The Slop Index

SLOP
or NOT

A swarm of hand-tuned detectors reads your page the way a designer would: type, colour, spacing, copy, craft. You get a score, a verdict, and the exact pixels behind every finding.

Live activity: sites scanned, repos patched, slop addressed.

a swarm of detectors, six flavours

Working UI and UX designers built every detector by hand, tuned it, then froze it. No language model touches the score, so the same page earns the same number every run, captured at three viewports and read across six detector families.

where you land

Every tell we catch adds its weight to your score, and nothing else touches it. Land near 0 and your page is clean; anything near 100 is pure slop.

every finding, cited

Every finding is written in plain English first, then backed by the exact measurement we read off your page. The detector name sits underneath so you can look it up, but you never have to.

What we found

  • That purple-to-pink gradient behind your headline creates a distinctly AI-generated impression

    Almost certain

    A 480px hero gradient running violet into pink, measured at precise pixel boundaries

    colour.violet-pink-hero-gradient

  • One font does all the work

    Almost certain

    Every piece of text on the page uses Inter exclusively

    typography.sole-generic-sans

  • Your feature blurbs are all the same length across the grid

    Fairly sure

    Six cards within 1.333 words of a 6.7-word mean, all inside a flex container

    copy.uniform-feature-description-length

  • Motion is absent, lazy elsewhere

    Worth a look

    200ms transition applied uniformly to 23 elements across the layout

    craft.no-motion-or-transition-all

the fix is the point.

Knowing your page looks AI-made costs nothing. Getting it fixed runs on credits you buy once and keep forever, starting at the price of one coffee run.
