Codex writes and edits real code. Hand it a real design system and it applies your colors, type, and logo across the project instead of default UI.
No signup to preview · Export-ready for Codex
It’s a defaults problem — with no brand system to build against, Codex reaches for the same safe choices every project uses. Give it real tokens and that disappears.
Describe your product and pick a color. Glyph builds a logo, full color system, type pairing, and dark mode in about a minute.
Get a Tailwind config, CSS variables, favicon, and a ready-made Codex build prompt — the exact format Codex understands.
Commit the exported Tailwind config and CSS variables, then instruct Codex to apply the design system across the app. New code inherits the brand from config.
This is an example of what Glyph generates. Your export is filled with your colors, fonts, and logo.
Apply this brand design system across the entire app. Use these exact tokens everywhere — buttons, links, focus rings, headings, backgrounds, borders — and do not fall back to default blue/violet or Inter-for-everything. # Colors (Tailwind + CSS variables) --brand-500: #4F46E5 /* primary */ --brand-600: #4338CA /* primary hover / AA-safe text */ --accent-500: #06B6D4 /* accent */ --ink: #0B0B0F /* text */ --canvas: #FAFAF9 /* background */ Generate the full 50–950 shade ramp for each and wire dark-mode variants. # Typography Heading: "Clash Display", sans-serif Body: "Inter", sans-serif Scale: h1 clamp(2.5rem,5vw,4rem) / h2 2rem / body 1rem / 1.6 line-height. # Logo Use the provided SVG mark in the nav (28px tall) and footer (20px tall); favicon at 32px. # Apply Restyle the landing page and app shell with this system. Keep it clean and premium — real spacing, one accent, consistent radius. No stock gradients, no emoji headers.
Reference the committed token files in your instructions; Codex restyles components to match.
No — generate the system, then let Codex do the code.
