At least, it's missing the cargo cult telltales like the beige or unreadable neon hax0r dark mode theme, that console looking font with three different sizes and tiny headings, formatting vomit with italics/bolding every other word, useless cards/animated colored dots, scrolling text, excess boilerplate text on every surface, useless generated tags/categories/chips everywhere, etc that plague the designs of the last year.
Overall it's clean and modern (and the interactive table actually has content not pointless filler). It definitely wouldn't have triggered my visceral slop reaction and therefore wouldn't bother me if I later learned the dev used AI to make it.
I can't speak for everyone, but personally my issue isn't the use of AI at all (I use it myself), the problem is being able to recognize a carbon copy Claude/Codex design in <5 seconds. At that point I can't help but assume it's just slop that was fired off with a couple prompts and not worth my time engaging any further.
(Mostly) the same with prose. But that's playing with fire a bit because while a website/app might have a utilitarian purpose, I will have zero motivation to continue reading text I didn't prompt myself once I suspect it's from an LLM. There's just too much spam now to give benefit of the doubt unfortunately. The writing on your site doesn't scream LLM either though so I think you're good on both fronts.
It's like the saying "if you're explaining you're losing": once the seed is planted that it's AI, it's extremely hard to successfully argue your identical Claude-designed site is the exception that deserves users' limited time. Putting in some minimal thought and care in advance to avoid that first impression means fewer of those arguments with potential users experiencing slop fatigue like me. Anyway, nice job!
