# Brainy Documentation

> The multi-dimensional AI database with Triple Intelligence — vector search, graph traversal, and metadata filtering in one unified API.

## Quick Start

```typescript
import { Brainy, NounType, VerbType } from '@soulcraft/brainy'

const brain = new Brainy()
await brain.init()

// Add entities — data is embedded for semantic search, metadata is indexed for filtering
const id = await brain.add({
  data: 'Revolutionary AI Breakthrough',
  type: NounType.Document,
  metadata: { category: 'technology', rating: 4.8 }
})

// Search with Triple Intelligence
const results = await brain.find({
  query: 'artificial intelligence',              // Semantic search (on data)
  where: { rating: { greaterThan: 4.0 } },       // Metadata filter
  connected: { from: authorId, depth: 2 }         // Graph traversal
})
```
