I have seen AI-generated interfaces that look spectacular. Vibrant colors, modern layouts, typefaces that seem chosen by an art director with twenty years of experience. And most of them do not pass a basic WCAG contrast test.
That is the problem with AI and accessibility. AI optimizes for what looks good not for what works for everyone.
What AI generates and what it ignores
When you ask an AI to generate an interface it does not think about the user who needs a screen reader. It does not consider that the light gray text on white background that looks so elegant is unreadable for someone with low vision. It does not know that buttons need a minimum touch target for people with reduced mobility. It does not understand that a navigation flow that depends only on color excludes eight percent of the male population that is colorblind.
AI generates what is aesthetically optimal. Accessibility requires what is functionally inclusive. And those two things are sometimes in direct tension.
Where AI does help with accessibility
Not everything is negative. AI is excellent at auditing accessibility quickly. I pass a design to Claude and ask it to check for contrast issues, minimum text sizes, heading hierarchy and missing ARIA labels. On a project for a financial company I found twelve accessibility problems I had overlooked simply because I had been looking at the same screens for weeks and my eye had gotten used to them.
It is also good at generating alt text for images. Describing an image concisely and usefully for a screen reader is a task AI does surprisingly well, much better than the generic alt text most developers add out of obligation.
Accessibility as the human designer's advantage
There is something important here. In a world where AI generates interfaces faster and faster, accessibility becomes one of the clearest differentiators between a designer who knows what they are doing and a machine that only generates what looks pretty.
Because accessibility is not a checklist. It is systematized empathy. It is understanding that you design for people with different abilities in different contexts using different devices. That requires a level of human understanding that AI simply does not have.
If you are a designer and do not yet master WCAG, now is the best time to learn it. Not only because it is the right thing to do but because it is what will make you indispensable when AI can generate everything else.
Accessibility is the last bastion of design that no machine will solve alone. And that should matter to us.
