FOR ENTREPRENEURS

Turn your operating playbook into a book investors, customers, and hires can quote.

Wren's Voice DNA learns from investor updates, post-mortems, Looms, Slack threads, and Notion docs, then turns them into a KDP-ready book without a ghostwriter or manuscript month.

Entrepreneur books made with Built & Written

Click any cover. Read the whole book.

Built&Written showcase books modeled for founder and operator use cases. Click any cover to inspect the interior, real typesetting, and the kind of KDP-ready playbook an entrepreneur can share.

Built into every Wren run

Nine things Wren does so you don't have to.

Built&Written is an AI book builder for entrepreneurs who already have the raw material. Wren handles Voice DNA, chapter structure, cover concepts, print formatting, and Amazon KDP export without slowing the company down.

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 → 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.

Chapter regeneration

Rewrite a single chapter from your edits without restarting the whole manuscript.

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.

Wren illustrations

Custom chapter art, diagrams, and infographics matched to your book's voice.

Outline builder

Drag, rename, delete. The structural decisions live on one screen.

Voice training

Wren refreshes your voice profile as your writing evolves over the months.

Built for the people who already have something to say

Four audiences. One book each.

Wren ships dedicated landing pages, voice profiles, and proof for each audience below — every book is sized to its reader.

For coaches

The book that closes high-ticket coaching clients on the first call.

  • Built around your existing frameworks and session language
  • Designed to hand to a prospect, not to sell on Amazon
  • Reads like the post you wrote at 2am, not a generic template tone
See more for coaches

For founders

Your playbook, printed. The asset every investor asks about but few have.

  • Distills decade-long operator knowledge into one bound book
  • Standalone proof of thinking — independent of company stage
  • Faster than waiting for a co-author or biographer to find time
See more for founders

For consultants

Turn the same proposal you keep retyping into a book that does the selling.

  • Each chapter becomes a leave-behind for a different pitch
  • Codifies the methodology you've been giving away in calls
  • Justifies your senior-rate without needing a 30-minute intro
See more for consultants

For executives

The legacy book without the 18-month ghostwriting cycle.

  • Captures the lessons you'd brief a successor on, in your voice
  • Built quietly, on your time, without an outside writer involved
  • Becomes the keynote, the board gift, the team-onboarding text
See more for executives

From Slack threads to a founder playbook

Twelve seconds. The whole journey.

Wren reads the investor updates you've already shipped, the post-mortems you've already written, the Notion docs nobody else has time to open, and turns them into a print-ready first pass in minutes. The review arc looks like this.

More movement. Fewer fake covers. The book belongs in the room.

These are modeled founder proof moments: board prep, operator floors, desk work, and after-hours review. The book stays present without asking a generated cover to do the selling.

I've been thinking about writing a book...

I've been thinking about writing a book for a really long time. About my journey and building the business. But when I saw the ghostwriter bills I'd have to pay, I said nope to myself. And here we are, AI is a thing now. I just dropped in my notes and got a perfectly outlined, print-ready book. Did a few tweaks and now I'm printing it for myself and my clients. Really powerful tool.

I wrote a book about kitchen

20 years as a head chef and the hardest part was never the food, its managing people. i had tons of notes about training cooks, handling rushes, dealing with no-shows, all that stuff nobody teaches you in culinary school. kept thinking id turn it into a book someday. pasted everything into builtwritten and it actually organized my rambling into real chapters. reads like me talking to a new sous chef which is exactly what i wanted. published on amazon in like a week. still kinda shocked i actually did it

Hi Rehmat! Fair point. Voice DNA is the part of Wren built to fix exactly that. It reads your existing writing first so the book sounds like you, not a generic voice. We'd love to show you what the draft reads like once Voice DNA has trained on your samples, and we'll dig into the word-limit issue too.

Polished Manuscripts, in Half the Time

|Built & Written

I use Built & Written as a sophisticated governance layer that allows me to audit my narrative flow, automate the tedious mechanics of punctuation, and refine the structural layout of my manuscript. It bridges the gap between raw, philosophical reflection and a polished, print-ready product by handling the administrative friction of formatting and organization. I appreciate its role as a digital editor, providing a high-level architectural view that simplifies the finalization process into a logical sequence of checkpoints. This perspective shift helps maintain creative vision while ensuring the architectural integrity of the final book. The simplicity of the platform makes the daunting process of finishing a book feel achievable, boosting my confidence to keep moving, and allowing me to focus on the heart of my message while the software handles the complexities.

FAQ

Frequently asked questions.

  • Yes. Built&Written is designed for entrepreneurs who cannot disappear for a manuscript month. Voice DNA handles the writing pass from source material you already have; you review, choose, and sharpen the book between company priorities.

  • Start with investor updates, post-mortems, Looms, Slack threads, Notion docs, voice memos, or outlines. Wren pulls source material from wherever you already think out loud and shapes it into chapters.

  • They take the thinking seriously. A founder-authored Amazon KDP book that explains your market thesis, operating principles, and lessons learned can travel further than a pitch deck when it gives investors, customers, and hires language they can quote.

  • Yes. The strongest entrepreneur books make the company evidence, not the headline. Wren helps structure the book around the thesis, playbook, or category point of view so it sells the thinking before it sells the product.

  • Pivot in the editor. Swap chapters, rewrite the angle, regenerate sections, and keep the useful parts of the draft. Built&Written works as a ghostwriter alternative for founders because the book can move as the company story sharpens.
