What it does
Walks you through writing alt text the right way: decide whether the image is decorative (empty alt), informational (describe what matters), or functional (describe the action). Enforces a length budget (~125 characters) and flags common mistakes like "image of…" and redundant captions.
Pair with image dimensions checker, contrast checker, and social media image sizes for a quick accessibility pass.
