What the AI image describer does
Every image on the web should have alt text — for accessibility, for SEO, and for the moment an image fails to load. Writing it by hand for hundreds of images is tedious, so most teams skip it. The AI image describer reads any image and writes the description for you: concise alt text for screen readers, a longer SEO-friendly description for search engines, and a punchy caption for social. Upload, copy, paste — done.
When to use the image describer
- Generate WCAG-compliant alt text for accessibility audits
- Write SEO image descriptions that help pages rank in image search
- Caption product photos for e-commerce listings at scale
- Draft social media copy from a photo in one click
- Describe images for visually impaired users on your site
