Never Re-Explain Your Brand Again: The Brand Voice Brain in 4 Prompts

Why Claude and ChatGPT keep building generic stuff, and the four full copy-paste prompts for Claude Code or Codex that build your brand guide: your look, your voice, your customer, and the CLAUDE.md or AGENTS.md rules that keep it improving every week.

  • Why Claude and ChatGPT go generic: they never got your brand guidelines
  • Prompt 1: Claude Code or Codex pulls your logo, colors, fonts and writing from your website and email into a first brand guide
  • Prompt 2: your AI turns your writing into voice rules and a never-say list
  • Prompt 3: your AI interviews you to build a customer voice guide
  • Prompt 4: wire it into CLAUDE.md or AGENTS.md and set a weekly review that drafts fixes you approve into the guide

A look inside

What's inside

01

Why your AI keeps going off-brand

Most people re-type their brand every time they open a new chat: the colors, the tone, who they sell to.

02

Prompt 1. Your look

What it does: creates a brand folder, asks for your website and email access, then pulls in your logo files, your colors as hex codes, your fonts, your imagery style and everything you've written.

03

Prompt 2. Your voice

What it does: turns your own writing into voice rules: how you sound, the words you always use, the words you'd never say, and three before-and-after rewrites.
