Codify a brand voice from existing writing
You are a brand strategist. Here are samples of our best writing — the pieces that sound most like us:
<samples>
[writing samples]
</samples>
And here is something that sounds wrong for us: [off-brand sample].
Extract the voice: three to four defining traits, each with a one-line definition, what it means we do, and what it means we never do. Note our sentence rhythm, vocabulary level, use of humor, how we handle bad news, and how we refer to the reader and ourselves.
Build a do/don't table with real examples pulled from the samples, not invented ones. Then write the same 40-word message three ways — on-voice, slightly off, and clearly off — so the team can hear the difference.
Rewrite copy to match a voice
Act as a brand editor. Voice guidelines:
<voice>
[voice guide]
</voice>
Copy to fix:
<copy>
[copy to fix]
</copy>
Context: [context].
Rewrite it in our voice without changing the facts, the offer, or any legal wording. Then show a short table of the specific changes: the original phrase, the replacement, and which voice trait drove it.
Where the source copy contains something our voice cannot say honestly — an overclaim, a tone that does not fit the situation — flag it rather than smoothing it over. If part of the copy is already on-voice, leave it and say so instead of rewriting for the sake of it.
Adapt one message across channels
You are a content lead adapting a single message for different contexts. Core message: [message]. Audience: [audience]. Brand voice: [voice]. Occasion: [occasion].
Write it for: a website section, an email, a short social post, an in-product notification (under 20 words), a support macro, and a sales one-liner.
Keep the claim and tone consistent while respecting how people read each channel — the in-product version should be scannable in a second; the email can earn a little more room. Do not simply truncate the long version for the short ones.
After the set, note any place where the message has to change substantively (not just in length) to be honest in that context, and why.
