What is AI Accessibility Testing
AI accessibility testing is shaking up how we make sure digital content works for everyone, including people with disabilities. It's a smart combo of AI and traditional testing methods that's creating more inclusive digital experiences.
Main Ideas and Rules
AI accessibility testing uses machine learning to automatically spot potential accessibility issues in websites, apps, and other digital products. It's faster than manual testing and can catch problems humans might miss.
Here's what makes AI accessibility testing tick:
- It's quick. AI tools can scan entire websites or apps in no time.
- It's always on. Unlike manual testing, AI can keep an eye on things 24/7.
- It's scalable. AI can handle big, complex applications better than humans alone.
- It's consistent. AI applies the same rules every time, reducing human error.
But here's the thing: AI accessibility testing isn't perfect. Robin Christopherson, MBE, Head of Digital Inclusion at AbilityNet, puts it this way:
"For the foreseeable future, any accessibility checker - even though it leverages the power of cutting-edge AI - will only ever be able to do a partial job of testing a website or app for compliance."
So, the best approach? Use AI testing alongside human expertise.
How AI Works in Testing
AI accessibility testing uses some pretty cool tech to analyze digital content:
- It uses Natural Language Processing to check if text is easy to understand.
- It uses Computer Vision to look at images and videos, making sure they're described well for visually impaired users.
- It learns from tons of data about accessibility issues, getting better over time.
- It spots patterns in code and design that might cause accessibility problems.
For example, an AI tool might scan a website and notice some images don't have alt text. It'll flag these issues and might even suggest descriptions based on what's in the image.
Dekel Skoop, CEO and Co-Founder of accessiBe, says:
"AI is revolutionizing web accessibility, offering a more affordable automated solution that can do much of the heavy lifting required to make the internet a more inclusive space."
But remember, AI can't fully replicate the human experience of using a website or app. That's why a mix of AI tools and manual testing is often the way to go.
Using AI in accessibility testing helps businesses:
- Find about 30% of accessibility issues quickly and reliably
- Cut down on time and money spent on manual testing
- Stay compliant as websites and apps change
- Make things better for users with disabilities
As the digital world gets more complex, AI accessibility testing is becoming a must-have tool for creating inclusive online experiences. It's not a complete replacement for human know-how, but it's a powerful ally in making the digital world accessible to everyone.
AI Testing Tools You Can Use
AI-powered accessibility testing tools are changing how we make digital content usable for everyone. These smart helpers quickly spot issues that might make websites or apps hard for people with disabilities to use.
Testing Systems and Software
Here are some top AI accessibility testing tools making a big impact:
axe: Available as a browser extension and npm package, axe is free (with a paid version for extra features) and supports WCAG 2.1 standards. It helps with manual tests and can be customized with plugins. The latest release was on May 8, 2024.
Lighthouse: Built into Google Chrome, Lighthouse is free, supports WCAG 2.1, and works for both automated and manual testing. It's customizable and fits well in continuous integration setups.
WAVE: Offering a browser extension, web app, and API, WAVE supports the latest WCAG 2.2 standards. It's user-friendly and gives visual feedback on accessibility issues right in your browser. As WebAIM, the creators of WAVE, says:
"WAVE injects visual indicators into your web page to highlight accessibility issues, such as missing alt text, improper heading structures, and low contrast ratios."
This visual approach helps developers understand and fix problems more easily.
These tools are great, but they're not perfect. A study by Equal Entry found that even the best automated tools only caught between 3.8% to 10.6% of accessibility issues in a test website. This shows why it's important to use AI tools alongside human expertise.
For better results, try using a mix of tools. You could use axe for detailed reports, Lighthouse for quick checks during development, and WAVE for visual feedback. This strategy can help catch more issues.
Remember, the goal isn't just to pass an automated test. It's about making digital experiences that everyone can use. Robin Christopherson, Head of Digital Inclusion at AbilityNet, puts it well:
"For the foreseeable future, any accessibility checker - even though it leverages the power of cutting-edge AI - will only ever be able to do a partial job of testing a website or app for compliance."
So, while AI tools are super helpful, they work best as part of a bigger plan that includes manual testing and, ideally, feedback from users with disabilities.
How to Start Using AI Testing
Let's dive into how you can start using AI for accessibility testing. It's not as complex as you might think.
Adding AI to Your Work Process
Here's how to get AI accessibility testing into your development cycle:
1. Pick your tools
Start with popular options like axe, Lighthouse, or WAVE. Each has its own strengths, so choose what fits your needs best.
2. Set up automated testing
Get your AI tool working with your CI/CD pipeline. This way, accessibility checks happen automatically when you push new code.
3. Define your standards
Stick to WCAG 2.1 Level AA. It's the industry standard for accessibility.
