Brand Voice Profile Builder

Extract and codify a consistent voice from source material so all content sounds like the same person.

When to Use

• Setting up content strategy for a new channel
• Ensuring consistency across LinkedIn, email, website
• Onboarding a new writer or AI tool to match existing voice
• Refining voice after analyzing what performs best

Process

Step 1: Gather Source Material

Ask the user for 5-10 examples of writing they like (their own or aspirational):

• LinkedIn posts that performed well
• Emails that got replies
• Messages that felt natural
• Writing from others they want to emulate

Step 2: Extract Patterns

Analyze the source material for:

Sentence Structure

• Average sentence length (short/medium/long)
• Rhythm pattern (short-short-long? Varied? Punchy?)
• Paragraph length
• Use of fragments vs complete sentences

Tone Markers

• Formality level (1-5 scale)
• Humor frequency and type
• Directness level
• Emotion display (reserved vs expressive)

Vocabulary

• Words they use often (signature phrases)
• Words they never use (anti-patterns)
• Jargon level (technical vs accessible)
• Filler words to avoid

Structural Habits

• How they open (question? statement? story?)
• How they close (CTA? question? insight?)
• Use of lists, headers, bold
• Capitalization patterns

Step 3: Build Voice Profile

# Voice Profile: [Name/Brand]

- [Pattern to follow — with example]

## Don't
- [Anti-pattern — with example of what to avoid]

## Sentence Rhythm

- [Phrase they use naturally]

## Banned Words
- [Word/phrase to never use]
- [Word/phrase to never use]

## Tone by Channel
| Channel | Formality | Length | Special Notes |
|---------|-----------|--------|---------------|
| LinkedIn | [1-5] | [range] | [notes] |
| Email | [1-5] | [range] | [notes] |
| WhatsApp | [1-5] | [range] | [notes] |

Step 4: Validate

Generate 2-3 sample pieces using the profile. Ask the user: "Does this sound like you?" Adjust based on feedback.

Output

Save the voice profile to docs/voice-profile.md (or user-specified location). This profile is then referenced by content-marketer and sales-automator agents.

Notes

• Voice profiles should be updated quarterly based on what's performing
• Different channels may need slight variations (LinkedIn is more polished than WhatsApp)
• The profile should feel like guidelines, not a straitjacket
