Claude Design — and the question it raises about design agencies
25 April 2026 · Design & Branding
This week Anthropic released Claude Design — a dedicated design surface inside Claude.ai for building UI prototypes, design systems, and visual assets the way you already build everything else with Claude: by talking to it.
I've spent the week using it. It's genuinely impressive, and it's already shifting how I think about where design work happens — and where design agencies should be focusing their energy from here on.
What Claude Design actually is
Claude Design lives at claude.ai/design and is available on the paid Claude tiers — you'll need to be on a Pro plan or above to use it. Free users won't see it.
The medium it works in is interesting: it doesn't generate Figma files or Sketch documents. It produces HTML, CSS, and JavaScript prototypes. That sounds like a small detail, but it's the whole point. The output is something a coding agent can read directly. There's no translation step from "designer file" to "developer file" — the design is the spec.
When you're done, you can export the project as a handoff bundle. The bundle drops into a coding agent (Claude Code, Cursor, anything that can read files) with a README.md that says, in effect: here are the prototypes, here's the design system, here's the asset kit — go build it for real.
That's the shape of the tool. The bigger story is what it enables.
What you can now do yourself
Three things have just become genuinely doable for someone working solo or in a small team:
Design systems from your existing codebase. Point Claude Design at what you've already built and it will derive a coherent system from it — colours, type, spacing, components, states. Not a guess at what your brand could be, but a structured account of what it already is, ready to be refined.
UI refinement and onboarding flair. Functional UIs that work but feel flat are everywhere. Claude Design is unusually good at the layer above functional — the layer that makes a product feel cared for. Illustrations, micro-interactions, the small moments that turn a screen into an experience.
Brand consistency across surfaces. Once a system exists, applying it everywhere becomes a tractable problem rather than an expensive coordination exercise. The same tokens, the same characters, the same voice — across web, app, portal, customer-facing material.
What I've used it for so far
An app I've been building
I had a working iOS app with an onboarding flow that did its job and nothing more. Functional. Forgettable. I worked with Claude Design to derive a design system from the existing codebase, then iterated on the onboarding experience together — refining the visual language, building out illustrations, and animating characters into the flow.
What's emerging is much richer: a consistent visual world, characters with personality, those small moments of magic that surprise and delight users when they weren't expecting it. The kind of thing that used to require a dedicated illustrator, an animator, and weeks of agency time.
This website
The site you're reading was built with Claude Code. This week I turned Claude Design loose on it and asked it to derive a design system from what was already there. It picked up the existing branding immediately — the warm off-white canvas, the Claude Orange accent, the Outfit typography, the bot characters. Nothing invented; everything observed.
From there we worked together to extend it. Complementary colour schemes for places the original palette was thin. A proper warm RAG palette — #C4514B / #D4913A / #5A9E6F — desaturated to sit alongside the warm neutrals without screaming. And then the part I enjoyed most: an extended cast of characters representing different teams within a business and the various ITIL functions you'd find in an IT organisation. Concepts that used to need a paragraph of explanation can now be drawn.
The full system is now packaged as a handoff bundle — a folder a coding agent can read, with colors_and_type.css tokens, preview cards, and pixel-faithful HTML recreations of the live pages.
Next: an employer brand refresh
The brand at the company I work for hasn't had a refresh in years. The website, customer-facing material, and portal systems all look like they're from the same company if you squint, but the consistency is held together by habit rather than design. There's no shared system underneath any of it.
That's the problem Claude Design seems built for. I'll be using it to derive what's actually there, propose a coherent system across all the touchpoints, and produce the handoff material to roll it out. I'll write that one up properly when it's done.
So — what about design agencies?
This is the question worth taking seriously. If a tool like this can produce a design system, refine UI, generate illustrations, and package the whole thing for engineering — what's left for a design agency to do?
A lot, actually. But it's a different "lot" than it used to be.
What's moving in-house:
- Mid-tier execution — design system derivation, UI refinement, component libraries, illustration work, applying an existing brand to a new surface
- Iteration speed — twenty rounds of "what about this version?" no longer requires twenty agency hours
- Maintenance — keeping a system up to date as a product evolves
What an agency still does better than you:
- Brand strategy from a blank page. When you don't know what you stand for yet, AI can't tell you. The work of figuring out who you are — through workshops, customer research, market analysis — is still a deeply human craft.
- Original brand identity. Claude Design is excellent at deriving a system from what exists. It's less suited to inventing a visual world from nothing — to deciding that should be the colour, those should be the shapes, this should be the feeling. That's where a good agency earns its fee.
- Deep user research. Generative testing, ethnographic studies, the slow careful work of understanding what your users actually need — not what they say they need.
- Taste at scale. AI gets you 85% of the way there fast. The last 15% — the difference between competent and memorable — still benefits enormously from someone who has spent twenty years looking at design and can tell you why something isn't working.
- Accountability. When the brand has to land in front of a board, an investor, or a regulator, the agency is the one with their name on it. That matters.
The honest summary: agencies should stop selling the middle of the curve. The middle has been collapsing into AI tools for two years and Claude Design is the clearest example yet. The top and the bottom — strategy and original identity at one end, applied execution at the other — are where the value is. Smart agencies are already moving there.
Where to focus external support
If you're spending money with a design agency right now, here's the honest test I'd apply:
- Is this work helping me figure out who we are? → Keep paying for it. AI can't do this for you.
- Is this work producing a foundational visual identity from scratch? → Keep paying for it.
- Is this work applying an existing system to new surfaces? → You can probably do this yourself with Claude Design.
- Is this work iterating on a UI that's already mostly right? → Almost certainly in-house now.
- Is this work producing a design system from an existing product? → Definitely in-house.
The instinct to outsource the whole stack to an agency made sense when the cost of design tooling was high and the cost of designer time was even higher. Both numbers have changed. The shape of the relationship should change with them.
The pattern I keep seeing
This is the same shape as everything else AI is doing right now. The middle of the skill curve compresses. The top of the curve — judgement, taste, strategy, accountability — gets more valuable, not less. The bottom of the curve — applied execution that used to require a specialist — moves toward generalists with good tooling.
Claude Design is just the design version of that pattern.
If you've been waiting for a sign that it's worth taking AI-assisted design seriously, this is it. Spin up a Pro plan, point it at your existing product, and see what comes back. Then have an honest conversation about where your agency budget should actually go.
