Brand Voice

Define how a brand sounds in writing. Document it in a way that anyone (writer, designer, founder, AI assistant) can apply it consistently.

This skill produces a standalone voice document that can either live in the brand style guide or feed into it.

When to use

Defining brand voice for the first time
Auditing existing copy for voice consistency
Training a team, freelancer, or AI assistant on the brand voice
Refining a voice that exists but is inconsistent across applications
Adapting voice when a brand evolves (new audience, new positioning)

When NOT to use

Writing specific copy (use content-and-copy)
Brand visual identity work (use brand-identity)
Documenting a complete brand system (use brand-style-guide, which incorporates voice)
Initial brand exploration (use brand-ideation)

Required inputs

The brand and its positioning
The audience and what they need to hear
5 to 10 examples of existing brand writing (if any)
3 to 5 reference brands whose voice resonates with where this brand should go
Any voice attributes already specified in the brief

The framework: 4 layers

Voice has four layers, stacked. Each layer constrains the one below it.
