What the detector looks for
AI website builders and coding agents share a handful of habits. Each one is harmless alone; together they make a page look like every other generated page. The detector reads the page and its stylesheets and checks for these:
- Purple-to-blue gradients, in backgrounds, buttons and especially headline text.
- Emoji as icons: 🚀 ✨ ⚡ in headings, feature lists and buttons.
- Buzzword copy that could describe any product: “unlock the power”, “seamless”, “supercharge”, “to the next level”.
- The three-card feature grid: icon, heading, two lines, three times.
- Everything centred, including long text and cards.
- Glowing blobs and frosted glass behind the content.
- The same big rounded corners and soft shadows on every element.
- Generic buttons like “Get started” and “Learn more”, vague social proof (“Trusted by 10,000+ teams”), placeholder content and only the default font.
How the score works
Each habit has a weight: the ones people notice first, like gradients, buzzwords and emoji, count most. The score is how much of that weight the page shows, from 0% (looks hand-made) to 100% (full AI slop). Under 20% is a page with its own character; 20–44% has a few AI tells worth fixing; 45–69% looks noticeably generated; 70% and up is the full template.
It isn't an AI detector for who built the page. It measures the design habits, which is what visitors actually react to.
How to make a site look less AI-generated
Most fixes are small, and they share one idea: replace the defaults with decisions. Use your brand's own colour instead of a gradient. Write what the product does instead of how amazing it is. Show the product instead of three icon cards. Left-align anything people read. Then look at how a few real products in your category handle the same sections, and borrow their decisions, not their pixels.
A prompt for your coding agent
Paste this into Claude Code, Cursor, Codex or Copilot along with your detector results:
Our site looks AI-generated. Fix these without changing what the page says: - Replace purple-to-blue gradients and gradient text with our brand colour, mostly solid. - Remove emoji used as icons; use one icon set, or none. - Rewrite headings and buttons in concrete words: what the product does, for whom, and what each button does. - Left-align sections and cards; centre only short hero text. - Replace the three-card feature grid with one real screenshot or a short demo of the product. - One corner radius for the whole page; shadows only on things that float. Before changing anything, look at how 2 or 3 real products in our category handle their hero and pricing sections, and say which decisions you're adopting.
Questions
What is AI slop in web design?
It's the look that AI website builders and coding agents fall back on when nobody gives them direction: purple-to-blue gradients, glowing blobs, emoji as icons, three identical feature cards, everything centred and copy like "Unlock the power of…". Any one of these is fine on its own; together they make a site look generic and generated.
Is the AI slop detector free?
Yes. It's free and needs no account. It checks public pages only, a few times an hour per visitor, and doesn't save the address you enter or the result.
Does it tell me whether AI made my site?
No, and nothing can reliably. It measures how many of the common AI-generated design habits a page has. A human can build a page full of them, and a site made with AI can score low if someone gave the agent real direction.
Why does my score look too low?
Some sites build most of the page in the browser after it loads, so the first version the detector reads is nearly empty. The result says when that happens. Checking a page that's rendered on the server, or a specific landing page, gives a better reading.
How do I stop my coding agent from producing AI slop?
Give it evidence instead of adjectives: your own design system, a clear brief, and real examples of how good products solve the same screen. That's what UXKIN does: it gives Claude, Cursor, Codex and other agents real app screens, user flows and website design systems to work from.
Put it to work
UXKIN gives your coding agent real app screens, user flows and website design systems to work from, so what it builds looks like a real product, not the same AI template. Browsing the library is free.
