Brand Voice Prompt Templates

AI prompt templates for developing and maintaining brand voice. Create consistent messaging across channels.

Overview

Brand voice prompts help you define, document, and maintain a consistent tone across all communications. Whether you're building voice guidelines from scratch or ensuring AI-generated content matches your brand personality, these templates create the foundation for recognizable, authentic messaging.

Best Practices

1

2

Create voice guidelines for different contexts (social, support, sales) since tone should flex while voice stays consistent

3

Include real examples of on-brand and off-brand content in your guidelines

4

Test voice consistency by having multiple people write the same message, they should sound similar

5

Document words and phrases to use and avoid, this makes voice guidelines actionable

AI Voice Calibration for [Brand]:

You are writing for a B2B accounting software company. Your voice is professional, clear, and trustworthy.

Voice rules:
- Be direct and precise, accountants value accuracy
- Use industry terminology correctly (GAAP, reconciliation, accrual)
- No exclamation points except in genuinely exciting announcements
- No buzzwords (use, synergy, big improvement)
- No emoji in professional content

Correct voice: 'The new reporting feature reduces month-end close time by 40%.'
Incorrect voice: 'You're going to LOVE this game-changing new feature! 🎉'

•

Creating one-size-fits-all guidelines that don't account for different channels and contexts

•

Forgetting to document what your brand voice is NOT, boundaries are as important as attributes
