How To Design In The Agent Era

Video summary

Paper pairs HTML/CSS agents with human taste to outdesign AI slop and ship faster

On YC’s Design Review, Paper founder Steven Haney demonstrated an agent-native workflow built on HTML and CSS, letting tools like Conductor, Cursor, and Claude Code generate, edit, and ship designs without a traditional handoff. Paper’s Snapshot turns live websites into editable layers; demos on Legion Health, Scitex, and Maridata showed how reducing bold weights, limiting typography to three sizes, removing decorative cards, purple gradients, pills, icons, and fake metrics can make AI-generated pages more credible. Haney argues agents accelerate translation, resizing, and iteration, but humans still provide taste, context, and organizational decisions. Paper’s 12-person team uses agents heavily for coding and marketing while humans review every line of core product code; brand designer Agu built its interactive Next.js site in about one week. Paper had roughly 25,000 Twitter followers before launching a product and plans components, comments, and organized prototype feedback next.
