AltTextLab generates alt text for images using AI. Give it an image, get back a ready-to-use description. Connect it to your CMS, call it from your API, or use the browser extension — it fits into how you already work.

​
Why AltTextLab

  • Accurate descriptions — the AI understands image context, not just what’s visible but what’s relevant. No generic or repetitive output.
  • Any scale — works for a single image or an entire media library of millions. The same engine handles both.
  • Fits your workflow — connects to WordPress, Shopify, Webflow, and more. Or use the web snippet on any site without a plugin.
  • 130+ languages — generate alt text in the language your audience reads.
  • E-commerce mode — uses product name, brand, color, and material to generate descriptions that help shoppers and search engines.
  • Writing style control — choose the tone and level of detail that fits your content, from concise captions to detailed descriptions.
