I can't code. I built 5 AI services in 3 weeks.
I'm a 17-year exhibition curator from South Korea. I have never written a line of code in my life. No Python, no JavaScript, nothing. I don't even know what half of those words really mean.
In January 2026, I built 5 AI services and 6 websites in 3 weeks. By myself.
I still can't believe I did this.
What I Built
DeckGuard is a pitch deck risk analyzer based on Y Combinator standards. I tested my own old pitch decks on it and it destroyed every single one. Not a single kind word. Somehow that made me proud. Built in 1 day.
Tomorrow Me generates beautiful cards with messages from your future self based on what you type about how you're feeling. I built the basic version in 2 days, but fine-tuning took 10 more days. I cried twice during those 10 days. That's a whole story I'll tell later.
INNERLOG is a literary journaling service set inside a 19th-century salon. You type your feelings, it finds a matching passage from classical literature, then rewrites your emotion in that author's style. I wrote every single line of copy on this site myself. Built in 1 day.
FREQUORA shocked me the most. It turns your emotions into cosmic soundscapes mixed with whale songs and rain. My mom is the harshest critic I know, and she listened to a test track and couldn't breathe. Built in 1 day.
ART WIZARD is an experimental AI art lab. The first experiment is called DISCORD, where AI judges humans instead of the other way around. Three AI judges with three different personalities, and they do not hold back. Built in 1 day.
What I Used
GPT, Gemini, Claude, Manus, DALL·E 3, Stability AI. GitHub, Vercel, Supabase for deployment. Paddle for payments. 23 domains. 52 trademark applications.
I planned every single service in a 1-hour conversation with GPT and Gemini. In bed. Right before falling asleep. The next morning I'd start building.
How
I didn't follow tutorials or watch YouTube guides. I just talked to AI the way I talk to people.
"I'm not a developer. What can someone like me actually build and sell online? Only things with real market demand." GPT and Gemini each gave me lists of over 10 ideas and swore anyone could do it. I picked what excited me, then made them compete against each other. "This one said X, why are you saying Y?" That's still my favorite method for filtering out nonsense.
For code, I used Claude. For design, I used Manus. Manus designs like a drunk Italian art student who accidentally broke the system. Wild, chaotic, way too much of everything. But underneath all that chaos, there was something genuinely beautiful. Claude on the other hand gives you clean, boring designs every time. So I took Manus's chaos and shaped it into something I actually wanted.
What It Actually Felt Like
Building DeckGuard was pure adrenaline. I made this. In one day. The high was unreal.
Tomorrow Me nearly broke me. Manus rolled back 10 hours of my work without warning. I cried and kept working. Then it happened again, 5 hours gone. I cried again and kept working. After surviving two rollbacks like that, a 1-hour rollback didn't even scare me anymore. Funny how that works.
INNERLOG came together when I realized I could build a whole world, not just a service. A 19th-century literary house with a butler, a golden door knocker that glows when you hover over it, parchment-textured pages. Making that tiny door knocker glow took way longer than I'd like to admit.
FREQUORA was the biggest surprise. I didn't want to make a sound service. I didn't think I could. GPT and Gemini kept pushing me, saying it'll take one day, just try it. So I did. And when I heard dolphins echoing through cosmic frequencies that I created, I got chills. That was my universe. I made that.
The Honest Numbers
Revenue is $0 so far. Payments just got approved and services are going live now. Team is just me. No developers, no designers, no co-founders.
What's Next
I'm writing a book about all of this. It's almost done.
All 5 services are launching with paid plans in February and March 2026. I'll share the numbers as they come in, good or bad.
I spent 17 years planning exhibitions for other people's visions. Now I'm building my own.

I'm Haerang. I build AI products at the intersection of technology and human emotion. Ask me anything, especially if you think you can't build things because you're "not technical." I was exactly you, one month ago.
