## 🎯 Top 5 Use Cases

These are the most powerful ways to use Open Navigator:

### 📊 1. Hold Governments Accountable

**The Problem:** Cities and school boards claim priorities in meetings but don't fund them.

**The Solution:** Compare meeting transcripts with budget line items to expose gaps between rhetoric and reality.

<div style={{background: '#fff', padding: '20px', borderRadius: '8px', border: '2px solid #4CAF50', margin: '20px 0'}}>
  <div style={{fontFamily: 'monospace', fontSize: '0.95em'}}>
    <div><strong>Meeting:</strong> "Mental health is our top priority" (mentioned 47 times)</div>
    <div><strong>Budget:</strong> Mental health funding: +2% (below inflation)</div>
    <div style={{color: '#F44336', fontWeight: 'bold', marginTop: '15px'}}>⚠️ Gap Detected: Performative Talk</div>
  </div>
  <p style={{marginTop: '20px', fontSize: '0.9em', color: '#666'}}><strong>Data Used:</strong> <code>MEETING</code>, <code>BUDGET</code>, <code>JURISDICTION</code>, <code>TOPIC</code></p>
</div>

### 🗺️ 2. Find Policy Windows for Advocacy

**The Problem:** Advocates miss critical moments when governments are receptive to change.

**The Solution:** Track meeting sentiment, budget cycles, and legislation timing to identify when to act.

<div style={{background: '#fff', padding: '20px', borderRadius: '8px', border: '2px solid #2196F3', margin: '20px 0'}}>
  <div>🟢 <strong>Urgent Opportunity:</strong> Tuscaloosa City Council</div>
  <ul style={{marginTop: '10px', lineHeight: '1.8'}}>
    <li>Budget discussion: April 15 (2 weeks away)</li>
    <li>Sentiment: +0.65 (favorable toward policy)</li>
    <li>Similar cities: 3 passed related ordinances</li>
  </ul>
  <div style={{color: '#4CAF50', fontWeight: 'bold', marginTop: '15px'}}>✅ Action: Submit testimony by April 10</div>
  <p style={{marginTop: '20px', fontSize: '0.9em', color: '#666'}}><strong>Data Used:</strong> <code>OPPORTUNITY</code>, <code>SENTIMENT</code>, <code>DATE_DIMENSION</code>, <code>METRIC_VIEW</code></p>
</div>

### 🏛️ 3. Track Nonprofit Effectiveness

**The Problem:** Donors can't verify if nonprofits deliver on their mission.

**The Solution:** Combine Form 990 financial data with service delivery data and meeting citations.

<div style={{background: '#fff', padding: '20px', borderRadius: '8px', border: '2px solid #FF9800', margin: '20px 0'}}>
  <div><strong>Health Nonprofit A:</strong></div>
  <ul style={{marginTop: '10px', lineHeight: '1.8'}}>
    <li>Revenue: $2.5M (Form 990)</li>
    <li>CEO Salary: $450K (18% of revenue)</li>
    <li>Program spending: 42% (below 65% standard)</li>
    <li>Meeting citations: 0 (not mentioned in city meetings)</li>
  </ul>
  <div style={{color: '#F44336', fontWeight: 'bold', marginTop: '15px'}}>⚠️ Red Flag: High overhead, low community presence</div>
  <p style={{marginTop: '20px', fontSize: '0.9em', color: '#666'}}><strong>Data Used:</strong> <code>NONPROFIT</code>, <code>DONATION</code>, <code>CONSTITUENT</code>, <code>PROGRAM_DELIVERY</code></p>
</div>

### 🗣️ 4. Analyze Public Sentiment & Debate

**The Problem:** It's hard to know how communities really feel about policies.

**The Solution:** Extract sentiment from meeting transcripts, public comments, and video debates.

<div style={{background: '#fff', padding: '20px', borderRadius: '8px', border: '2px solid #9C27B0', margin: '20px 0'}}>
  <div><strong>Topic:</strong> School mask policy</div>
  <ul style={{marginTop: '10px', lineHeight: '1.8'}}>
    <li>Public comments: 127 speakers</li>
    <li>Sentiment breakdown: 58% against, 35% for, 7% neutral</li>
    <li>Board vote: 6-1 to require masks</li>
  </ul>
  <div style={{color: '#FF9800', fontWeight: 'bold', marginTop: '15px'}}>📈 Insight: Board voted against majority sentiment</div>
  <p style={{marginTop: '20px', fontSize: '0.9em', color: '#666'}}><strong>Data Used:</strong> <code>MEETING</code>, <code>VIDEO</code>, <code>OFFICIAL</code>, <code>SENTIMENT</code>, <code>VOTE_EVENT</code></p>
</div>

### 🎓 5. Compare Education Spending Across Districts

**The Problem:** Parents don't know if their school district spends money efficiently.

**The Solution:** Benchmark per-pupil spending, administrative costs, and outcomes across similar districts.

<div style={{background: '#fff', padding: '20px', borderRadius: '8px', border: '2px solid #00BCD4', margin: '20px 0'}}>
  <table style={{width: '100%', fontSize: '0.9em', borderCollapse: 'collapse'}}>
    <thead>
      <tr style={{borderBottom: '2px solid #ddd'}}>
        <th style={{textAlign: 'left', padding: '10px'}}>District</th>
        <th style={{textAlign: 'right', padding: '10px'}}>Per-Pupil</th>
        <th style={{textAlign: 'right', padding: '10px'}}>Admin %</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td style={{padding: '10px'}}>Your District</td>
        <td style={{textAlign: 'right', padding: '10px', fontWeight: 'bold', color: '#F44336'}}>$18,500</td>
        <td style={{textAlign: 'right', padding: '10px', fontWeight: 'bold', color: '#F44336'}}>24%</td>
      </tr>
      <tr style={{background: '#f5f5f5'}}>
        <td style={{padding: '10px'}}>Similar District A</td>
        <td style={{textAlign: 'right', padding: '10px'}}>$14,200</td>
        <td style={{textAlign: 'right', padding: '10px'}}>12%</td>
      </tr>
      <tr>
        <td style={{padding: '10px'}}>Similar District B</td>
        <td style={{textAlign: 'right', padding: '10px'}}>$13,800</td>
        <td style={{textAlign: 'right', padding: '10px'}}>11%</td>
      </tr>
    </tbody>
  </table>
  <div style={{color: '#00BCD4', fontWeight: 'bold', marginTop: '15px'}}>📊 Question: Why are admin costs double the average?</div>
  <p style={{marginTop: '20px', fontSize: '0.9em', color: '#666'}}><strong>Data Used:</strong> <code>JURISDICTION</code>, <code>BUDGET</code>, <code>DEMOGRAPHICS</code>, <code>METRIC_VIEW</code></p>
</div>
