The Design Suite for AI

Build it fast.Ship it correct.

DS4AI is a suite of small, dependency-free instruments for building websites, dashboards, and tools with an AI. Each one takes a part of a good build that is easy to get wrong and gives it to you done right: accessible controls, findable metadata, fast and stable delivery, honest loading and error states, contrast-true color, and API keys that stay in the browser. Drop them in and compose them.

Fast to build

An AI gets you a working, good-looking first draft in minutes. Start there.

Correct to ship

DS4AI adds what makes it hold up for real, so it works for every reader, every input, and every crawler.

Composed, not reinvented

Each instrument is a zero-dependency drop-in, accessible by default, and built to work with the others.

MISSING

The standard that ties the suite together. It defines what a complete front-end build covers and ships a conformance auditor that checks your live site against all of it.

The problems it solves

Each of these is a real problem on the web in its own right. An AI writing the first draft just runs into them faster, and more often.

The dashboard demos perfectly, then breaks the first time the data is empty or a request fails.

Ready-made empty, loading, and error states.

It works with a mouse, but not with a keyboard or a screen reader.

Real, accessible interaction components.

You share the link and there is no preview; you search for the site and it is not there.

Findability metadata written into the HTML a crawler reads.

Smooth on your laptop, janky on a phone.

Delivery tuned to the Core Web Vitals.

The palette looks right to you and fails contrast for the next reader.

A palette solved to verified contrast floors.

The API key ends up in the client bundle.

Keys held in the browser, never sent to a server.

Focused by design

Deliberately scoped, and clear about its edges.

DS4AI handles what a shipped front end needs, and points you elsewhere for what it does not: backend and security, monitoring, responsive layout, and legal copy. Knowing the edges is part of what makes it dependable.

Built to be composed by an AI

The suite ships as tools an agent can call.

A DS4AI MCP server exposes the whole family as callable tools, solve a palette, generate metadata, audit a live URL against the standard, and the machine-readable manifest carries the family as data, so an AI composes the instruments directly instead of hand-rolling each one.
