Human-centered AI
How AI Can Improve Accessibility
AI can help make information easier to access by supporting captions, summaries, alternative text, translation, and simpler explanations.
Accessibility is about reducing barriers
People access information in different ways. Some need captions, screen reader support, simpler language, translation, or help navigating long documents. AI can support these needs when it is used carefully and checked by people.
Reader value
Accessibility improves when AI supports good design
AI can help create captions, summaries, alternative text, translation drafts, and simpler explanations. These supports can make information easier to reach for more people when they are reviewed carefully.
AI is not a substitute for accessible design. Pages still need readable text, good contrast, keyboard navigation, meaningful headings, and forms that work for assistive technology.
Use it for
- Drafting alt text that a person reviews.
- Turning complex instructions into simpler wording.
- Creating transcript or caption drafts for media.
Check before relying on it
- Does the description include the information users need?
- Did a person review errors or missing context?
- Does the page itself work without a mouse?
Plain-English example
A website owner can ask AI to draft alt text for product images, then review whether each description includes the information a blind shopper would need. ?Image of product? is not enough if color, size, or function matters.
AI can speed up the draft, but accessibility depends on the reviewer understanding what users need from the page.
Try this next
Pick one page and ask AI to identify where readers might struggle: complex sentences, missing headings, unclear link text, or images without useful descriptions. Use the answer as a checklist, not a final audit.
After that, test the page yourself with keyboard navigation and simple reading. Accessibility is confirmed through use, not only through generated suggestions.
Helpful examples
- Drafting captions or transcripts for audio and video.
- Generating alternative text for images that a person reviews.
- Summarizing long documents into plain language.
- Translating basic information for wider understanding.
- Reformatting information into checklists or step-by-step instructions.
Human review still matters
Accessibility mistakes can exclude people. AI-generated captions can mishear words. Alternative text can miss the important part of an image. Translations can lose meaning. A person should review accessibility outputs before relying on them.
Design for people first
AI should not be used as a shortcut for poor design. Clear language, readable pages, keyboard navigation, good contrast, and meaningful structure still matter. AI can help create content, but accessibility should be built into the experience.
Practical scenario: improving a product page
A website owner can ask AI to review a product page for unclear headings, missing image descriptions, and complicated wording. This can reveal accessibility problems that are easy to miss when the creator already knows the page well.
The owner should still test the page with keyboard navigation, screen-reader-friendly structure, and real user needs in mind. AI suggestions are a useful checklist, not a complete accessibility audit.
Best takeaway: AI can make information easier to reach, but accessibility is strongest when human review and inclusive design stay central.
