What is Book Bootcamp?

6-Week AI-Powered Book Bootcamp. Pay $1999. Show up for 6 weeks. Finish your book. We hand you $1999 back as a service credit. The bootcamp is literally free if you do the work. You get hands-on coaching on GhostAI — our open-source (MIT) suite of AI editing tools built on Claude Code — as your personal development editor, copy editor, and structural advisor. Whether you're stuck at 20% or 80%, this program gives you the structure, AI tools, accountability, and expert guidance to get it done.

Win Your Money Back: Show up for every session or finish your book and you earn a $1,999 service credit which you can use toward Publish on Amazon, CourseAI Pro or GlobalAuthor Standard (each of which costs $1999), or applied toward GlobalAuthor Pro or GlobalAuthor Max.

This isn't generic advice. Your coach is a Leanpub founder, either Peter Armstrong or Len Epp, who know Leanpub inside and out. Plus, GhostAI gives you AI-powered editorial feedback between sessions — development editing, copy editing, and structural review on demand. Every live session is focused on removing the specific obstacles between you and a finished book. Writing, formatting, publishing workflow, marketing strategy — whatever's blocking you, we'll work through it together. Groups are capped at 8 authors so everyone gets real attention.

How It Works

Over 6 weeks, your group meets for a 90-minute call every week. Groups are small — maximum 8 authors — so every person gets a hot seat every single call. This isn't a webinar you watch. It's a working session with a strict format: teaching, individual coaching, and public commitments.

Every Call: 90 Minutes, Interactive Coaching

Every single week, you get help. This is not six 90-minute lectures you watch passively. Every call is an interactive working session with a Leanpub founder and your fellow authors.

Individual attention for everyone. With a maximum of 8 authors per group, every person gets direct coaching every call — on writing, publishing, formatting, marketing, or whatever is blocking you.

Accountability that works. You'll share your progress, get feedback on your work, and make commitments for the coming week. The group keeps you on track to finish your book.

GhostAI has a certain set of skills…

GhostAI is a suite of Claude Code skills purpose-built for book authors. Unlike web-based AI tools that work on snippets of text, GhostAI operates at the file-system level — it understands your full manuscript structure, maintains context across chapters, and integrates directly with your writing workflow. GhostAI is open source under the MIT license.

Getting Started

  • /ghost-start — A conversational onboarding for your book. GhostAI interviews you about your topic, your audience, and what you're trying to accomplish, then builds a full chapter outline and sets up your manuscript so you can start writing immediately. No blank page.
  • /ghost-outline — An in-depth chapter planning session. Goes beyond a flat table of contents: challenges your structure, asks what each chapter is really trying to do, and helps you decide what deserves a chapter versus what belongs as a section or a callout. Good for restructuring an outline you already have or building one from scratch.

Writing

  • /ghost-draft — Turns an approved outline into a first-draft chapter that sounds like you. GhostAI analyzes your existing writing to profile your voice (sentence rhythm, vocabulary, tone) and uses that profile when drafting. You edit, rewrite, or keep whatever lands.
  • /ghost-expand — Takes rough notes, bullet points, or stream-of-consciousness jotting and expands them into finished prose. Preserves your intent and phrasing where it works, smooths what doesn't. Best when you know what you want to say but haven't put it into flowing sentences yet.
  • /ghost-interview — Inverts the usual writing flow. GhostAI interviews you with short questions about a chapter or section, you answer in your own words (typed or via voice input like Wispr Flow), and the transcript becomes prose with your verbatim phrasing leading. Best when you know the material cold but the page won't sound like you, or when you want to talk a chapter into existence rather than type it. Transcripts are saved alongside the manuscript and can feed back into your voice profile.

Editing

  • /ghost-review — A development editor that reads your entire manuscript, not just a chapter. Catches the problems authors and beta readers miss on first pass: a concept introduced in chapter 2 but defined in chapter 5, an argument that stalls in the middle, the same point repeated three times across different chapters, pacing that drags or rushes. This is where GhostAI's cross-chapter memory matters most.
  • /ghost-edit — A copy editor for one chapter at a time. Catches grammar issues, flags awkward sentences, and suggests cleaner phrasing without flattening your voice. Runs a publish-readiness checklist before you ship: broken links, missing images, typos, inconsistent capitalization, placeholder text you forgot to fill in.

Progress

  • /ghost-status — A dashboard for your book at a glance. Word counts per chapter, estimated reading time, chapter length balance (are any chapters three times longer than the rest?), how much is drafted versus still outline. Also estimates costs for running the other GhostAI skills against your current manuscript, so you can budget before kicking off a full review.

Requirements

Book Bootcamp includes GhostAI, which requires Claude Code (terminal-based AI tool) with an Anthropic API key. macOS or Linux required (WSL2 on Windows is fine). Setup instructions will be provided before your first session.

Win Your Money Back Guarantee

We call it Win Your Money Back because completing the program is the win. Show up to every session, or complete and publish your book at 100% on Leanpub — and you earn a $1999 service credit toward Publish on Amazon, GlobalAuthor Standard, or any Leanpub author service. Publish on Amazon is $1999, so the service credit covers its full cost. You literally cannot lose.

60-Day 100% Happiness Guarantee

Within 60 days of purchase you can get a 100% refund on your Book Bootcamp purchase ($1999), no questions asked. If you request a full refund, you will lose the $1999 service credit.

We're so confident in Book Bootcamp that we're happy to offer a full money-back guarantee. You can only find out how good something is by trying it, and because of our 100% money-back guarantee there's literally no risk to do so!

Leanpub authors love Leanpub.

We're authors too, and we built Leanpub to be the platform we would love to use. It turns out, we weren't alone...

  • As an academic, I like Leanpub because it lets me write and get my ideas out there quickly. Leanpub is simply the best place for publishing my books.

    Roger D. Peng
    Associate Professor of Biostatistics at the Johns Hopkins Bloomberg School of Public Health
  • Leanpub's book-creation tools allowed me to focus on creating the types of books I wanted to write instead of worrying how to create my own book publishing toolchain. I have never regretted using Leanpub to publish my ebooks.

    Daniel Root
    Author, Trello Dojo
