What it is

A portable brand brain — written for both humans and machines.

BrandPatrol generates a brand.md from your real digital presence: colors sampled from real pixels, typography read off your site, tone of voice extracted from your actual copy, rules synthesized from how you already show up.

The file has YAML frontmatter for tools and readable markdown for humans and LLMs. Tools that understand Google's open design.md spec (Stitch, Figma plugins) consume it directly. AI assistants treat it as ground truth.

Claude (claude.ai)

Recommended
  1. Create a Project for this brand.
  2. In Project knowledge, upload brand.md and design.md.
  3. Paste this into Project instructions:
Always write copy and design output in the voice of {brandName}, using the guidance in brand.md. Reference the Voice & Tone Do/Don't list before you produce anything. When you generate visual specs, follow design.md exactly — never invent colors or fonts.

Claude Code (CLI)

  1. Drop the bundle into your repo (e.g. ./brand/) and add this to CLAUDE.md:
## Brand
All user-facing copy and visual decisions must follow ./brand/brand.md
and ./brand/design.md. Read those before writing any marketing copy,
UI text, or design specs.

Cursor / Windsurf

  1. Place the files in your project root (or .cursor/rules/ in Cursor). Add a project rule:
When generating UI components or copy, use the design tokens from design.md and the voice/messaging guidance from brand.md. Never use hex codes or font families that aren't defined there.

ChatGPT (Custom GPTs)

  1. Create a custom GPT, paste brand.md into Instructions, and upload design.md + brand-profile.json as Knowledge.
  2. The GPT now writes and ideates as your brand without further prompting.

Figma / Stitch / design.md-aware tools

  1. Pass design.md directly. The frontmatter follows the open spec — tools that understand design.md will materialize tokens as variables, styles, or design components.

Image generators (Midjourney, Flux, Sora, …)

  1. Reference mood.jpg as a style image and pull color cues from design.md. Template:
[scene description], in the visual style of {brandName} — color palette: [hex codes from design.md], mood: [imagery_style + personality], composition: [from visual identity]. Reference: mood.jpg.
Prompt recipes

One-liners that just work

Once brand.md is loaded, these prompts get you most of what you need.

Headline pack

Write 8 headlines for [campaign/page] in our brand voice. Use the Key phrases section as templates and respect Voice & Tone Do/Don't.

Page copy

Draft a [hero / about / pricing] page. Pull positioning from Overview, value propositions from Messaging, and stay inside our voice traits.

UI component

Build a [card / hero / nav] component using design.md tokens only. Follow the visual identity description for spacing and feel.

On-brand check

Review this draft against brand.md. Flag any voice violations (Don't list), token violations (off-palette colors, wrong fonts), or rule breaks.
