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

How it works

Three steps. Done in 2 minutes.

Register your brand tokens

Add your colors, fonts, logos, and voice guidelines in the dashboard. Import from your existing style guide or build fresh with the brand wizard. Takes about 2 minutes.

Get your API endpoint

BrandAPI generates a structured JSON endpoint optimized for LLM context windows. One API key, one URL — your entire brand system, machine-readable.

Any tool fetches your brand context via API

Cursor, Claude, GPT, custom agents — anything that calls an API gets your exact brand guidelines. No manual copy-paste, no off-brand output, ever again.

AI Integration

How AI agents use BrandAPI

One fetch call puts your entire brand context into any AI prompt. Here's what that looks like in practice.

                            
                            
                            
                        

                        GET /v1/brand/context
                    

{
  "brand": {
    "name": "Acme Corp",
    "colors": {
      "primary": "#6d28d9",
      "background": "#fafafa",
      "text": "#111827"
    },
    "typography": {
      "heading": "Inter 700",
      "body": "Inter 400"
    },
    "voice": {
      "tone": "Direct, confident",
      "avoid": "Jargon, passive voice"
    }
  }
}
