OpenAI
A radically minimal, near-monochrome interface built on pure white canvas with pure-black ink and the custom OpenAI Sans typeface. The landing surface centers a ChatGPT-style prompt box as the hero ("What can I help with?"), surrounded by generous whitespace, soft pill-shaped controls, and a quiet editorial grid of content cards below. Brand voltage is reserved almost entirely for the colorful gradient artwork inside cards — the chrome itself stays black-on-white, functional, and restrained.
