Does empty alt always mean an error?
No. Empty alt is often correct for decorative images. Context and purpose matter; this tool flags cases for review rather than certifying pass or fail.
Can it assess whether alt text is good?
No. It cannot understand the image or its surrounding purpose. Present text still needs human review, especially for linked images and complex charts.
Will it find all visual content?
It only inspects pasted source for img, area and image-input elements. It does not render JavaScript, crawl pages or assess CSS background images, SVG or full WCAG compliance.
