An agent-native design tool for creative professionals that uses HTML and CSS as its rendering engine
Build a design environment where designers can work through direct visual manipulation while AI agents work directly with the same HTML, CSS, and codebase. The product combines product design, brand design, graphics, image generation, shaders, editable live-site snapshots, and design-to-code workflows so one person can design, iterate, and ship without a traditional designer-to-developer handoff.

From Y Combinator — How To Design In The Agent Era at 01:07
Problem: Traditional design tools use custom rendering engines that are difficult for agents to operate, while separate design and code systems drift out of sync. AI-generated designs also tend to look generic, overuse bold typography and decorative elements, and fail to communicate a distinctive or trustworthy brand.
For: Designers, creative professionals, founders, engineers, salespeople, and agentic software teams that need to create and ship polished product or brand experiences quickly.
