Overview

The Image Accessibility Text Generator creates descriptive, contextually appropriate alt text for web images to ensure accessibility compliance and improve user experience for visually impaired visitors. Web teams managing large content libraries struggle to write quality alt text at scale, often leaving images without descriptions or using generic placeholders that fail accessibility standards. This agent analyzes images to generate concise, descriptive alt text that conveys essential visual information, maintains appropriate context for the surrounding content, and adheres to WCAG accessibility guidelines. It accelerates accessibility remediation, ensures compliance, and helps organizations build more inclusive digital experiences.

Example prompt

"I'm uploading 50 product images from our e-commerce website that currently lack alt text. These images show various angles and features of our office furniture products (desks, chairs, storage solutions). Generate appropriate alt text for each image that: describes the product type, key visual features, and relevant details (color, material, style) in 125 characters or less; provides context useful for screen reader users to understand the product; follows WCAG 2.1 Level AA guidelines for alt text; distinguishes between primary product images (which need detailed descriptions) and supplemental detail shots (which may need briefer descriptions); and flags any images that appear to be purely decorative and may not require alt text. Format output as a spreadsheet with columns for image filename, generated alt text, character count, and image type (primary/detail/decorative)."
