Banner Forge — brief in, campaign banners out

A banner design studio in the browser. The free lane is a real engine: ten platform formats at exact pixel dimensions, eight art-direction styles as seeded procedural SVG backgrounds, safe zones and adaptive type fitting, a design-rule lint that measures 4.5:1 contrast, the action-verb CTA rule and the 20% ad text ratio, and SVG + exact-dimension PNG export. The AI pass turns a brief into three distinct art directions — palette, copy, style, layout, seeds — rendered by the same engine and checked by the same lint. A derived work of the banner-design skill by @nextlevelbuilder (ckm-3abanner-design, MIT).

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
