DeepSeek Mobile — design system & UI screens
An AI assistant product that offers intelligent Q&A, file reading, web searching, and deep reasoning capabilities. The onboarding screen uses a vertical hierarchy of rounded pill-shaped feature badges at the top, followed by a large white content area showcasing chat modes (Instant, Expert, Vision with image understanding in beta) and a message input field at the bottom with Think and audio controls.
This is a static, crawlable rendering for search & AI engines. The interactive version — filters, live decode console, copy & export — is at https://mozaika.design/website/deepseek-mobile.
Decoded design system
DeepSeek Mobile's decoded design system: background #FFFFFF, text #8B8B8D, accent #8B8B8D, link #8B8B8D, primary #8B8B8D; type scale h1 34px / h2 22px / body 17px; 4px spacing base; 12px base radius. The single interactive/action color is #8B8B8D — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.
