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

What is GhostAI Workshop?

A 3-hour live GhostAI Workshop on Zoom with Leanpub founders Peter Armstrong and Len Epp. Get Early Beta Access to GhostAI, a 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.

What is GhostAI?

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. You get lifetime access as part of this workshop.

  • /ghost-review — Development editor: reads your full manuscript structure, provides feedback on organization, flow, pacing, gaps, and repetition
  • /ghost-edit — Copy editor: line-level editing for grammar, clarity, tone, and technical accuracy on individual chapters
  • /ghost-draft — Writing assistant: generates a first draft from your outline
  • /ghost-expand — Writing assistant: expands bullet points and notes into polished prose

Requirements

  • 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.
  • GitHub account — after purchasing, we'll add you as a read-only collaborator to the GhostAI repo so you have access before the workshop starts
  • 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

What's Included

3-Hour Live GhostAI Workshop on Zoom ($199 value) — hands-on with Peter Armstrong and Len Epp. Watch live demos, then run GhostAI skills on your own manuscript.

Early Beta GhostAI Access ($399 value) — be among the very first authors to use GhostAI. Your AI editor continues working with you long after the workshop ends.

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.

    Author, Trello Dojo
