What is Alt Text Generator AI?

Alt Text Generator is a WordPress plugin that uses computer vision AI to automatically generate alt text descriptions for images on your website. Instead of manually writing alt text for every image, the tool scans your site, identifies images missing descriptions, and creates SEO-friendly alternatives. This serves two purposes: it improves your website's search engine optimisation by adding relevant keywords to image descriptions, and it enhances accessibility for visitors using screen readers. The plugin works directly within WordPress and requires no coding knowledge to set up.
