Why "Write in My Voice" Does Not Work
When you tell Claude to "write in my voice" without giving it examples or rules, it produces the average of all content in your general category. That average is generic. Telling Claude to write "warmly and conversationally" produces the average of all warm, conversational content. Showing Claude three pieces of your best content and listing the specific words you never use produces output that sounds like yours.
The principle: adjectives describe voice. Examples and rules teach voice. Claude learns from examples and rules, not from adjective descriptions.
The Voice Document Structure
Your voice in one sentence: Not an adjective list. A real sentence describing how you write and why. "My voice is direct and warm with a contrarian edge -- I challenge what the industry assumes and then show a different way from lived experience."
Words you always use: Your specific vocabulary. The phrases your audience recognizes as coming from you. What you say instead of generic alternatives.
Words you never use: Just as important. List the specific words and phrases that feel wrong -- too corporate, too fluffy, too associated with people you do not want to sound like.
Tone by format: Your voice in a blog post is not identical to your voice in a caption or an email. Name the differences for each format you produce in.
Three real examples: Paste in three pieces of content that sound exactly right. Add one that missed with a note about what was off. Real examples teach more than any description.
