Make your site look designed, not generated.

Paste a link. We circle every AI default on your page, from the gradient headline to the three identical cards, and write the fix as a prompt for whichever AI tool built it.

documented patterns in an open library, with the cause and the fix for each.

MIT licensed, updated every week

Find it. Name it. Fix it.

Drag the line. Same product, same content, before and after one round of fixes. Both grades are real scans.

  1. 1
    We load your page in a real browser

    The rendered page, on a laptop and a phone, not just the code. About ninety seconds.

  2. 2
    Every default gets marked and named

    Each mark links to its entry in the library: what it is, why AI tools make it, who it hurts.

  3. 3
    You get the fix as a prompt

    Paste it into Lovable, Cursor, Claude or any AI tool, then scan again.

The demo page after the fix: serif headline, a real product timeline, no labels or emoji.

Same product, before and after the fixes. A demo site built the way AI builders usually build it, then reworked following Slop Score’s findings. Both grades are real scans.

Fix prompt A3 · Three Identical Feature Cards

Fix "Three Identical Feature Cards" (A3) on my landing page. Rank the features and give the lead one more space, an actual screenshot and a longer explanation. Use different forms for different content: a comparison table, a list, a single annotated image.

In 2016, under 1% of launch pages carried these patterns. This year, 47% do.

A design check, not an AI detector.

Patterns, not people
We never say a person used AI. We point at design choices that became common after AI site builders arrived. People made them long before.
Measured, not guessed
Every rule is weighed by how much it spread across real launch pages. Things that were always common count for little.
Private by default
Code your agent sends is checked and thrown away. Never stored, never used for training.

Make it look like everyone’s yours.
