A voice guide writers will actually use
A brand voice guide only works if it is concrete. This builder turns a few personality traits into a usable guide: each trait framed as a clear we-are-but-not boundary, tone notes for different contexts, and before-and-after examples that show the rules applied to real copy rather than described in the abstract.
How it works
You start by choosing three to five personality adjectives — the consistent core of the voice. For each, you write a we-are-but-not line, such as “we are confident, but not arrogant,” which gives writers both the target and the failure mode and stops a trait from drifting off-brand. Tone variations capture how that single voice flexes by context: warmer in onboarding, plainer in error messages, more urgent in a sale. Finally, before-and-after pairs show an off-brand line beside its on-brand rewrite, which is the part writers reach for most. The assembled guide renders for copy into your brand book.
How it works in practice
- Pick traits that are a little distinctive; if every competitor could claim them, they say nothing.
- Always fill in the “but not” half — that boundary is where the guidance actually lives.
- Write tone notes for the moments that matter most: onboarding, errors, and bad news.
- Add at least three before-and-after examples; they teach faster than any rule.
