Challenge

I write Second Ladder Intel, a newsletter with 48,200 subscribers and a 47% open rate that I produce in about 30 minutes a day. For months readers kept asking the same thing: how do I do this for my own topic. The opportunity was to package the exact system I run into a paid course and sell it to an audience I already have, my 48K list plus around 2,000 dormant leads, at close to zero acquisition cost.

The real problem was production. Building a real course, the curriculum, the lessons, the visuals, and the funnel around it, normally takes a small team and weeks. I wanted to see how far one person could take a sellable course with Claude doing the heavy lifting, without it reading like generic AI output or looking half-finished.

What I built

A complete, sellable course called The 30-Minute Newsletter: five modules, 27 lessons, and quiz checkpoints, fully structured in a course platform with a branded editorial image on every single lesson. The teaching copy is written in my own spoken voice so it reads like me, not like AI, and the structure is built so my recorded videos drop straight into each lesson.

Around the course I also built the funnel: a conversion-focused sales page, a live landing page on my own domain, and a repeatable build-and-deploy pipeline so launching the next page takes minutes instead of a rebuild.

How it works

I started from a written course outline and had Claude scaffold the whole thing programmatically: every module, section, lesson, and quiz created in the course platform through its API, in one pass. Then I generated one consistent editorial illustration for each lesson so the course looks cohesive front to back. The part that matters most is voice. I gave Claude my actual video-script voice guide, the way I talk on camera, so the lessons read like a person explaining something at a dinner table, not a polished AI essay. Video lessons slot into the same place as I film them.

The funnel runs on its own small pipeline. Copy starts as plain markdown, mirrors into Notion so I can edit the words like a document, then becomes a single self-contained HTML landing page in a chosen design. It ships to Cloudflare Pages as a zipped static site, live on a custom domain with free, privacy-friendly analytics. I packaged that flow into a reusable agent, so the next page or the next course launch reuses the same machine.

The stack

Claude in Cowork mode as the build layer, Mini Course Generator for the course itself, Notion as the editing surface, Cloudflare Pages for hosting and analytics, and Beehiiv plus Stripe for delivery and checkout. Image generation handles the lesson visuals. The point of the stack is that it repeats: the same approach builds the next course or ships the next landing page without starting from scratch, which is the real asset here.

Results

This is brand new, so here is the honest version. The full course is scaffolded and ready for content, every lesson is illustrated, and the sales page is live at newsletter-course.pages.dev. It is designed to convert my 48,200 subscribers and roughly 2,000 dormant leads at $47 and $149 with zero ad spend, modeled around a few hundred buyers in the launch window. Real numbers go here once the launch runs.
