AI accessibility for content, websites and media

AI can help draft alt text, captions, plain-language versions and test ideas, but accessibility remains a design, engineering and human responsibility.

Key takeaways

• AI can assist accessibility work but cannot certify conformance.
• Context determines useful alt text, captions and plain language.
• Test the final experience with real assistive technology and users.

Start with the user and standard

Define the content, interaction and relevant accessibility requirements before asking a tool to assist.

Use AI as a first pass

Generated descriptions, captions and remediation suggestions need context, accuracy and editorial review.

Test the real experience

Use keyboard, screen-reader, zoom, contrast, caption and cognitive checks with representative users where possible.

Protect meaning during transformation

A summary, caption or simplified version must preserve the information and action available in the original. Review names, terminology, timing and meaningful visual context.

Do not remove necessary detail merely to make content shorter or easier for a model to process.

Include accessibility in procurement

Ask providers for current accessibility documentation, keyboard and screen-reader behavior, support processes and known limitations. Validate important tasks rather than relying on a statement alone.

Action checklist

1. Define the accessibility requirement and user task.
2. Use AI only for a bounded first pass.
3. Review meaning, language and visual context.
4. Test keyboard, screen reader, zoom, contrast and media alternatives.
5. Record defects and assign accountable remediation.

A sensible next step

Choose one high-traffic page or video and complete a human-led accessibility review of every AI-assisted element. Continue with the practical AI recipes, compare the reviewed AI tools or use the AI Finder to narrow your next decision.
