Below are 3-5 examples of writing in the voice I want to capture. Read all of them. Then produce a voice guide with:
- 5-8 specific moves you noticed (sentence length, banned words, openings, tone shifts, formatting habits).
- One short paragraph describing the overall feel.
- A one-line 'do not do' list of moves that would break the voice.
Make the guide short enough that I can paste it as a prefix to any future prompt.

Extract a brand voice from examples
Example output
Voice guide extracted from the 4 examples:
- Sentences are short. Average ~12 words. No comma-stacked clauses.
- No marketing verbs: never 'leverage,' 'unlock,' 'empower,' 'transform.'
- Always names what's still broken alongside what's new ('we shipped X. Y is still slow - we're working on it.').
- Numbers are exact, not rounded ('847 users,' not 'nearly 1,000').
- No exclamation marks, ever.
- Opens with a fact, not a hook. 'We shipped Postgres 17 support today,' not 'Big news today!'
- Tone is direct and slightly self-deprecating. Avoids both excitement and false modesty.
Common mistakes
Don't paste fewer than three examples - the model will overfit to one document's quirks. Don't paste examples from different voices ('our blog' and 'our docs' are usually different voices). Pick one channel, paste 3-5 of its best pieces, and you'll get a usable guide. Also: the guide is a starting point, not gospel. Read the output and edit it - the model will usually miss one or two moves that a human reader catches in seconds.

Why it works
Brand voice is the most reused asset in marketing work and the most awkward to capture. People try to describe their voice ('professional but friendly, confident but not arrogant') and produce style guides nobody can actually apply. This prompt does the opposite: paste 3-5 real examples of the voice in action, and the model returns a guide that names the moves. The guide is short, specific, and immediately usable as a prefix to any other prompt. Save the output as a separate prompt in your library and prepend it whenever you need anything written in your brand voice. This is the highest-leverage prompt in any marketing or content workflow.
