The world's first placebo air conditioner. Cool your room psychologically with virtual fans, AC units and other cooling devices. Zero electricity. Zero refrigerant. Just vibes. Built entirely with Claude through vibe coding.
Hi everyone! 👋
A few nights ago it was unbearably hot and I couldn't sleep.
Instead of buying an air conditioner like a sensible person, I opened Claude and asked myself:
"What if I could trick my brain into feeling cooler?"
That silly idea became reFresco.
It's a collection of virtual cooling devices that don't actually cool your room—but might cool your mood.
The entire project was built through vibe coding with Claude in a single evening. I didn't write a single line of code manually.
I'd love to know:
• Did it make you feel even slightly cooler?
• Which device should I add next?
• What's the weirdest thing you've vibe-coded recently?
Thanks for checking it out ❤️
