The irony of AI content generation is that it's made brand voice more important, not less. When anyone can generate a competent LinkedIn post in 10 seconds, the only differentiator is whether it sounds like your business or like everyone else's. AI writes fluently in any voice. But first you need to define yours.
The brand voice framework
A brand voice document doesn't need to be long. It needs to be specific enough that someone (or something) who's never met you can write in your voice after reading it. Four components:
1. Personality descriptors
Pick three to five adjectives that describe how your brand communicates. Not what you sell. How you talk. Examples: "Warm, direct, expert, occasionally irreverent." Or: "Calm, precise, reassuring, never patronising." These descriptors become the guardrails for every piece of content.
2. Audience definition
Who are you talking to? Not a demographic. A person. "Sarah, 38, runs a physiotherapy clinic in Geelong, has two kids, doesn't have time for marketing but knows she needs to do it." When the AI knows who it's talking to, it adjusts complexity, references, and assumptions.
3. Language rules
The specific dos and don'ts of your language. These matter more than you'd expect:
- Do we use contractions? ("We're" vs "We are")
- Do we use jargon? (Industry insiders vs general public)
- Do we use humour? (And what kind?)
- Do we swear? (Some brands do, effectively)
- Australian English specifically? ("Colour" not "color")
4. Sample content
Three to five examples of your best existing content. The posts that made people comment "that's so you." These samples give AI a concrete reference point, not just abstract rules.
Putting it into practice
Brand and Go's brand profile captures all four components during onboarding. When you generate content. Posts, captions, content plans. The AI references your voice profile before writing a single word. The result sounds like you dictated it, not like a robot guessed.
The test
Read your last 10 social media posts with fresh eyes. Could a stranger tell they were all written by the same business? If not, your voice isn't defined yet. That's not a failure. It's a starting point.
