Show HN: I built this toolbox with AI – never wrote a line myself

https://tool.hikun.me/ko
2•harrykoreanlee•2h ago
Hey HN! I work at a game company and after staring at code all day, I didn't want to write more at night.

So I used Claude and Cursor to build this — architecture, design, infra, CI/CD. I just directed and reviewed. Took a few weekends.

It's a collection of tools I personally Google all the time: JSON formatter, image resizer, timestamp/timezone converters, UUID generator, QR code, and ~30 more.

Happy to answer questions about the AI workflow or anything else.
