What You Need and Quick Setup Process

What You Need

Claude account (Claude 3.5 Sonnet or Claude 3 Opus recommended)

3-5 samples of your best writing (at least 1,500 words total)

15 minutes of focused time

Quick Setup Process

Step 1: Gather Writing Samples (3 minutes)

Select 3-5 pieces that best showcase your writing style

Include different content types if possible (posts, articles, emails)

Compile them in a single document

Export as PDF

Step 2: Upload to Claude (1 minute)

Start a new Claude conversation

Click "Add content" and upload your PDF

Confirm successful upload

Step 3: Request Style Analysis (1 minute)

Copy and paste this prompt:

Analyze this writing style in detail. Focus on sentence structure, vocabulary, tone, pacing, and unique elements. Be thorough as you'll need to replicate this style later.

Step 4: Generate Style Prompt (2 minutes)

When Claude finishes the analysis, respond with:

Transform this analysis into a comprehensive style guide prompt (800-1200 words) that will enable you to write exactly like me. Include specific instructions about vocabulary, sentence structure, transitions, paragraph length, and any unique quirks.

Step 5: Test the Style (3 minutes)

When you receive the style guide, respond with:

Using this style guide, write a [social post/email/article intro] about [topic relevant to your field]. Keep it under 200 words.

Step 6: Quick Refinement (3 minutes)

Rate the sample (1-10) and provide specific feedback:

That's a [X/10]. You captured my [what worked well] but missed my [what needs improvement]. Please revise the style guide to better reflect these elements.

Step 7: Save Your Ghostwriter (2 minutes)

After Claude provides the updated style guide:

Save the prompt somewhere secure (password manager, note app)

Ask Claude to create a 100-word "refresh" version for quick reference
