Design that's verified, not generated.

An AI web-design agent that renders production markup against deterministic quality gates. It draws the real screen in a headless browser and proves it's accessible, on-system, and shippable — before it can pass.

The pipeline

Three gates between a prompt and a shippable screen.

DESIGN

Composes from a locked system

No freestyling. It assembles your real components and tokens, so the output already speaks your design language.

RENDER

Draws the real screen

It paints the actual markup in a headless browser at every breakpoint — not a static mock that lies about reflow.

VERIFY

Gates before it can pass

Contrast, hierarchy, and a11y are checked deterministically. Fail a gate and it doesn't ship — it iterates.

The gate report

A pass is a receipt, not a vibe.

Every render ends in a deterministic report. If a check fails, the screen is sent back — you only ever see verified output.
