# Brand Voice Extractor

Analyze a company's published content to extract their brand voice and writing style. Reads their top content pieces and produces actionable guidelines for matching their voice in future content, outreach, or campaigns.

## Quick Start

```
Extract brand voice for [company]. Use their blog at [url].
```

Or with content already cataloged:
```
Extract brand voice for [client]. Use the content inventory at clients/[client]/research/content-inventory.json.
```

## Inputs

| Input | Required | Source |
|-------|----------|--------|
| **Content URLs** | Yes | User provides, or pulled from site-content-catalog output |
| **Company name** | Yes | For context in the analysis |
| **Number of pages** | No | Default: 15. How many pages to analyze. |

## Process

### Phase 1: Select Content to Analyze

If content URLs are provided directly, use those. Otherwise:

1. Read the content inventory from `site-content-catalog` output
2. Select a diverse sample of 10-20 pages, prioritizing:
   - **Blog posts** (primary voice indicator)
   - **Landing pages** (marketing voice)
   - **Case studies** (storytelling voice)
   - Mix of recent and older content (to detect voice evolution)
   - Mix of topics (to see consistency across subjects)

**Selection heuristic:**
- 8-10 blog posts (mix of how-to, opinion, product updates)
- 2-3 landing pages (homepage, product page, solutions page)
- 2-3 case studies or customer stories (if available)
- 1-2 comparison/vs pages (if available)

### Phase 2: Fetch and Extract Text

For each selected URL:
1. WebFetch the page
2. Extract the main content body (strip nav, footer, sidebar)

- **Use of fragments:** Do they use incomplete sentences for emphasis?

#### D) Formatting Patterns
- **Headers:** Frequency, style (question-based, how-to, numbered)

- **Bold/italic:** How they use emphasis
- **Images/media:** Frequency, types (screenshots, illustrations, photos)
- **CTAs:** Placement, style, frequency, language used
- **Pull quotes/callouts:** Do they use them?

#### E) Content Structure
- **Typical article length:** Short (<800), Medium (800-1500), Long (1500+)
- **Introduction style:** Hook type, length
- **Conclusion style:** Summary, CTA, open question

#### F) Persona & Audience
