AltTextLab – AI Alt Text Generator for WordPress AltTextLab automatically writes accurate, SEO-optimized and accessible alt text for every image in your WordPress media library – the moment you upload, or across your entire existing library in one bulk run. Features Automatic alt text on every upload Every new upload gets alt text generated immediately, no manual trigger needed.

WooCommerce product data built into every alt text AltTextLab reads your product name, brand, color, and material alongside each image to write descriptive alt text that serves both screen reader users, search engines, and LLMs. SEO keywords for better search rankings Specify your own target keywords, or let AltTextLab automatically pull your focus keyphrase from Yoast SEO, Rank Math, SEOPress, All in One SEO, The SEO Framework, SmartCrawl, or Squirrly SEO — either way, it’s woven naturally into every generated alt text. You can also exclude terms you don’t want used.
