Turn your coding agent into the ultimate designer
Build UIs that need no explanation, ship faster, and burn fewer tokens.
“I'm stuck with prototype-level design.”
You asked Claude to build a settings page. It shipped in 2 minutes. But it's unusable for serious projects. The UX is unintuitive. Your brand colors? Nowhere. Error states? Missing. Mobile layout? A mess.
Where your coding agent meets its design team
Design Rails pairs your coding agent with specialized AI counterparts, each with deep context of your brand and a unique design domain expertise. They work in parallel to generate comprehensive specs for your coding agent to implement, and to review your agent's implementation.
Specialist agent team
Copywriters, UX designers, visual designers, and accessibility experts work in parallel to craft each interface.
Deep product and brand knowledge
Deep context of your users, workflows, component library, brand guidelines, and design system, so every spec is tailored to your product.
Proven UX patterns
A growing library of proven UX patterns featured in top products, ready for agents to reference when solving design challenges.

From feature request to polished design
You describe the feature
Tell your coding agent what you want to build, just like you normally would.
Design Rails assembles the team
Your coding agent calls Design Rails, which orchestrates specialist AI agents with deep knowledge of your product and brand.
Specialists work in parallel
Copywriters craft messaging, UX designers plan workflows and interactions, visual designers apply your brand, accessibility experts ensure compliance. Each contributes their expertise simultaneously.
A comprehensive spec emerges
Complete with layout decisions, component choices, responsive behavior, copy that matches your voice, edge cases, error states, loading states, and accessibility considerations.
Your coding agent implements it
With a detailed design blueprint in hand, your coding agent writes production-ready code confidently.
What you get with Design Rails
Maintain consistency across your product
No more franken-UI. Design Rails ensures every new component respects your design system, follows established patterns, and maintains brand coherence.
Use proven patterns, not generic defaults
Access to battle-tested patterns from industry leaders means your AI agent taps into collective design wisdom, not just generic Material UI components.
Cover edge cases that always get forgotten
Empty states. Error messages. Loading indicators. Mobile layouts. The unglamorous-but-essential details that separate amateur from professional UI.
Extend designer thinking through every commit
When designers define your system, patterns, and standards, Design Rails ensures those decisions get applied correctly every time. This frees them to work on novel UX problems, user research, and strategic improvements instead of repetitive component decisions.
