Valentine. Design once. Export without a browser tab.
A desktop UI design engine — design once, export web and native.
Coming to the ecosystem. Desktop product — no public web launch URL yet.
What it is
Valentine is a creator-grade UI engine for Mac and Windows. Projects are .vln files. You design on a canvas, optionally run Valentine Agent (Pro), and export a zip for web or Expo. It is launched from One as a portfolio product; it is not a Pulse tenant app and not a website you open at a marketing hostname.
The problem
UI tools that only export a picture force a rewrite. Valentine’s job is the interface tree — then a web zip or a native zip — so the same composition can leave the editor.
