AutoRAG - Zero-setup knowledge integration with Cloudflare AI and Vectorize

# AutoRAG - Zero-Setup Knowledge Integration

AutoRAG is a next-generation Retrieval-Augmented Generation system built on Cloudflare's global edge network. It provides **zero-setup knowledge integration** with automatic document processing, semantic search, and enterprise-grade security.

## 🚀 Key Features

### Zero Configuration Required
- **Drop & Go**: Upload PDFs to R2 → Instantly searchable
- **Auto-Detection**: Monitors buckets, webhooks, and APIs automatically  
- **Smart Processing**: Handles PDF, images, audio, video with AI

### Cloudflare Native
- **Workers AI**: 10x cost reduction vs OpenAI embeddings
- **Vectorize**: Global vector storage with <100ms queries
- **Edge Deployment**: 300+ locations worldwide
- **Integrated Stack**: R2, D1, KV, Analytics built-in

### Enterprise Ready
- **Data Sovereignty**: Never leaves your Cloudflare account
- **End-to-End Encryption**: AES-256 at rest, TLS 1.3 in transit
- **Audit Logging**: Complete compliance trail
- **Access Controls**: Fine-grained permissions

### Multi-Format Support
- **Documents**: PDF, DOCX, TXT, Markdown, HTML
- **Data**: JSON, CSV, XML
- **Media**: Images (OCR), Audio (transcription), Video (analysis)
- **Sources**: R2, URLs, GitHub, webhooks, email

## 🎯 Quick Start

### 1. Zero-Setup Deployment

```typescript
import { createAutoRAG } from '@nexus/rag';

// Initialize with zero configuration
const autoRAG = createAutoRAG(env);
const { pipeline, manager } = await autoRAG.setup();

// That's it! Your RAG system is ready
```

### 2. Document Upload

```typescript
// Upload any document - it's automatically processed
const result = await fetch('/api/rag/auto/upload', {
  method: 'POST',
  body: formData // Contains your PDF/DOCX/etc
});

// Document is now searchable globally in <30 seconds
```

### 3. Intelligent Queries

```typescript
// Query with natural language
const response = await fetch('/api/rag/auto/query', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    query: "How do I implement authentication?",
    userId: "user-123"
  })
});

const { answer, sources, performance } = await response.json();
```

## 🏗️ Architecture

```

### How It Works

1. **Automatic Detection**: Monitors R2 buckets, webhooks, and other sources
2. **Smart Processing**: Uses Cloudflare AI to extract text, analyze images, transcribe audio
3. **Intelligent Chunking**: Preserves document structure while optimizing for retrieval  
4. **Vector Generation**: Creates embeddings using BGE models
5. **Global Distribution**: Stores vectors in Vectorize for worldwide <100ms access
6. **Hybrid Retrieval**: Combines vector similarity with keyword matching
7. **Context-Aware Generation**: Uses LLaMA models for accurate, sourced answers

## 💡 Use Cases

### Customer Support
```typescript
// Upload help docs → Instant customer support bot
await pipeline.ingest([{
  source: './help-docs/',
  type: 'file',
  recursive: true
}]);

// Customers get instant, accurate answers
const response = await pipeline.query({
  query: "How do I reset my password?",
  includeSource: true
});
```

### Internal Knowledge Base
```typescript
// Connect company wiki, policies, procedures
await pipeline.ingest([
  { source: 'https://wiki.company.com', type: 'url' },
  { source: 'policies.pdf', type: 'file' },
  { source: 'procedures/', type: 'file', recursive: true }
]);

// Employees find information instantly
```

### Product Documentation
```typescript
// Ingest technical specs, API docs, code repos
await pipeline.ingest([
  { source: 'https://github.com/company/docs', type: 'github' },
  { source: 'api-specs.json', type: 'file' },
  { source: 'technical-guides/', type: 'file' }
]);
```

## 🛡️ Enterprise Security

### Data Sovereignty
```typescript
const securityManager = createEnterpriseSecurityManager(env, 'strict');

