World Usability Day 2026: ethical AI has to be accessible AI

Today is World Usability Day, and this year’s theme is Designing a Sustainable Future with Ethical AI. The organizers describe a future where human creativity and AI work together to support diverse communities, protect the planet, and widen equitable access to knowledge.

We like that picture a lot. We also know what it takes for AI to live up to it, because we spend our days looking at what AI produces on real websites. Alt text that describes an image without explaining why it’s there. Generated components that skip keyboard support. Chat windows that screen readers can’t follow.

Here’s where this year’s theme meets accessibility work, and where you can keep the conversation going with our team.

Ethical AI starts with who can use it

The theme’s first question is how to design AI that respects human rights and cultural diversity. For people with disabilities, that respect gets tested in very practical ways. Can a screen reader user follow the chatbot’s answer? Can a keyboard user reach every control the AI generated? Does the alt text tell you why the image is on the page, or just what’s in it?

Heather Berg, Certified Professional in Accessibility Core Competencies (CPACC), Digital Equity Specialist, and Gianna Barnhart, Sales Manager, took on those questions in our webinar, Is AI making the web less accessible? New challenges from AI-generated content. They covered where AI is creating new barriers and where it genuinely helps, including:

• Where AI-generated code tends to introduce accessibility issues, and what to check before it ships
• The limits of AI-generated alt text and captions
• Why AI-powered overlays don’t make a site accessible, no matter how they’re marketed
• Where AI can support accessibility work, as long as a person reviews the results

That last point is the thread running through all of it. AI can speed up the work. People still have to check it.

Access to knowledge depends on accessible pages

World Usability Day pictures AI as a way to connect communities, widen access to knowledge, and reduce digital inequality. Most of that knowledge lives on the web, and most of the web still has barriers.

WebAIM’s 2026 Million report found that 95.9% of home pages had at least one detectable Web Content Accessibility Guidelines (WCAG) 2.x failure, up from 94.8% the year before. WebAIM names AI-assisted coding as one likely factor. If AI helps us publish faster without helping us publish better, people with disabilities get left further behind.

Sustainable means built to last

The theme talks about sustainability in terms of energy, economies, and cities. On the web, a sustainable approach is one that keeps working as your site changes. Accessibility is ongoing: content gets added, designs get refreshed, and AI tools generate new code every day.

Overlays are the opposite. They sit on top of a site and promise a fix without touching the barriers underneath. A sustainable approach builds accessibility into how you design, code, and review, then keeps checking.

Overlays are the opposite. They sit on top of a site and promise a fix without touching the barriers underneath, and they can create new barriers for people using their own assistive technology. A sustainable approach builds accessibility into how you design, code, and review, then keeps checking.

Already using an overlay? In our webinar How to replace your accessibility overlay, Kelsie Cleboski, Certified Professional in Web Accessibility (CPWA), Senior Digital Accessibility Specialist, covers the legal and user experience risks of relying on one, how to plan the transition, and which accessibility issues to tackle first so you can remove it with confidence.

A sustainable approach is also the thinking behind Accessible Web RAMP. RAMP helps your team find accessibility violations, understand them, organize remediation tasks, and track the work over time. Automated page monitoring, the Accessible Web Helper Chrome extension, and the Compliance Center all live in one place. With RAMP, organizations can go beyond compliance and create sustainable, accessible digital experiences that evolve with users’ needs.

Many perspectives, including disability

The theme’s last dimension asks for AI ethics that reflect many perspectives rather than a single framework. Disability is part of that diversity. AI trained toward one default user will miss the ways people of all abilities actually use the web.

Human review, testing with assistive technology, and listening to people with disabilities are how you catch what a model’s defaults leave out. Not shortcuts.

Keep the conversation going at our next AI webinars

We’re spending the rest of the year on AI and accessibility, and both sessions are open to anyone building, managing, or reviewing a website.

Vibe coded and inaccessible? What AI-built sites get wrong

Thursday, November 19 at 2:00 PM EST

AI can now build a working website from a single prompt, an approach often called vibe coding. Whether that site works for screen reader users and keyboard users is a different question. Shannon O’Connor, AI Contractor at Accessible Web, follows up on our earlier session with a closer look at how common vibe coding has become

Shannon will walk through WebAIM data on growing page complexity and findings from the AIMAC report on how different AI models perform on accessibility. Simpler models tended to produce more accessible pages. You’ll also hear whether adding accessibility guidance to your prompts actually improves the code you get back, and practical ways to protect accessibility in vibe coded sites, starting with keeping things simple.

AI-powered assistive technology

Thursday, December 17 at 2:00 PM EST

AI is changing the tools people with disabilities use to get around the web. Image descriptions can fill in where alt text is missing, live captioning can follow a conversation as it happens, and voice tools can handle tasks that used to take many steps.

Heather Berg, CPACC, will look at where these tools stand today, how people with disabilities are using them, and where they fall short. She’ll also cover what they mean for anyone who builds or manages a website. Spoiler: they don’t replace an accessible site.

Curious about a specific tool, or building with AI yourself? Bring your questions to either session. We encourage you to ask them live!

Celebrate World Usability Day with one small test

Using AI to write code this week? Before it ships, tab through it with your keyboard and listen to it with a screen reader. You’ll learn a lot about how ethical your AI really is.
