What is AltTextLab?
AltTextLab is a specialized AI tool for generating accurate, descriptive alt text for images at scale, addressing the dual challenge of web accessibility compliance and SEO image optimization.
It analyzes image content and generates alt text descriptions that convey the essential information in the image to visually impaired users while also incorporating natural language terms that improve image search indexing.
The platform handles the nuance that good alt text requires context a product photo on an e-commerce page needs different alt text than the same product photo in a magazine article. AltTextLab allows teams to configure the context and purpose of images so generated descriptions are appropriate for how the image is being used rather than just what is in it.
AltTextLab serves web development teams, content management platforms, and accessibility compliance programs. For organizations with existing image libraries that lack alt text, the platform provides bulk processing that makes retroactive compliance practical.
For ongoing publishing workflows, the API integration allows alt text generation to happen automatically as new images are uploaded, eliminating the skip behavior that makes accessibility an afterthought in most content workflows.
