Why every AI-built site looks the same
The AI Slop Score is a free AI slop checker for one specific problem: sites and apps that look generically AI-generated. Ask any AI to build a page and it reaches for the same answer every time. A purple-to-blue gradient. Inter on every line. Three feature cards in a row.
Not because it is the best answer. Because it is the average one. A model predicts the most likely design, and the most likely design is the middle of everything it was trained on.
Your visitors cannot name it, but they clock it in a second. This was generated, not designed. The score tells you how much your page is giving away, and what to change.
That is the AI look. Not broken code, just the statistical centre of the web, shipped by everyone at once.
The tells that give an AI-built site away
A human designer would never leave these in. The checker looks for each one, then ranks them worst-first.
-
01
Default AI-purple
The gradient every model reaches for when no one tells it otherwise.
bg-indigo-500 -
02
Generic type
Inter, Roboto or system fonts doing all the work. The typographic equivalent of beige.
font: Inter -
03
Copy-paste shapes
The same card, the same three-icon grid, the same corners on every block.
rounded-2xl -
04
Placeholder copy
"Your headline here", "Company Name", the sample text left live on the page.
Lorem ipsum -
05
Filler phrasing
The tell-tale AI words and clichés sitting in your actual copy.
"unlock the power of" -
06
Skipped structure
Missing alt text and the accessibility corners AI cuts. Invisible to you, obvious to a screen reader and to Google.

How the AI Slop Score works
No screenshots, no guesswork. It reads the page the way a browser does.
-
1
Paste your URL
Any live page: your landing page, your app, a client's site.
-
2
It renders and reads your code
The tool loads the real page and reads the CSS and markup you shipped. Only the first-party code you control, never your analytics or ad tags.
-
3
You get a score and the fix
A 0 to 100 taste score (higher is cleaner), every tell ranked worst-first, and one copy-paste brief that fixes the lot.
Fix the AI look without a designer
Knowing your site looks generated is half of it. The report hands you the other half: one master brief. A single prompt that names every tell on your page and tells the AI exactly how to fix it.
Paste it back into Claude, Lovable, Bolt, v0 or Cursor alongside your code, and ship a version that reads hand-built. No design degree, no starting over. Just the specific changes that move you from "reads machine-made" to "reads hand-built".
It is built for people who ship with AI. You made something real and it works. This is the tool that says why it still feels generated, and hands you the prompt to fix it before it goes in front of users, investors or paying customers.
Where the score comes from
The engine is a 29-rule taste linter. The tells it checks are the same ones Anthropic's own frontend-design guidance tells Claude to avoid: no Inter, no Roboto, no purple-on-white gradient, no placeholder left in the shipped page.
The first site it ever graded was this one. I rebuilt joshuasnoddy.com against these exact rules before I asked you to run it on yours.
I'm Josh Snoddy. I build software live with Claude, and teach other people to do the same.
Questions builders ask
Design generated in bulk and left at the AI's default: generic layout, stock components and filler copy. In web design specifically, it is the purple-gradient, Inter-font, three-cards look that comes from prompting an AI without direction.
Look for the defaults: a blue-to-purple gradient, Inter or system fonts, identical card grids, rounded corners everywhere, and placeholder text left in. The AI Slop Score checks for all of them and scores how many are showing.
Yes. If it has a live URL it can be checked. The tool grades the page you shipped, whatever built it.
Your score and your single biggest tell are free, every time. The full findings and the copy-paste fix brief unlock with a free account, or a one-off £5 if you would rather skip the account.
No. The tool reads only the public page you paste, grades the first-party code you control, and hands the result to you. It is not a crawler and it does not touch anything behind a login.
Everyone has AI. Not everyone has taste.
