Hand Claude one hypothesis, read access to your Figma file, and your brand styles. It gives you back a built variant, an annotated rationale, a QA pass, and paste-ready variant code. Hypothesis to dev-ready in 15 to 25 minutes per variant.
Design is the bottleneck on most testing programs. You write a brief, wait three days for the designer, review, send it back, wait again. By the time the variant is ready the campaign moved. This is the workflow that takes design off the critical path so your store can ship 4 to 8 tests a month without the wait.
The common misread is that AI replaces designers. It doesn't. Claude designs the way a fast, literal product designer designs. It reads what is in front of it, stays inside your system, and will not invent a layout that has never existed in your file.
That is the exact shape of A/B testing. In a test you are rarely inventing. You vary one or two elements against a control. Move the badge. Rewrite the CTA. Reorder the sections. Controlled change is precisely the work Claude handles well:
Your designer still earns the small fraction of tests that need a brand-new visual pattern: a quiz module on a store that never had one, a homepage hero swap during a campaign, anything touching the brand expression itself (logo, type system, palette). For copy swaps, layout reorders, social-proof repositioning, CTA experiments, hierarchy tweaks, and mobile fit-ups, Claude does it.
<aside> ✅
Steal this: Pull your last 10 shipped tests. Tag each one "controlled change" or "new pattern." Everything in the first bucket is work this workflow does tomorrow. That count is how many design days a month you are about to get back.

| Step | What | Time |
|---|---|---|
| 1 | Install Figma's official MCP (one line, Dev or Full seat) | one-time |
| 2 | Import your live page into Figma with html.to.design (mobile + desktop) | one-time per surface |
| 3 | Set up a Variants page and a clean component library | one-time |
| 4 | Run the five-prompt design sequence (brief, variant, annotate, QA, code) | 15 to 25 min |
| 5 | You or your strategist sign off | 5 to 10 min |
| 6 | Hand the code + frame to dev, or paste it straight into your testing platform | minutes |
Cost beyond your Claude usage: zero.
