What this does

AI assistants can build websites, but left alone they all build the same one — same purple gradient, same grid of identical cards, same font. SaturnDesign fixes that in three steps:

Study first. Before building, your assistant reads real examples from a library of 495 studied apps, brands, and pages — what works, what to copy, what to avoid.
One clear direction. It commits to a specific look for your project instead of the default template, with a concrete checklist to build against.
Checked before it ships. The finished page is graded: does the text pass readability math, does anything read as “an AI made this”, did it follow the direction? A pass means done. A fail comes with the exact fix list.

Three paths. All free. An AWAKE account opens the full DNA on every card. Agents stop guessing generic UI.

Prefer to see it? Open the Studio — the in-browser desk: type a brief and watch the direction, tokens, and a live styled preview land in front of you; load any page and the grader pins its verdicts right on it. Everything your assistant does through these paths, made visible.

Why this beats a screenshot library

Free, actually. The MCP and hosted API work anonymously; a free account unlocks the rest. No paid-plan gate, no trial wall.
No OAuth dance. Anonymous, or one Bearer header. Works in anything that speaks Streamable HTTP — including plain curl.
Judgment, not a browse pile. Screenshot tools return things to look at; compose returns a committed direction with hard rules and DTCG tokens. Deciding what to keep and what to cut is the product, not your problem.
The loop closes. References inspire the build — then review grades the finished page with measured evidence. Nobody else grades.
Nothing depends on your client's renderer. Outputs are text and tokens in every client equally; the visual surface is the Studio — a URL, not a plugin.

Works with: Claude Code · claude.ai connectors · Cursor · Codex · Antigravity · any MCP client · plain HTTP.

2 · One command

Local MCP (Cursor / Claude Code)

Installs the agent pack to ~/.saturndesign/agent and prints MCP config with paths filled in. Add a key from your account and it reads full DNA too.

curl -fsSL https://izzydesign.dev/design/agent/install.mjs -o saturndesign-install.mjs && node saturndesign-install.mjs

Windows: install.ps1 · macOS/Linux: install.sh · or download install.mjs and run node install.mjs

Hosted API

3 · Free account

Full DNA on all 495 cards
