You get 25 free image descriptions without handing over a credit card. AltTextLab generates alt text using AI trained specifically for accessibility and SEO compliance. It works directly in your browser with any website or CMS you're already using.
Speed matters here. Manual alt text creation takes forever.
AltTextLab's custom vision-language model doesn't just look at your images. It reads embedded text within the visuals. It considers what's written around the image on your page. This context-aware approach means you're not getting generic descriptions that miss the point of why you included that specific image.
AltTextLab supports PNG files. JPG files. WebP, AVIF, and SVG up to 17MB. Won't handle larger files though. You can generate alt text in more than 130 languages and integrate SEO keywords directly into descriptions. Everything meets WCAG 2.1 AA and ADA standards for accessibility compliance.
An e-commerce manager updating hundreds of product images would find this useful. Instead of writing alt text for each item manually, they could process their entire catalog and get descriptions that mention key product features while staying accessible. WordPress and WooCommerce integrations make this scenario smooth.
AltTextLab works through browser extensions — Chrome and Firefox both supported. You can also use it with Webflow and Craft CMS. The model learns from human feedback over time, so descriptions should improve as more people use it.
