Key features

One-click alt text generation

Select any image in the Designer and click Generate. AltTextLab reads the image in context and writes an accurate, relevant description applied directly to the image element's alt attribute.

Bulk generation

Run bulk generation to process every image on the current page in one pass. Perfect for image-heavy pages.

SEO keyword integration

Specify target keywords in your AltTextLab settings, and they are woven naturally into every generated description. Useful for Webflow sites where image search and AI visibility matter for SEO.

Customizable writing styles

Choose between descriptive, neutral, minimal, or matter-of-fact tones. Set a preferred style per project, and every generated description follows it.

WCAG 2.1 AA compliant output

Every generated alt text meets screen reader standards, so your Webflow site passes accessibility audits for ADA, EAA, and Section 508 without additional manual editing.
