SaturnDesign

the design-judgment layer for AI assistants — 495 studied designs — free

Exhibit A

Your AI
can build.
This teaches
it taste.

Left alone, every AI builds the same website. SaturnDesign makes yours study 495 real designs first, commit to one direction, and get the finished page graded before you ever see it.

What your AI builds today

A crumpled printout of a generic AI-made landing page — purple gradient hero, grid of identical cards — graded in red ink with scribbles and a big REJECTED stamp
specimen 001 — one-prompt output · graded by review · REJECT, 7 named tells

Exhibit B — the loop

02

One direction

It commits to a specific look for your project, with hard rules attached:

"direction": one invented mechanism
  × one movement chosen on purpose
  × one money-surface rule
"Measured ink-on-bg = 15.04:1
  (meets the 4.5:1 floor)."

— actual compose output. This page was built against it.

03

Graded before it ships

A script measures the real page — colors, readability math, layout logic — and the grader answers PASS, or the exact fixes:

"verdict": "REJECT"
"slop_tells": [
  "purple_gradient_default",
  "uniform_bento",
  "template_headline" ]
"contrast": 2.54:1 < 4.5:1

— actual verdict on the specimen above. Nothing here is a mock-up.

Exhibit C — the corpus

495

studied designs — apps, brands, patterns, movements, copy systems, offers. Each one broken down into what to steal and what to avoid.
