GhostAI Workshop: 3-Hour AI Editing Tools Workshop with Leanpub Founders

A 3-hour live GhostAI Workshop on Zoom with Leanpub founders Peter Armstrong and Len Epp. Learn to use GhostAI, our open-source suite of Claude Code skills that act as your AI development editor, copy editor, and structural advisor. GhostAI works at the file-system level with full manuscript awareness.

This isn't a lecture. It's a hands-on working session where you'll install GhostAI, watch live demos on real manuscripts, and run the skills on your own writing. Staff handle setup troubleshooting and book strategy; GhostAI handles the editorial heavy-lifting. Your AI editor continues working with you long after the workshop ends.

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.

• Designed for technical authors who are comfortable with the terminal
• Claude Code installed with your own Anthropic API key, and connected with terminal. This works best on macOS or Linux, but WSL2 on Windows also works.
• A GitHub account (optional) — GhostAI is public at github.com/leanpub/ghostai; a GitHub account lets you star, fork, or contribute
• Pre-event setup instructions will be sent by email
• Need help with setting up Claude Code? We recommend the Full Day Workshop — we provide setup help during the ~90 minute break between the morning and afternoon sessions
