Brand voice is the consistent personality, vocabulary, and style an organization uses across its writing, so readers recognize it regardless of who wrote a given piece.
What brand voice covers
Voice is the constant; tone shifts with context. A company can have one voice that is plain and direct, while its tone is lighter in a launch post and more careful in an incident update.
A usable voice guide includes:
- Three or four traits, each with "this, not that" examples.
- Words you use and words you avoid.
- Rules on emoji, hashtags, exclamation marks, and capitalization.
- Topics you do not comment on.
- Product names and how to write them.
An example
"We use short sentences, name the feature first, never say 'excited to announce', and never use more than one hashtag." Those four lines already change how a draft reads.
Why it matters for AI-drafted posts
A model left alone writes in a generic register. If several agents draft for one account, voice drifts faster. Writing the rules down gives every agent the same reference and gives reviewers something concrete to check against.
SocialHandoff stores this as brand memory: voice rules, products, and banned topics. Agents read it with get_brand_memory and can propose updates with update_brand_memory. You can also rewrite a draft in your voice using your own model key. Banned topics also feed the guardrails. Set it up in brand memory.
