Write a voice brief that includes your audience profile, real examples of your own best community posts, the specific words and phrases that define your style, and explicit notes on what you never say — then test the agent’s output against that brief before running it live.
Voice Is Not Something the Agent Figures Out on Its Own
Community tone is not generic. The way a no-nonsense business coach talks to her community of experienced consultants is completely different from the way a warm, supportive wellness educator talks to beginners who are nervous about technology. An agent that is not briefed on the difference will split the difference — producing something blandly professional that fits no one particularly well.
Your voice brief is the single document that prevents this. Think of it as the onboarding packet for a new team member who will be posting in your community every day. The more specific that packet is, the faster they sound like you — and the same is true for your agent.
What a Good Voice Brief Contains
Start with your audience in two or three sentences: who they are, what they are working toward, and the emotional context they are operating in when they open your community. A 52-year-old health coach building her first online program feels different from a 35-year-old marketing consultant scaling his third. That context shapes everything the agent writes.
Next, describe your tone in concrete terms. Not just “warm and supportive” — those are too vague to be actionable. Instead: “I use short sentences. I talk directly to the reader using ‘you.’ I never use corporate jargon. I occasionally use humor but it is dry, not slapstick. I always end posts with a question or an invitation to respond.” Behavioral descriptions produce behavioral outputs.
Then paste in three to five examples of your best community posts — the ones that got the most replies, the ones you felt proudest of, the ones that sounded most like you. Label what makes each one work: “This one worked because it was honest about a struggle I had. This one worked because the question at the end was easy to answer.” Those labels help the agent understand not just the what but the why.
Finally, add an explicit “never say” list. Words or phrases that feel off-brand, too formal, too casual, or simply not yours. This negative space is just as important as the positive examples — it defines the boundaries of your voice clearly.
Testing Before Going Live
Before scheduling automated posts, run the agent manually three times on different prompt types and read the output against your voice brief. If something sounds off, identify the specific element — word choice, sentence structure, tone — and update the brief with a correction and an example of what you would have written instead. Two or three rounds of this calibration produces an agent that consistently sounds like you.
The Simple Rule
Your voice brief is a living document. Update it when you notice something the agent wrote that did not feel right. Over time, the brief becomes a precise map of your community voice — and the agent’s output becomes indistinguishable from your own.
