About
Courses you learn by doing, not watching.
Why this site exists, and who’s behind it.
What this is
claudecoworkcourse.com is a marketing and course-delivery site for hands-on AI training. Every course — the free Claude Cowork flagship and the 12 paid courses in the library — is a downloadable lesson file you work through inside an AI assistant (Claude, ChatGPT, or Manus). Lessons use a STOP/USER format: the AI teaches a concept, then you respond with real work on your own tasks. No videos, no lectures, no certificates — just practice on things you actually need to get done.
Who runs it
This site is run by Clarence T. Archibald IV of C4 Growth Solutions (Chicago, IL), operating under the legal entity C4 Holding Company LLC. Clarence builds the courses, writes the content, and answers support requests personally — there’s no support ticket queue.
Why free-first
The flagship Claude Cowork course is free with no signup wall because the fastest way to prove a hands-on course actually works is to let people try it. The paid course library exists for learners who want to go deeper into a specific skill — prompt engineering, freelancing, professional writing, data literacy, financial modeling, and more.
