Can AI Help Make Websites More Accessible?

AI-powered accessibility tools promise to make websites more inclusive without the need for extensive manual remediation. Some of these tools genuinely help. Others create a false sense of compliance. Understanding the difference matters.

The accessibility overlay industry has grown rapidly, with tools like AccessiBe, UserWay, and AudioEye claiming to fix accessibility issues automatically. But the reality is more nuanced than the marketing suggests.

What AI Accessibility Tools Actually Do

• Automated alt text generation for images using computer vision
• Text-to-speech functionality for visitors with visual impairments
• Colour contrast adjustment tools
• Font size and spacing controls
• Keyboard navigation enhancements
• Screen reader compatibility improvements
• Automated WCAG compliance scanning

What Works and What Doesn't

The Overlay Problem

Accessibility overlays — those toolbar widgets you see on some websites — have been widely criticised by the accessibility community. Many disability advocacy organisations have publicly opposed them.

• Overlays can interfere with screen readers that users already have configured
• They often don't fix underlying HTML and structural issues
• They can create a false sense of WCAG compliance
• Some overlays have actually been named in accessibility lawsuits
• The National Federation of the Blind has spoken against certain overlay solutions

Where AI Genuinely Helps

Despite the overlay controversy, AI does have genuine applications in accessibility. The key is using AI as a tool within a broader accessibility strategy, not as a standalone fix.

• Automated testing to identify issues (complementing manual testing, not replacing it)
• Generating initial alt text that humans then review and refine
• Monitoring for new accessibility issues as content changes
• Analysing colour contrast across entire sites quickly
• Identifying missing form labels and ARIA attributes
• Tracking compliance status across large sites

A Better Approach to Accessibility

1. Build accessibility into your design and development process from the start
2. Use AI tools for scanning and monitoring, not as the primary fix
3. Conduct manual testing with assistive technologies
4. Include people with disabilities in user testing where possible
5. Train your content team on accessible content creation

Legal Considerations for Ireland

Irish websites are subject to equality legislation and the EU Web Accessibility Directive (for public sector). Using an overlay tool does not constitute legal compliance. The Irish Human Rights and Equality Commission can investigate accessibility complaints.

The European Union's approach to digital accessibility has become increasingly stringent. The EU Web Accessibility Directive, implemented in Ireland through the Disability Act, requires public sector websites to meet WCAG 2.1 AA standards. The DPC Ireland (Data Protection Commission) has also begun examining accessibility as part of broader digital rights compliance. For Irish businesses operating online, accessibility isn't optional—it's a legal and ethical requirement. Many Irish organisations have faced complaints and demands for remediation when they've relied solely on overlay solutions. The solution that regulatory bodies like the Irish Human Rights and Equality Commission expect is genuine, built-in accessibility.

Implementation Strategies for Irish Websites

Irish website owners have found success with structured accessibility strategies. Start with a WCAG 2.1 AA audit to identify real issues. Work with accessibility consultants (many are based in Ireland) to fix structural problems. Use AI tools to monitor and test, but treat the results as a starting point. Train your team on accessible content creation—this ongoing effort prevents new issues. Document your accessibility statement and remediation efforts, as these demonstrate good faith compliance to regulators and users. Regular testing with real screen readers and user feedback from people with disabilities ensures your improvements actually work.

The Role of Anthropic and Modern AI in Accessibility

Leading AI research organisations, including Anthropic, are increasingly focusing on accessibility in AI systems themselves. This reflects a broader industry shift toward building inclusive technology from the foundation. When evaluating AI accessibility tools, look for products built by companies committed to accessibility principles throughout their operations, not just those selling an overlay solution.
