Just Say "Do It": The AI Agent Playbook for Building and Running a One-Person Online Business

Product Hunt launch week: code PRODUCTHUNT takes 30% off at checkout, through October 31.

Koreans are obsessed with making money. So when AI arrived, we didn't play with it. We turned it into income and automation, faster than almost anyone.

Over half of Korean workers already use generative AI on the job, about twice the US rate (Bank of Korea). Korea is ChatGPT's #2 paying market on Earth. Generative AI hit 60% use there in three years; the internet was at 7.8% at the same point.

I run a one-person online course business in Korea, and AI agents do much of the daily work: posting, replying to customers, watching the site. This is that playbook, in English. Business works the same everywhere: a pilates studio in Seoul and one in Ohio get the same 11 p.m. "any trial class this week?" message.

You already pay for ChatGPT or Claude. This is the 11-step system for turning that subscription into a business you own — built by AI, run by agents.

• Find a business model you can actually run — before you touch a tool
• "Clone" yourself — decide which parts of your work to hand to agents
• Set up your agent workspace — Claude Code, Codex, a virtual machine, the cloud
• "Build me a site" — let coding agents build your storefront and course site
• Sell your knowledge on your own site, not someone else's marketplace
• Automate your marketing — five automation methods, MCP, social posting
• Train agents on your own data so they work the way you do
• Build a system that learns from what you approve and reject
• Run it all from a server (even a free-tier one), so it keeps working when your laptop is closed

Every chapter ends with copy-paste prompts and a "Do it today" checklist.

What students of the original Korean course say (translated, names left out):

"Watching lesson 14, I built the first automation of my life. With just a few words, an Instagram comic came together. For a complete beginner like me, it's a whole new world."

"To try the course in practice, I spent the whole day and finished renewing my fortune-telling app."

"Starting from the first course, I built one module at a time at home, and I recently finished my company's ERP."

"I used to pay a hosting service every month for 24/7 automation. After today's lessons I cancelled it. Even videos from outside Korea rarely teach how to set up a VPS properly."

"Honestly, each chapter took me at least 2 hours. Lots of errors. But in the end they got solved."

Who it's for: people who've used ChatGPT/Claude for months and want their own online business or side income, and will put in ~5 hours a week.

Who it's NOT for: complete AI beginners, and anyone looking for "one click = $10k/month." This book shows you the work — and how to hand most of it to agents.

What you get: PDF + EPUB, plus a prompt pack with every prompt from the book. About 32,000 words.

Want it applied to your business instead? The Done-for-You AI Automation Blueprint ($149, this ebook included): tell me how your business runs and I send back your top 5 automations, tools, costs and a step-by-step build within 48 hours.