4. Train your team
Make sure everyone knows why accessibility matters and how to use the AI tools.
5. Run regular scans
Schedule full-site scans to catch any sneaky issues.
Take BrowserStack, for example. They offer accessibility testing for iOS and Android apps, both manual and automated. Their system watches for DOM changes and kicks off accessibility scans automatically. It's a great way to catch issues early.
Checking Test Results
AI tools are smart, but they're not perfect. Here's how to get the most out of your results:
1. Review the reports
Go through the issues your AI tool flags. Some might be false alarms or need more context.
2. Prioritize
Focus on the big stuff first, like keyboard navigation problems or missing alt text for images.
3. Mix in manual testing
Use AI results as a starting point, then follow up with manual checks. As Robin Christopherson from AbilityNet says:
"For the foreseeable future, any accessibility checker - even though it leverages the power of cutting-edge AI - will only ever be able to do a partial job of testing a website or app for compliance."
4. Get diverse testers
Include people with various disabilities in your testing. They'll give you real-world feedback you can't get from AI alone.
5. Use multiple tools
Different AI tools catch different issues. Try using a mix, like axe for detailed reports and WAVE for visual feedback.

Latest Testing Methods
AI is changing the game in accessibility testing. It's making things faster, more accurate, and even fixing issues on its own. Let's dive into some new methods that are shaking things up.
24/7 Testing Systems
Non-stop monitoring is becoming the new normal. AI tools now watch websites and apps around the clock, making sure they stay accessible even when content changes.
Take UserWay, for example. They offer constant monitoring to keep things in line with standards like WCAG. Their AI system is always on the lookout for issues, so developers can spot and fix problems fast.
Max Access takes it a step further. Their automated system checks websites daily, looking at new content and fixing accessibility issues within 24 hours. It's like having a tireless accessibility expert on your team.
BrowserStack is doing something cool too. They've baked accessibility testing right into the development process. Their system watches for changes and kicks off scans automatically. It's all about catching problems early.
Auto-Fix Features
Now, here's where things get really interesting. Some AI tools don't just find problems - they fix them too.
AccessiBe is leading the charge here. Their AI can fix a bunch of accessibility issues on its own. It can write alt text for images, tweak color contrasts, and even rejig website structure to make it easier for screen readers.
AudioEye is another big player. Their system can spot and fix up to 50% of common issues in real-time. As Kelly J., who uses AudioEye, puts it:
"AudioEye gives me peace of mind that our site accessibility issues are being addressed."
This auto-fix stuff is a game-changer, especially if you're short on accessibility experts.
But here's the thing: these AI tools are great, but they're not perfect. Robin Christopherson from AbilityNet says:
"For the foreseeable future, any accessibility checker - even though it leverages the power of cutting-edge AI - will only ever be able to do a partial job of testing a website or app for compliance."
So, while AI is awesome, it's best to pair it with human know-how for the best results.
Want to make the most of these new testing methods? Here's what to do:
- Get a continuous monitoring tool to catch issues fast.
- Use auto-fix features for common problems.
- Double-check AI fixes to make sure they work for you.
- Mix AI testing with manual checks and real user testing.
What AI Can't Do Yet
AI has changed the game for accessibility testing. But it's not perfect. There are still areas where humans do it better. Let's look at where AI falls short and when you need real people.
When Human Testing Wins
AI tools are great, but they can't match human understanding. Here's why we still need human testers:
1. Context is King
AI doesn't get context. It might flag a logo for bad contrast, not knowing logos get a pass. Humans can apply WCAG rules with more flexibility.
2. It's Not All Black and White
AI can't judge if something is clear, understandable, or culturally appropriate. Frank Spillers, CEO of Experience Dynamics, puts it well:
"Automated evaluation alone cannot determine accessibility."
Human testers bring empathy and cultural know-how to the table.
3. Tech Compatibility
AI struggles to mimic how assistive tech works with websites. Real users with disabilities offer insights AI can't match.
4. Complex User Journeys
AI can check if keyboard navigation exists, but it can't tell if it makes sense. Humans can spot frustrating user experiences that AI misses.
5. Alt Text Quality
AI can see if images have alt text, but it can't judge if that text actually helps. This needs a human touch.
The numbers back this up:
- Equal Entry found automated tools catch only 20-30% of accessibility issues.
- Even the best AI checker only covers 57% of problems, says Deque.
So, how do we fill this gap? Try this:
- Start with AI tools like axe or WAVE for a quick scan.
- Follow up with expert manual checks.
- Test with users who have disabilities (WCAG 3.0 will require this).
- Mix automated tools, expert reviews, and user testing.
- Keep checking regularly - accessibility isn't a one-and-done deal.
