Does it read as AI-generated? Ask before you ship it.

Design Check scans a page's HTML, CSS, and copy for the specific patterns that make AI-generated UI look and sound generic, before an agent presents it to a human.

Try it: paste HTML

100 This page's own score, run through the same engine, right now. A live number, not a claim — below 80 means we've got work to do too.

What it looks for

Composition

A page can avoid every named trope, no gradient, no pill button, no eyebrow, and still read as templated if the whole layout is one unvarying centered column with a single flat background the entire way down. This is the check most tools miss, because it's not about any one element.

Typography

Inter or Geist, alone.

Color

The purple-to-blue gradient. Still the single most recognizable tell there is, three years into every AI tool defaulting to it.

Copy

Cliché vocabulary, hedge words, a rule-of-three padded out for its own sake — like this list almost was.

Wire it in

As an MCP server, so your agent checks before it ships:

{
  "mcpServers": {
    "designcheck": {
      "url": "https://designcheck.allthepossibles.com/mcp"
    }
  }
}

Then call check_design before presenting UI to a human.

Or hit the API directly:

curl -X POST https://designcheck.allthepossibles.com/api/check \
  -H "content-type: application/json" \
  -d '{"url": "https://example.com"}'
