about me
Alexander Kaan (1980)
Amsterdam
My work focuses on UX, UI and generative interfaces — crafting creative tools and user-friendly digital experiences. Lately that means open source User Interface tooling.

Play with your app's design. Right in the browser.
Configure your UI in your browser, or straight from your agent via MCP. Every colour, font, radius and spacing in its CSS becomes a knob, and the real app follows 1:1. Nothing is sent to a server and nothing is stored: close the tab and it is all undone. The code comes out as a patch, design tokens, or a DESIGN.md for your agent.
