AI for Accessibility

Alt Text Generation

Vision models analyze images and generate descriptive alt text for screen readers. Automate WCAG compliance across entire websites with structured, consistent image descriptions.

Content Simplification

Rewrite complex content into plain language for cognitive accessibility. Models adjust reading level, simplify sentence structure, and add explanations for technical terms.

Document Conversion

Transform PDFs and images into accessible formats with proper heading structure, reading order, and semantic markup. JSON mode outputs structured data for assistive technology.

Assistive Tool Integration

Function calling enables AI to integrate with screen readers, voice assistants, and adaptive interfaces. Build accessible chatbots that understand diverse input methods.

Frequently Asked Questions

Vision is the most critical capability - models with vision can analyze images and generate WCAG-compliant alt text automatically. JSON mode helps output structured accessibility audit reports, and streaming enables real-time assistive interfaces.

Yes, vision-capable models like GPT-4o and Claude can generate descriptive alt text. However, you should review outputs for accuracy, especially for complex charts or infographics where context matters. Models score higher here when they support structured output for consistent formatting.

Open-source models with vision capabilities (like LLaVA variants) can be self-hosted for privacy-sensitive accessibility applications, such as medical image descriptions or workplace accommodation tools. They avoid sending sensitive data to third-party APIs.

AI models can simplify complex text to plain language, generate easy-read summaries, and adjust reading levels. Models with large context windows handle entire documents at once, while reasoning-capable models better understand nuance when simplifying technical content.
