Questions, answered
What is Specimen Design?
A free library of full website designs. Every design runs live in your browser and comes with a detailed prompt you can paste into Claude to build it. Single UI components live separately, in the components lab.
How do I use a Claude prompt to design a website?
Open any design, press “Copy Claude Prompt” and paste it into Claude. You get a complete React component with Tailwind CSS and Framer Motion that you can drop into a Next.js site.
Are the designs free to use?
Yes. All designs and code are free to use in personal and commercial projects under the MIT license.
How do I make an AI-built website not look AI-generated?
Start from a clear design language instead of defaults: a deliberate typeface pairing, a strict palette with one accent, and motion with real spring physics. Every prompt here spells those choices out.
Which design styles are included?
28 design languages, including Neo-Brutalist, Bauhaus, Swiss, Japanese Minimal, Luxury Noir, Retro 70s, Memphis, Y2K, Claymorphism, Risograph, Art Deco and 8-bit.
