Document how your brand sounds before more people start writing for it

This guide helps marketing teams turn a vague sense of voice into practical writing rules. Use it to define personality traits, tone by situation, language to use or avoid, examples by channel, and review rules for keeping copy consistent as the team grows.

Voice principles

Define the stable personality traits that should show up in every piece of brand communication.

Tone by context

Explain how the brand should flex across sales pages, product updates, social posts, support messages, and executive content.

Language rules

Create practical guidance for words to use, words to avoid, claims to substantiate, and phrases that sound off-brand.

Before-and-after examples

Show writers what good looks like with sample rewrites across common marketing and customer touchpoints.

Template sections