// All data stays in YOUR Cloudflare account
// No cross-account access
// Regional data residency options
```

### Access Controls
```typescript
// Fine-grained permissions
await securityManager.grantPermission('user-123', 'documents:read');
await securityManager.grantPermission('admin-456', 'documents:*');

// Automatic query filtering based on permissions
const response = await pipeline.query({
  query: "Show me sensitive documents",
  userId: "user-123" // Only sees what they're allowed to
});
```

### Audit Logging
```typescript
// Every operation is logged
const auditTrail = await securityManager.getAuditTrail(
  'user-123',
  startTime,
  endTime
);

// Compliance reporting built-in
// Immutable audit trail
// Real-time security alerts
```

## 🔄 Continuous Indexing

### Real-Time Updates
```typescript
const indexer = createContinuousIndexer(env, {
  enabled: true,
  sources: ['r2', 'webhook'],
  patterns: ['**/*.{pdf,md,docx}'],
  maxFileSize: 100 * 1024 * 1024
});

await indexer.start();

// New documents are automatically:
// 1. Detected (R2 events, webhooks)
// 2. Processed (extract text, generate embeddings)
// 3. Indexed (stored in Vectorize)
// 4. Ready for search (usually <30 seconds)
```

### Webhook Integration
```typescript
// Connect external systems
app.post('/webhook', async (c) => {
  await indexer.handleWebhookEvent({
    type: 'document_updated',
    payload: await c.req.json(),
    signature: c.req.header('X-Signature')
  });
  
  return c.json({ success: true });
});
```

## ⚡ Performance

```

## 🔧 Advanced Configuration

### Custom Pipeline
```typescript
const advancedConfig = {
  name: 'advanced-rag',
  embedding: {
    model: '@cf/baai/bge-large-en-v1.5',
    provider: 'cloudflare',
    dimensions: 1024,
  },
  chunking: {
    strategy: 'semantic',
    size: 768,
    overlap: 150,
    preserveStructure: true,
  },
  retrieval: {
    topK: 10,
    minSimilarity: 0.8,
    hybridWeight: 0.6,
    useVectorize: true,
  },
  autoIndexing: {
    enabled: true,
    sources: ['r2', 'webhook', 'github'],
    scheduleCron: '0 */6 * * *', // Every 6 hours
    supportedFormats: ['pdf', 'docx', 'md', 'html', 'image', 'audio'],
  },
  security: {
    mode: 'strict',
    encryptionAtRest: true,
    auditLogging: true,
  }
};

const pipeline = await manager.createPipeline(advancedConfig);
```

### Multi-Format Processing
```typescript
// Images → OCR with Cloudflare AI
const imageResult = await processor.processImage(imageBuffer, 'photo.jpg');

// Audio → Transcription with Whisper
const audioResult = await processor.processAudio(audioBuffer, 'meeting.mp3');

// Video → Analysis and transcription  
const videoResult = await processor.processVideo(videoBuffer, 'demo.mp4');

// All formats become searchable text
```

## 📊 Analytics & Monitoring

### Real-Time Analytics
```typescript
// Built-in analytics with Cloudflare Analytics Engine
const stats = await manager.getStats();

console.log({
  totalQueries: stats.totalQueries,
  avgResponseTime: stats.avgResponseTime,
  documentsIndexed: stats.documentsCount,
  topQueries: stats.topQueries
});
```

### Health Monitoring
```typescript
// Comprehensive health checks
const health = await manager.checkHealth();

if (health.status !== 'healthy') {
  console.error('RAG system issues:', health.issues);
  // Automatic alerting and recovery
}
```

## 💰 Pricing Advantages

### Cost Comparison
```
Traditional RAG (OpenAI + Pinecone + AWS):
• Embeddings: $0.10 per 1M tokens
• Vector DB: $70/month per index  
• Compute: $100+/month
• Total: $200+/month for small scale

AutoRAG (Cloudflare):
• Embeddings: $0.001 per 1M tokens (Workers AI)
• Vector DB: $5/month per 1M vectors (Vectorize)  
• Compute: $5/month (Workers)
• Total: $15/month for same scale

= 93% cost reduction
```

### Scaling Economics
