🚀 Quick Start

Installation

npm install brainy

Basic Usage

import { BrainyData } from 'brainy'

// Initialize with zero configuration
const brain = new BrainyData()
await brain.init()

// Add entities (nouns) with automatic embedding generation
await brain.addNoun("The quick brown fox jumps over the lazy dog", {
  category: "animals", 
  mood: "playful",
  timestamp: Date.now()
})

await brain.addNoun("Machine learning transforms how we process information", {
  category: "technology",
  mood: "analytical", 
  timestamp: Date.now()
})

// Triple Intelligence: Vector + Graph + Field in one query
const results = await brain.search("animals running fast", {
  where: {
    category: "animals",
    timestamp: { $gte: Date.now() - 86400000 } // last 24 hours
  },
  limit: 10
})

console.log(results)
// [{ id: "...", content: "The quick brown fox...", score: 0.92, metadata: {...} }]

🤖 Model Loading (AI Embeddings)

Brainy uses AI embedding models to understand and process your data semantically. Zero configuration required - models load automatically.

✅ Zero Configuration (Recommended)

const brain = new BrainyData()
await brain.init() // Models download automatically on first use

What happens automatically:

1. Checks for local models in ./models/
2. Downloads All-MiniLM-L6-v2 (384 dimensions) if needed
3. Uses intelligent cascade: Local → CDN → GitHub → HuggingFace
4. Ready to use immediately

🐳 Production/Docker Setup

# Pre-download models during build (recommended)
RUN npm run download-models

# Optional: Force local-only mode  
ENV BRAINY_ALLOW_REMOTE_MODELS=false

🔒 Offline/Air-Gapped Environments

# On connected machine
npm run download-models

# Copy models to offline machine
cp -r ./models /path/to/offline/project/

# Force local-only mode
export BRAINY_ALLOW_REMOTE_MODELS=false

📋 Environment Variables (Optional)

Variable	Default	Description
BRAINY_ALLOW_REMOTE_MODELS	true	Allow/block model downloads
BRAINY_MODELS_PATH	./models	Custom model storage path

🚨 Troubleshooting

• "Failed to load embedding model" → Run npm run download-models
• Slow model downloads → Pre-download during build/CI
• Container memory issues → Pre-download models, increase memory limit

📊 Triple Intelligence in Action

Vector Similarity

// Semantic search across your data
const results = await brain.search("fast animals")
// Finds: "quick brown fox", "racing horses", "cheetah running"

Graph Relationships

// Find related entities and concepts
const related = await brain.findRelated(entityId, {
  depth: 2,
  relationship: "semantic"
})

Field Filtering

// Precise metadata filtering with O(1) performance
const filtered = await brain.search("technology", {
  where: {
    category: "ai",
    rating: { $gte: 4.5 },
    published: { $between: ["2024-01-01", "2024-12-31"] }
  }
})

Combined Intelligence

// All three intelligence types working together
const results = await brain.search("machine learning concepts", {
  where: {
    category: { $in: ["ai", "technology"] },
    difficulty: { $lte: 5 }
  },
  includeRelated: true,
  depth: 2
})

🗄️ Storage Adapters

Brainy supports multiple storage backends with the same API:

File System (Default)

const brain = new BrainyData({
  storage: { type: 'filesystem', path: './data' }
})

Amazon S3 / Compatible

const brain = new BrainyData({
  storage: {
    type: 's3',
    bucket: 'my-brainy-data',
    region: 'us-east-1'
  }
})

Origin Private File System (Browser)

const brain = new BrainyData({
  storage: { type: 'opfs' }
})

Memory (Development)

const brain = new BrainyData({
  storage: { type: 'memory' }
})

🎯 Advanced Querying with find()

Triple Intelligence find() Method

// Natural language queries with automatic intent recognition
const results = await brain.find("show me recent AI articles with high ratings")
// Automatically converts to: vector similarity + field filtering + date ranges

// MongoDB-style queries with semantic awareness
const results = await brain.find({
  $or: [
    { category: "technology" },
    { $vector: { $similar: "artificial intelligence", threshold: 0.8 } }
  ],
  metadata: {
    published: { $gte: "2024-01-01" },
    rating: { $in: [4, 5] }
  }
})

Natural Language Understanding ✅ Available (Basic)

// The find() method understands natural language queries
const results = await brain.find("technology articles about machine learning")
// Basic pattern matching for common queries

// Temporal queries (basic support)
const recent = await brain.find("recent documents")
// Recognizes common time expressions

// The search() method focuses on semantic similarity
const similar = await brain.search("documents similar to machine learning research")
// Pure vector similarity search
