Design systems for the AI era

Your design system,
but for AI

LLMs generate content for your brand every day. Most of it looks wrong. BrandAPI gives any AI model your exact colors, typography, and voice via a single API call.

The problem

AI ignores your
brand guidelines

Your team uses AI to write copy, generate code, and design components. The output is fast — and consistently off-brand. Wrong fonts, wrong colors, wrong tone. Because the AI doesn't know your brand exists.

Step 1

Define brand tokens

Colors, typography, spacing, voice guidelines

Old way

Static doc or PDF

LLMs can't read it. AI generates whatever it wants.

Result

Off-brand output

Wrong colors, wrong tone, manual corrections every time

GET /v1/brand/context
// Add this to any LLM prompt — brand context in one call
{
  "brand": "Acme Corp",
  "tokens": {
    "colors": {
      "primary": { "value": "#7c3aed", "usage": "CTAs, links, active states" },
      "background": { "value": "#0a0a0c", "usage": "Primary surface" }
    },
    "typography": {
      "heading": { "family": "Space Grotesk", "weight": "700" },
      "body": { "family": "Inter", "size": "1rem" }
    },
    "voice": {
      "tone": "Direct, confident, no buzzwords",
      "avoid": ["passive voice", "exclamation marks", "marketing fluff"]
    }
  },
  "instructions": "Use these tokens to ensure brand consistency..."
}
How it works

Three steps to machine-readable brand

1

Define your brand tokens

Build your design system in the dashboard — colors, typography scales, spacing, and voice guidelines. Import from existing systems or start fresh with the brand wizard.

2

Get an API endpoint

BrandAPI structures everything into a clean JSON schema optimized for LLM context windows. Generate an API key and your brand is accessible anywhere.

3

LLMs generate on-brand content

Add one API call at the start of any AI workflow — Claude, GPT, Cursor, Copilot. Every generated asset stays on-brand automatically, no manual enforcement needed.

Every AI-generated asset should look like your brand made it
