I teach AI in Business at Western Washington University, and I built a free, case-based AI textbook with Claude and GitHub Pages: https://prof-califf.github.io/ai-in-business/ The 11-chapter digital textbook includes seven real company cases—EveryCure, Netflix, Spotify, Uber, Waymo, Airbnb, and Epic—plus chapters on AI’s environmental cost, ethics, regulation, and the future of work. Seven chapters include hands-on Python labs, and Chapter 8 has an interactive calculator that models the energy and water footprint of a reader’s own AI usage. The textbook is free, has no publisher, and costs $0 to host. The problem was that AI textbooks are stale before they ship. An 18-month publishing cycle means students can pay $200 for a book that is already two model generations behind. Textbooks also tend to teach theory first and postpone business relevance until much later. My students do not need to derive backpropagation. They need to understand why Spotify built a recommender, how it works, what broke, and what it cost—then build one themselves. My stack is Claude, GitHub Pages, VS Code, Google Colab for the labs, and n8n for the Chapter 7 agentic lab. The project started when I was assembling a reading list and could not find anything usable—only outdated textbooks and paywalled cases. I already had years of lecture notes scattered across documents. Step-by-step: 1. I locked in a framework first. I use the AI Factory model—Data → Model → Prediction → Decision → Value → loop—and run every company through it. This is the step people skip: it builds transferable skills for students and gives Claude a stable structural contract across every chapter. 2. I set up the repository before writing. I created a new repo, added `index.html`, opened Settings → Pages, and confirmed that the site deployed. Five minutes up front was better than debugging after 40,000 words. 3. I built one chapter completely and used it as the template. Each chapter is a single, self-contained HTML file with no build step or dependencies. Then I prompted Claude: "Here's my finished Chapter 1 as the format reference. Here are my notes on Uber. Draft Chapter 4 in the same structure and voice." A finished exemplar worked better than an abstract description. 4. I started from my existing material instead of using a blank prompt. Claude structured and clarified my notes, but it did not decide what I think. I rewrote anything that did not sound like me. That distinction preserved the resource’s voice and avoided generated filler. 5. I made the labs builds rather than exercises. Students reconstruct each system in Google Colab using Claude as a coding partner, then publish their work to their own GitHub repositories. They finish with artifacts. 6. I shipped an incomplete version and update it like software. I published with fewer chapters, then edit and push updates when regulation changes so students automatically get the current version.
