I've added 2 lessons on Substack to the Claude HQ classroom. Winning with Substack and Claude & Substack. Both are in Phase 5 of the Claude HQ lesson and they work as a pair.. Start with Winning on Substack if you want the platform itself: what it actually is, why readers subscribe and pay, the writing styles that build a real following, and how to turn on paid the right way. Then Claude and Substack picks up from there and shows you how to run the whole thing through your four curriculum Projects, your voice, your audience research, your monetization copy, and a pipeline that turns one post into Notes, a carousel, and social posts.
