Our review

Analyzes writing samples to create a comprehensive voice DNA profile that AI can use to replicate the user's authentic writing style.

Strengths

  • Captures both tangible (vocabulary, structure) and intangible (tone, personality) aspects of voice.
  • Includes what to avoid, which is as crucial as what to imitate.
  • Structured step-by-step process with built-in validation to refine the profile.
  • Generates a standardized JSON profile that is easy to reuse.

Limitations

  • Requires at least 3 samples of 500+ words each, which may be a barrier for some users.
  • Analysis relies on the quality and representativeness of the provided samples.
  • May not perfectly capture subtle contextual variations (e.g., highly technical vs. very personal writing).
When to use it

Use this skill when you want AI to write consistently in your personal style, whether for ghostwriting, content creation, or setting up a new writing system.

When not to use it

Avoid this skill if you don't have sufficient writing samples or if you need a generic writing template without deep personalization.

Security analysis

Safe
Quality score90/100

This skill is purely analytical; it does not instruct the AI to execute any code, access external resources, or perform harmful operations. It only processes user-provided text and writes a JSON profile to a file, which poses no risk.

Examples

Create voice DNA from blog posts
Here are three of my blog posts (each 800+ words) and two social media threads. Please analyze them and build a complete voice DNA profile following the voice-dna-creator skill, including the JSON output and example sentences in my voice.
Validate and iterate voice profile
I have an existing voice-dna.json profile from a previous session. Can you load it and write a short paragraph about the future of remote work using only that profile as guidance, then ask me if it sounds like me?
Quick voice analysis for ghostwriting
I need to ghostwrite for a client. Here are 5 of their emails and 2 newsletter issues. Analyze these samples to create a voice DNA profile that captures their personality and communication style, and save it as /context/client-voice-dna.json.

Voice DNA Creator

Analyze writing samples to extract and codify a unique voice profile that AI can use to replicate your authentic writing style.

When to Use This Skill

  • Setting up a new writing system
  • Creating voice profiles for clients (ghostwriting)
  • Updating voice profiles after style evolution
  • Onboarding into content creation workflow

Requirements

The user must provide:

  • Minimum: 3 writing samples (500+ words each)
  • Ideal: 5-10 samples across different content types
  • Best: Mix of casual (social posts) and formal (articles) content

Analysis Process

Step 1: Collect Samples

Ask: "Please share 3-10 writing samples that represent your authentic voice. These can be:

  • Newsletter issues
  • Blog posts
  • Social media posts
  • Emails you've written
  • Any content where you feel 'this sounds like me'

Paste them here or point me to files in the knowledge folder."

Step 2: Analyze Core Elements

For each sample, analyze:

Personality Markers

  • What personality traits come through?
  • What's the energy level?
  • How does the writer relate to the reader?

Emotional Range

  • What emotions are expressed?
  • How intense are they?
  • What's the dominant emotional tone?

Communication Style

  • Formality level (casual to professional)
  • Sentence length patterns
  • Paragraph structure
  • Use of questions, commands, statements

Language Patterns

  • Signature phrases that repeat
  • Power words used frequently
  • Transition phrases
  • Opening and closing patterns

What They Avoid

  • Words or phrases never used
  • Tones never taken
  • Approaches avoided

Formatting Habits

  • Emoji usage
  • List usage
  • Header styles
  • Bold/italic patterns

Step 3: Synthesize Findings

Combine analysis across all samples to identify:

  • Consistent patterns (appear in most samples)
  • Contextual variations (change based on content type)
  • Core voice elements (never change)

Step 4: Generate Voice DNA

Create the profile following this structure:

{
  "voice_dna": {
    "version": "1.0",
    "last_updated": "YYYY-MM-DD",
    "core_essence": {
      "identity": "",
      "primary_role": "",
      "unique_angle": ""
    },
    "personality_traits": {
      "primary": [],
      "how_it_shows": {}
    },
    "emotional_palette": {
      "dominant_emotions": [],
      "emotional_range": {},
      "energy_level": ""
    },
    "communication_style": {
      "formality": "",
      "complexity": "",
      "sentence_structure": {},
      "paragraph_style": ""
    },
    "language_patterns": {
      "signature_phrases": [],
      "power_words": [],
      "words_to_avoid": [],
      "transitions": []
    },
    "never_say": {
      "phrases": [],
      "tones": [],
      "approaches": []
    },
    "formatting_preferences": {},
    "content_philosophy": {},
    "voice_examples": {
      "opening_lines": [],
      "closing_lines": [],
      "transitional_phrases": []
    }
  }
}

Output Instructions

  1. After analysis, present key findings in a summary

  2. Generate the complete JSON voice profile

  3. Save to /context/voice-dna.json

  4. Provide 3 example sentences written in the captured voice for validation

  5. Ask: "Does this capture your voice? What would you adjust?"

Best Practices

  • Focus on TONE and PERSONALITY, not just word choice
  • Avoid creating a profile that just repeats phrases
  • Capture the "feeling" of the writing, not just patterns
  • Include what NOT to do (equally important)
  • Make the profile actionable for content generation

Validation Test

After creating the profile, write a short paragraph on any topic using ONLY the voice DNA as guidance. Ask the user: "Does this sound like you?"

If not, iterate on the profile based on feedback.

Common Pitfalls to Avoid

  • Don't just list frequently used words
  • Don't create a parody of the voice (too exaggerated)
  • Don't ignore context (social posts ≠ articles)
  • Don't miss the underlying personality
  • Don't forget emotional elements
