The ultimate profitable service: I create fortune-telling services that keep running even while I sleep. With a service built in just one week, I generated 2 million won in revenue during the first month without spending anything on advertising. My second service, built recently in just three days, generated 340,000 won in net revenue in a single day. This is not just a simple 'click-and-go' fortune-telling service. I am in charge of creating fortune-telling services for one of Korea’s leading associations of professional fortune-tellers, and I also develop and operate fortune-telling services made using IP purchased from Naver Webtoon. Starting from cases I have operated myself, this course walks you through the process of creating a high-quality fortune-telling service for your own brand by conversing with AI—even if you have no technical background. You will implement everything from characters and stories to fortune-telling results, payment and automated delivery, and an admin dashboard, then connect customer acquisition through automated Threads posts, Meta ads, and YouTube content. This is a 'real' fortune-telling course focused not just on the fun of creating, but on monetization.
