requiring you to learn a new app.
Six headline features below, and more in the grid. None of it requires you to learn a new app.
Voice DNA: Wren learns how you write
Paste your existing writing: LinkedIn posts, podcast transcripts, blog drafts. Wren extracts three layers (sentence rhythm, vocabulary, explanation style) and writes every chapter in your voice. He won't insert filler or invent phrases you've never used.

Sequential drafting with Wren
Paste your notes, outlines, or rough ideas. Wren structures them into polished chapters that sound like you wrote every word. Sequential mode keeps chapters connected; chapter regeneration is one click away.
Professional Formatting
Skip the $2,000 interior designer. Choose your book size and get print-ready files with correct margins, typography, and page numbers, automatically.
Cover Design
A professional cover is the difference between a click and a scroll-past. Generate 300 DPI covers that match your topic, tone, and audience.
KDP Launch Co-pilot
When the book is done, Wren writes the whole Amazon listing: title, subtitle, a full description, seven keywords, and two categories, so publishing is a paste, not a research project.
KDP-Ready Export
One click to PDF, ePub, or Kindle, all meeting Amazon KDP specs. No back-and-forth with formatting errors or rejected uploads.
Built into every Wren run
Nine things Wren does so you don't have to.
Each one solves a specific reason coaches, founders, consultants, and operators give for not finishing their book. None of them require you to learn a new app.
VOICE DNA
Reads your existing writing, then writes new chapters in your exact voice.
Wren ingests your LinkedIn posts, podcast transcripts, newsletters, and notes. The voice profile updates as you write. The draft comes back recognizable to anyone who follows your work.
- Pulls from any platform, even messy export files
- Tone, cadence, banned phrases tracked per author
THE WIZARD
Five minutes from notes to a structured 200-page draft.
Paste in what you already have. Wren assembles an outline, fills the chapters, and hands you something you can read in the time it takes to make coffee.
- Outline to first draft in minutes, not weeks
- Stays in your voice profile from the first chapter
KDP EXPORT
Files that pass Amazon's checks the first time.
Interior PDF with the correct margins and bleed. Cover wrap with spine width calculated from your page count. ePub for Kindle. Upload, approve the proof, list it.
- 6×9, 5.5×8.5, and other KDP trim sizes
- ISBN, pricing, description checklist in one place
Six more things, while you're here
Everything else Wren ships out of the box.
Cover design
Three editorial concepts on first generation, refined with type and palette tweaks.
Print formatting
Correct margins, gutters, bleed, and page numbers. Calculated automatically.

Print PDF, EPUB, and a full KDP package, checked and ready to upload.

FAQ
Questions about features.
No. Every feature is built around plain text input and visual previews. There are no Adobe-style export menus, no plugin installations, no fonts to license.
Yes. Every word, the cover, and the exported files are yours under copyright. You publish on your own Amazon KDP account and keep 100% of your royalties.
Wren is designed for 200-300 page non-fiction books. Manuscripts up to 80,000 words run smoothly. Longer projects may need chapter-by-chapter regeneration, which is built in.
Every feature is optional. Voice DNA is the heart of the product, but you can skip the wizard, use your own cover, or import a finished manuscript directly into the editor.
