Give your coding agent real design judgment
A structured skill set that agents load to make typographic, layout, spacing, and color decisions with design intent rather than defaults.
Identifies recurring AI-generated UI clichés such as chip overload, card-in-card nesting, weak hierarchy, and vague calls to action.
Helps the agent stay consistent with the tokens, components, and conventions of your existing design system.
Bakes in contrast, focus, semantic structure, and responsive behavior so built interfaces hold up across devices and audiences.
A free archive of how every AI model answered the same 100 questions
One hundred identical questions covering drawings, websites, writing, images, code and audio, each answered by every model and kept as given.
121 of the 385 models are no longer served on OpenRouter, yet their answers remain viewable, preserving outputs that would otherwise be lost.
Add two to four models with a single click and view their answers to the same questions next to each other.
Explore a magnifiable globe of answers, an index sortable by release date, lab or question, a monthly timeline, and a fast command-K search.
