**The world's only true Vector + Graph database with built-in AI intelligence**
**Sub-millisecond queries across millions of vectors + billions of relationships**
## The Problem: Three Databases for One Search
**"I need semantic search, relationship traversal, AND metadata filtering - that means 3+ databases"**
❌ **Current Reality**: Pinecone + Neo4j + Elasticsearch + Custom Sync = Slow, expensive, complex
✅ **Brainy Reality**: One blazing-fast database. One API. Everything in sync.
## 🚀 Quick Start: 8 Lines to Production
```bash
npm install @soulcraft/brainy
```
```javascript
import { BrainyData } from '@soulcraft/brainy'
const brainy = new BrainyData() // Auto-detects environment
await brainy.init() // Zero configuration
// Add data with relationships
const openai = await brainy.add("OpenAI", { type: "company", funding: 11000000 })
const gpt4 = await brainy.add("GPT-4", { type: "product", users: 100000000 })
await brainy.relate(openai, gpt4, "develops")
// One query, three search paradigms
const results = await brainy.search("AI language models", 5, {
metadata: { funding: { $gte: 10000000 } }, // MongoDB-style filtering
includeVerbs: true // Graph relationships
}) // Semantic vector search
```
**That's it. You just built a knowledge graph with semantic search in 8 lines.**
## 🎯 Key Features: Why Developers Choose Brainy
### ⚡ Blazing Performance at Scale

## 🔥 The Power of Three-in-One Search
```javascript
// This ONE query does what used to require 3 databases:
const results = await brainy.search("AI startups in healthcare", 10, {
// 🔍 Vector: Semantic similarity
includeVerbs: true,
// 🔗 Graph: Relationship traversal
verbTypes: ["invests_in", "partners_with"],
// 📊 Faceted: MongoDB-style filtering
metadata: {
industry: "healthcare",
funding: { $gte: 1000000 },
stage: { $in: ["Series A", "Series B"] }
}
})
// Returns: Companies similar to your query + their relationships + matching your criteria
```
## 🌍 Works Everywhere - Same Code
**Write once, run anywhere.** Brainy auto-detects your environment:
| Environment | Storage | Optimization |
|-------------|---------|-------------|
| 🌐 Browser | OPFS | Web Workers, Memory Cache |
| 🟢 Node.js | FileSystem / S3 | Worker Threads, Clustering |
| ⚡ Serverless | S3 / Memory | Cold Start Optimization |
| 🔥 Edge | Memory / KV | Minimal Footprint |
🔧 Advanced Configuration Options
```javascript
// High-throughput writer
const writer = new BrainyData({
writeOnly: true,
allowDirectReads: true // For deduplication
})
// Read-only search service
const reader = new BrainyData({
readOnly: true,
frozen: true // No stats updates
})
// Custom storage
const custom = new BrainyData({
storage: {
type: 's3',
s3Storage: { bucketName: 'my-vectors' }
},
hnsw: {
maxConnections: 32 // Higher quality
}
})
```

## ⚙️ Configuration (Optional)
Brainy works with **zero configuration**, but you can customize
## 🆚 Why Not Just Use...?
### vs. Multiple Databases
❌ **Pinecone + Neo4j + Elasticsearch** - 3 databases, sync nightmares, 3x the cost
✅ **Brainy** - One database, always synced, built-in intelligence
### vs. Cloud-Only Vector DBs
❌ **Pinecone/Weaviate/Qdrant** - Vendor lock-in, expensive, cloud-only
✅ **Brainy** - Run anywhere, your data stays yours, cost-effective
### vs. Graph DBs with "Vector Features"
❌ **Neo4j + vector plugin** - Bolt-on solution, not native, limited
✅ **Brainy** - Native vector+graph architecture from the ground up
