Per-token anxiety is over. Build on your own GPU.

Two AI models. One self-healing pipeline. Zero API credits for execution. Your local GPU does the heavy lifting — Opus makes sure it doesn't hallucinate.

Begin the Mission

Two specialists. One mission.

One model thinks. The other builds. They never swap roles. That's the entire trick.

THE BRAIN

Claude Opus 4.6 Extended

Reads your prompt and every reference. Extracts typography, spacing, color, layout patterns. Writes a structured Design DNA blueprint — not code. Never writes a single line of HTML.

THE HANDS

Local Qwen3-Coder 30B

Runs on your GPU at 220 tokens/second. Takes the Design DNA and builds production HTML, section by section. If a section fails validation, it retries — no human input, no extra cost.

Cloud cost: $1.01 architecture · Local cost: $0.00 execution · Total: $1.01

From prompt to deployed site. One take.

Watch the full workflow — prompt crafting, reference attachment, Design DNA extraction, smart-routed build, inline editing, and accessibility repair. Total cost: $1.01.

You don't fly blind. You fly with instruments.

AI gets you 80% there. The property panel handles the last 20%. You're the pilot, not a passenger.

Inspect any element. See its exact CSS.

Property panel — font, color, spacing, live.

Select it. Delete key. It's gone.

WCAG contrast checker. One click auto-fix.

See it. Click it. Ship it.

No description needed. Watch the tools work.

Click any text. Change it. The DOM, source, and preview update instantly.
Every build step is a checkpoint. Side-by-side diff. Cherry-pick any section.
One-click WCAG contrast scan. Failing colors auto-adjusted to pass AA.

Everything under the hood.

ASYMMETRIC PIPELINE

Opus thinks, local GPU builds

Architecture and execution are split across two models. You pay for intelligence, not keystrokes.

DESIGN DNA

Reference-driven blueprints

Attach any screenshot or URL. Opus extracts typography, spacing, and color into a structured spec.

EDIT IN PLACE

Click and change anything

Select text, adjust properties, delete elements. Changes sync to source and preview in real time.

WCAG AUTO-FIX

Accessibility in one click

Scan every text element for contrast ratio. Failing colors are auto-adjusted to meet AA standards.

VERSION HISTORY

Every step is a checkpoint

Side-by-side diff for every build step. Roll back to any version or cherry-pick individual sections.

EXPORT TO ZIP

Your code, your server

One click. Clean HTML file. No vendor lock-in. Deploy to Vercel, Netlify, or your own server.

Same AI. Different input.

You shouldn't rent your tools.

Every AI coding tool today charges per generation. Your creativity becomes metered. Cozonac flips the model — use the cloud for the hard part, your own hardware for everything else. The result: professional sites for under a dollar.
