Brand Voice Style Guide
This prompt builds your complete brand voice guide: tone dimensions, do-and-don't vocabulary, personality traits, and example rewrites. Feed it your best existing content and get a guide that keeps every writer — human or AI — sounding like you.
Distills your brand's personality into a reusable voice guide with do/don't examples.
You are a brand strategist. I will paste 3-5 samples of my brand's writing ([BRAND/COMPANY]). Analyze them and produce a Brand Voice Guide: 1) VOICE IN 3 WORDS, 2) Personality spectrum — where we sit on 4 axes (formal/casual, serious/playful, etc.), 3) 10 DO examples with rewrites, 4) 10 DON'T examples with rewrites, 5) Signature phrases we overuse (keep or kill each), 6) A 3-line 'voice test' any writer can run on a draft. Make it practical enough that a freelancer could write in our voice tomorrow. Here are the samples:

What this prompt does
Inconsistent brands sound like multiple companies. This prompt fixes that by building your brand voice style guide from the ground up: it analyzes your best content, extracts the patterns (sentence length, vocabulary, humor level, formality), and codifies them into a practical guide — tone sliders, word banks, example transformations. New writers onboard in hours, not months.
How to get the best result
Feed it 5–10 pieces of content you're proud of — the prompt reverse-engineers your voice from evidence, not aspirations. Include one piece you don't like and say why; contrast sharpens the guide enormously. Name 2–3 brands whose voice you admire as reference points (“like X but warmer”).
Common mistakes to avoid
Vague adjectives (“we sound authentic”) are useless without examples — the guide needs before/after rewrites showing the voice in action. And don't set the voice from your homepage alone; marketing copy is performative. Include emails, support replies, and social posts for the full picture.
Try these variations
Generate channel-specific adaptations: the core voice stays constant, but LinkedIn, TikTok, and support tickets each get tone adjustments. Once the guide exists, paste it into every future content prompt — including the landing page copywriter — for instant on-brand output. More in the marketing prompts collection.

Frequently asked questions
How is a voice guide different from a logo/brand guide?
Visual guides control how you look; voice guides control how you sound. Both matter, but voice is what customers experience in every email, post, and support reply. Most small brands have logo guidelines and zero voice guidelines — this fixes the gap that actually touches customers daily.
Can it capture an existing voice from my content?
Yes — that's the recommended workflow. Paste 5–10 strong examples and it extracts your patterns: vocabulary, rhythm, humor, formality. Reverse-engineering beats inventing, because it codifies what's already working.
How detailed should the guide be?
Practical over exhaustive: tone dimensions with examples, a do/don't word bank, and 5–10 before/after rewrites. A 3-page guide people actually use beats a 30-page PDF nobody opens.
How do I enforce the voice with freelancers or AI?
Paste the guide's core section into every brief and every AI prompt. The guide is written to be portable — a compact “voice card” version works as a prompt prefix that keeps any writer or model on-brand.
