AI Accessible Content Generation Guidelines

AI writing tools (ChatGPT, Claude, Gemini, Jasper, Notion AI) can produce content faster than any human writer. Speed does not guarantee accessibility. Without explicit guidance, AI-generated content defaults to patterns that may exclude users with disabilities: complex language, missing structural elements, absent alternative text descriptions, and formatting that breaks assistive technology. These guidelines translate accessibility standards into practical AI prompting and review practices.

Structural Accessibility

Heading Hierarchy

AI-generated content should use proper heading hierarchy (H1 through H6) without skipping levels. Screen readers use headings as navigation landmarks; a page that jumps from H2 to H4 breaks that navigation.

Prompt guidance: “Use a single H1 for the page title, H2 for major sections, and H3 for subsections. Do not skip heading levels.”

Lists and Tables

Use semantic lists (ordered and unordered) rather than formatted paragraphs for sequential or grouped items. Tables should include header rows with proper markup, not visual formatting that looks like a table.

Prompt guidance: “Present comparison data in a properly structured table with a header row. Use bulleted lists for non-sequential items.”

Link Text

Links should be descriptive. “Click here” and “learn more” are meaningless to screen reader users who navigate by link list. Each link should make sense out of context.

Prompt guidance: “Write descriptive link text that communicates the destination. Never use ‘click here’ or ‘read more’ as link text.”

Language Accessibility

Reading Level

Target 8th-grade reading level or below for general audiences. Higher complexity is appropriate for specialized professional content but should be a deliberate choice, not a default.

Prompt guidance: “Write at an 8th-grade reading level. Use short sentences (under 20 words average), common vocabulary, and active voice.”

Plain Language Principles

• Front-load important information
• Use concrete rather than abstract language
• Define technical terms on first use
• Avoid jargon, idioms, and culturally specific references without explanation
• Use consistent terminology (do not alternate between synonyms for the same concept)

Inclusive Language

AI models absorb biases from training data. Generated content may use outdated disability language, gender-biased phrasing, or culturally insensitive terms.

Prompt guidance: “Use person-first or identity-first language as appropriate to the disability community. Avoid terms like ‘wheelchair-bound,’ ‘suffers from,’ or ‘handicapped.’ Do not describe disability as inherently negative.”

Media Accessibility

Alt Text for AI-Generated Images

If using AI to generate images, immediately generate alt text using the same or a companion model. Do not publish AI-generated images without descriptions.

Prompt guidance: “For each image, generate alt text that describes the content and function of the image in one to two sentences.”

Caption and Transcript Generation

AI-generated video and audio content must include captions and transcripts. Use AI captioning tools but review output for accuracy before publishing.

Document Format

Generated documents should be tagged for accessibility: proper heading structure, alt text for images, reading order that matches logical flow, and language declaration.

Review Checklist

After generating content with AI, verify:

• Heading hierarchy is sequential (H1, H2, H3 without skips)
• Link text is descriptive when read out of context
• Reading level meets target (use Flesch-Kincaid or similar metric)
• Images have meaningful alt text
• Tables have header rows
• Lists use proper semantic markup
• Language is inclusive and current
• No jargon used without definition
• Color is not the only means of conveying information
• Content is accurate (AI hallucination check)

Platform-Specific Considerations

CMS Publishing

When publishing AI-generated content through WordPress, Drupal, or other CMS platforms, verify that the CMS preserves semantic structure. Rich text editors sometimes strip heading levels or convert lists to formatted paragraphs.

Social Media

Each platform has different accessibility features. Alt text fields, caption options, and formatting constraints vary. Adapt AI-generated content to each platform’s accessibility capabilities.

Email

HTML email has limited accessibility support. Simplify AI-generated content for email: fewer images, inline styles for contrast, and clear text alternatives for any visual elements.

For the underlying AI content creation tools, see generative AI for accessible, inclusive content. For broader content simplification, read AI content simplification and plain language.

Key Takeaways

• AI-generated content is not accessible by default; accessibility must be explicitly prompted and verified.
• Structural elements (headings, lists, tables, descriptive links) are essential for screen reader navigation and must be part of AI content generation prompts.
• Target 8th-grade reading level for general audiences using short sentences, common vocabulary, and active voice.
• Always generate alt text alongside AI-generated images and review AI captions for accuracy.
• A post-generation review checklist covering structure, language, media, and accuracy catches the most common accessibility failures in AI content.
