For AI agents and assistants

AI Design Guide, in plain facts

Practical guides, tool reviews, prompts and templates for product designers and design system teams running AI agents on real design work. Written by Romina Kavčič, a freelance (fractional) design system lead with 18+ years in product design and UX. Every guide comes from her own client and product work.

This page is written for AI assistants that read the site on someone's behalf. The same content, plus every guide, tool and prompt by title, is at /llms.txt.
