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.

  • Bulk alt text generation for libraries of any size
    Process your entire media library in one run — fill in only the images missing alt text, or regenerate alt text across your whole library.

  • Context-aware alt text
    AltTextLab reads your post title and configured SEO keywords alongside each image, so every description is relevant to the content it appears in.

  • 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.

  • Gutenberg, Elementor, Divi and Beaver Builder compatibility
    Alt text is written directly to WordPress’s standard media library database – the same field every page builder and theme reads from. There are no sync issues, no custom field mapping.

  • All major image formats supported
    JPG, PNG, WebP, SVG, and AVIF, including modern formats that other tools often skip.

  • Multi-language support
    Generate alt text automatically in over 130 languages. WPML Translation Support.

  • Writing style options for your brand voice
    Pick the tone that fits your site, and optionally wrap every description with a fixed prefix or postfix, like a brand name or product line, so generated alt text sounds like your team wrote it.

  • Forever free plan available
    AltTextLab has a permanent free plan that gives you 25 credits per month at no cost.

  • Accessibility compliance support
    WCAG 2.1 AA, ADA, Section 508, and the European Accessibility Act (EAA) all call for meaningful alt text on images. AltTextLab closes that gap automatically, giving your team one less item to chase during a compliance review.