Kami Funk, an accessibility pro, sums it up:
"AI is just that - artificial. It does not have the human ability to differentiate things that are and aren't accessible, which can sometimes cause issues."
Human insight is still key in making the web work for everyone.
AI vs. Manual Testing: Side by Side
AI and manual testing both play crucial roles in accessibility testing. Let's see how they compare:
| Aspect | AI Testing | Manual Testing |
|---|---|---|
| Speed | Lightning-fast, scanning thousands of pages in minutes | Slower, but thorough |
| Accuracy | 30-40% accuracy rate | Catches nuanced issues |
| Cost | Cost-effective for large projects | Higher due to human labor |
| Scope | Limited to detectable issues | Comprehensive, including UX |
| Context | Can't interpret context | Assesses relevance and appropriateness |
| Consistency | Consistent results across scans | May vary with tester's expertise |
| User Experience | Can't replicate real interactions | Provides real user insights |
AI testing is quick and consistent, but manual testing brings the human touch. As Frank Spillers, CEO of Experience Dynamics, puts it:
"Automated evaluation alone cannot determine accessibility."
This highlights why human judgment is key in accessibility testing.
AI tools like axe and WAVE excel at finding technical issues:
- Missing alt text
- Bad heading structures
- Color contrast problems
- Missing form labels
They're great for a quick compliance check.
But human testers shine when evaluating:
- Content clarity
- Navigation flow
- Alt text quality
- Overall user experience
Manual testing digs deeper into how real users interact with your site.
The best strategy? Use both. Start with AI for a quick scan, then follow up with manual testing. This combo helps you catch obvious and subtle issues alike.
Take BrowserStack, for example. They've baked accessibility testing into their dev process. Their system auto-scans when changes happen, helping devs catch and fix issues early.
Conclusion
AI accessibility testing is changing the game for digital inclusivity. It's not just about ticking boxes - it's about making the web better for everyone.
Here's what you need to know:
AI tools like axe and WAVE can scan thousands of pages in no time. They catch basic issues like missing alt text and poor color contrast. This is huge for big, complex websites.
But AI isn't perfect. It catches about 30-40% of accessibility issues. That might not sound like much, but it's a big time-saver. As Frank Spillers from Experience Dynamics puts it:
"Automated evaluation alone cannot determine accessibility."
This is why we still need humans in the mix.
The legal stuff? It's serious. ADA-related lawsuits are on the rise. First-time violations can cost $75,000, and repeat offenses can hit $150,000.
AI is getting better, though. Companies like AccessiBe and AudioEye are pushing the envelope. Their AI can now fix common issues on its own, like writing alt text and tweaking color contrasts.
The future? It's a team effort between AI and humans. Start with AI scans, then bring in the experts and real users with disabilities.
Want to make the most of AI in accessibility testing? Here's how:
1. Start early: Make AI testing part of your development process from the get-go.
2. Mix it up: Use different AI tools to catch more issues.
3. Keep it human: AI can't replace real user experiences. Include testers with disabilities.
4. Stay sharp: Keep your AI tools and knowledge up-to-date.
5. Aim high: Don't just comply - create truly inclusive experiences.
Robin Christopherson from AbilityNet nails it:
"For the foreseeable future, any accessibility checker - even though it leverages the power of cutting-edge AI - will only ever be able to do a partial job of testing a website or app for compliance."
AI is a powerful tool for web accessibility, but it's not the whole story. Use it wisely, and always think about the end user. By combining AI's speed with human know-how, we can make the digital world work better for everyone.
FAQs
How does AI benefit accessibility?
AI is changing the game for accessibility testing. Here's how:
Automatic alt text: AI can whip up alt text for images and videos on websites. This is huge for screen reader users. Eric Eggert, a Web Accessibility Pro, says:
"AI can automatically create alt texts for images and videos, quickly providing alternative text descriptions for websites. This makes websites more accessible for screen readers to help interpret the image and explain to the person behind the screen what is being shown on-screen."
Speedy issue spotting: AI tools zip through code, flagging accessibility problems like missing alt text or wonky color contrasts. This quick catch helps developers fix issues early on.
Always-on monitoring: AI keeps an eye on things 24/7, making sure websites stay accessible even when content changes. BrowserStack, for example, has baked AI accessibility testing right into their development pipeline.
Budget-friendly compliance: AI makes thorough accessibility testing doable for businesses with big, complex websites. It can scan thousands of pages in a flash - something that'd be a nightmare to do by hand.
But remember, AI isn't the whole story. Trenton Moss, a usability expert at Webcredible, advises:
"AI is a powerful tool, but it should be used in conjunction with manual testing and real user feedback for the best results in achieving true accessibility."
AI's great, but it's not perfect. It's one tool in the accessibility toolkit, not the entire workshop.
