Brand Voice & Style Guide Creator for Content Teams

How to Use the Brand Voice & Style Guide Creator Prompt

What This Prompt Does

This prompt generates a complete, professionally structured Brand Voice and Style Guide for any brand. The guide is built for content teams, freelance writers, agency partners, and AI tools — giving everyone a single, authoritative reference for how the brand writes, what words it uses, and what it never says.

The output is not a mood board or a set of vague directional principles. It is a governance document with executable rules, real examples, and an AI calibration block you can paste directly into any AI writing tool.

What You Need to Provide

You must supply five required inputs before the prompt will generate anything. If any of these are missing, the prompt will return an error message instead of proceeding.

• Brand Name: The name of the brand the guide is being written for. It will appear throughout the entire document.
• Brand Description: Explain what the brand does, who it serves, and what makes it different. The more specific you are, the more precise the voice guide will be.
• Sample Content: Paste in three to five real examples of existing brand writing — website copy, emails, ads, social posts, or internal communications. These are analyzed for linguistic patterns and used to build the Vocabulary System.
• Target Audience: Describe your customers in terms of who they are, what they know, what they care about, and what frustrates them. This shapes tone calibration across every content context.
• Brand Competitors: Name two to four competitor brands. These are used to define what your brand explicitly does not sound like — which is just as important as defining what it does.

Optional Inputs

You can also provide three optional inputs to sharpen the output.

• Content Channels: Specify which platforms the guide will cover. Defaults to website, email, social media, and long-form content.
• Banned Words or Phrases: Include any language your brand has already flagged as off-limits.
• Brand Personality Archetypes: Name up to three personality types to anchor tone decisions. If skipped, they will be inferred from your Brand Description and Sample Content.

What the Output Includes

The guide is structured across eight fully executed sections:

• Brand Voice Snapshot — A three-sentence summary for instant writer calibration.
• Core Personality Traits — Three traits with definitions, in-copy examples, and off-brand contrasts.
• Tone by Context — Calibration across at least four content situations.
• Vocabulary System — 20+ approved phrases, 15+ prohibited terms with replacements, and five structural sentence patterns.
• Messaging Hierarchy — Primary message, proof points, and reasons to believe, written as usable copy.
• Grammar and Mechanics — At least ten specific, actionable rules.
• AI Prompt Calibration Block — A ready-to-paste paragraph for any AI writing tool.
• Quick-Reference Cheat Sheet — Five dos, five don’ts, and three before-and-after rewrite examples.

How to Get the Best Results

• Paste real sample content, not idealized writing. Authentic samples produce accurate vocabulary rules.
• Be specific in your Brand Description — vague inputs produce general rules.
• Name real competitors so contrast framing is meaningful and actionable.
• Include any words your team already avoids in the optional Banned Words field.

Where to Use the Output

• Paste the AI Prompt Calibration Block into any AI writing tool to make it immediately on-brand.
• Share the full guide with new writers during onboarding.
• Give the Quick-Reference Cheat Sheet to freelancers on short-term projects.
• Use the Vocabulary System as a checklist during content review and editing.
