I built my site like it’s 2005 and I regret nothing.

There’s a snake game on the 404 page that actually moves. A terminal that types itself out. And somewhere underneath all that — 14 years of UI/UX work and a design subscription, if you’re into that sort of thing. Vibe-coded, made with love.

Your support queue is growing faster than your team can handle. What if you could resolve 60% of support tickets automatically with AI? I'm building Relay AI, an AI support agent trained on your docs, tickets, and product. It answers customers in seconds, and escalates to your team only when it should.

Settle this for me. Which one do you actually build with in 2026: ChatGPT or Claude?

Not "which is smarter on benchmarks". Which one is open in your other tab when you are shipping real work for a client.

My honest take after using both daily for client projects: ChatGPT for speed, images and quick answers. Claude for long documents, code and anything where it must not make things up.

Vote, then tell me in the comments what you use it for. Designer, dev, writer, founder, I want all of you.

Whichever wins, I will use it to build the free starter kit I promised in my last poll and post the full prompt log.
