Marc Lou@marclou · Feb 20, 2026I made 4 apps in 4 days. AI turned my life into a game. I walk around with ChatGPT, dump my thoughts, we iterate, and it pushes me to think better ideas. When an idea feels solid, I write a detailed prompt for Cursor or Codex. 90% of the time, it works in one shot. Then comes the tweak phase. AI still isn’t great at UI, so that’s where I spend most of my time. It also adds too many useless elements (icons, random colors, extra stuff), so I remove a lot. After 30–40 tweaks, it usually looks good enough. These are one-time projects, so I optimize for simplicity: very explicit app name, ultra-short headline, one CTA, a demo, and a clean OG image. That part is still manual. AI isn’t great at it yet. Building apps in 2026 is addictive. AI removed the parts I don’t enjoy, like writing code. Now I just think. The only part I still dislike is the hardware. I hate sitting on a couch staring at a 15-inch screen. I want to stand in an empty room with walls made of displays, walking and talking while I build.
