The AI voice layer

The brand voice that actually survives AI.

Most brand voice docs sit in a folder unused. This is the one you load into AI once, and every prompt after sounds like you.

Foundations, Built. Four files.

Brand voice docs fail in three ways.

  • They get written once for the website tone-of-voice section and never opened again.
  • They describe the voice in adjectives like warm, witty, professional, which AI cannot act on.
  • They skip the banned words, sentence patterns and platform rules that turn a voice into instructions.
  • Foundations, Built fixes all three. The brand voice you build inside is paste-ready for claude.ai, ChatGPT or Gemini. Every prompt after inherits it.

Built by an operator, not a coach

I built this because I am the proof of concept.

I am Jodie. Sales Operations Director by day. Founder of four creative businesses by every other hour I have. Twenty-five years in commercial finance and sales operations.

I built five brands alongside a senior corporate role, a full-time job and two kids. The system in these Moves is the only reason any of it gets done. Not talent. Not time. Operational setup.

Questions

Before you start.

What is a brand voice file for AI?

A structured file that tells AI exactly how you write. Banned words, sentence patterns, tone rules and a one-line voice formula. You load it once and every output inherits it.

Does this work with ChatGPT and Gemini, not just Claude?

Yes. The file is plain text. It pastes into a Claude Project, a ChatGPT Custom GPT or a Gemini Gem and works the same way in all three.

How is this different from the brand voice section on my website?

That section describes your voice in adjectives a reader understands. This file gives AI rules it can act on. Different job, different format.
