🚀 What Can You Build?

💬 AI Chat Apps - That Actually Remember

// Your users' conversations persist across sessions
const brain = new BrainyData()
await brain.add("User prefers dark mode")
await brain.add("User is learning Spanish")

// Later sessions remember everything
const context = await brain.search("user preferences")
// AI knows: dark mode + Spanish learning preference

🤖 Smart Assistants - With Real Knowledge Graphs

// Build assistants that understand relationships
await brain.add("Sarah manages the design team")
await brain.addVerb("Sarah", "reports_to", "John")
await brain.addVerb("Sarah", "works_on", "Project Apollo")

// Query complex relationships
const team = await brain.getRelated("Project Apollo", {
  verb: "works_on",
  depth: 2
})
// Returns: entire team structure with relationships

📊 RAG Applications - Without the Complexity

// Retrieval-Augmented Generation in 3 lines
await brain.add(companyDocs)  // Add your knowledge base
const relevant = await brain.search(userQuery, 10)  // Find relevant context
const answer = await llm.generate(relevant + userQuery)  // Generate with context

🔍 Semantic Search - That Just Works

// No embeddings API needed - it's built in!
await brain.add("The iPhone 15 Pro has a titanium design")
await brain.add("Samsung Galaxy S24 features AI photography")

const results = await brain.search("premium smartphones with metal build")
// Returns: iPhone (titanium matches "metal build" semantically)

🎯 Recommendation Engines - With Graph Intelligence

// Netflix-style recommendations with relationships
await brain.addVerb("User123", "watched", "Inception")
await brain.addVerb("User123", "liked", "Inception")
await brain.addVerb("Inception", "similar_to", "Interstellar")

const recommendations = await brain.getRelated("User123", {
  verb: ["liked", "watched"],
  depth: 2
})
// Returns: Interstellar and other related content

💫 Why Brainy? The Problem We Solve

❌ The Old Way: Database Frankenstein

Pinecone ($750/mo) + Neo4j ($500/mo) + Elasticsearch ($300/mo) + 
Sync nightmares + 3 different APIs + Vendor lock-in = 😱💸

✅ The Brainy Way: One Brain, All Dimensions

Vector + Graph + Search + AI = Brainy (Free & Open Source) = 🧠✨

Your data gets superpowers. Your wallet stays happy.

⚡ Quick Start (60 Seconds)

Open Source (Local Storage)

npm install @soulcraft/brainy

import { BrainyData } from '@soulcraft/brainy'

// Zero configuration - it just works!
const brain = new BrainyData()
await brain.init()

// Add any data - text, objects, relationships
await brain.add("Elon Musk founded SpaceX in 2002")
await brain.add({ company: "Tesla", ceo: "Elon Musk", founded: 2003 })
await brain.addVerb("Elon Musk", "founded", "Tesla")

// Search naturally
const results = await brain.search("companies founded by Elon")

☁️ Brain Cloud (AI Memory + Agent Coordination)

# Auto-setup with cloud instance provisioning (RECOMMENDED)
brainy cloud setup --email your@email.com

# Sign up at app.soulcraft.com (free trial)
brainy cloud auth  # Auto-configures based on your plan

import { BrainyData, Cortex } from '@soulcraft/brainy'
// After authentication, augmentations auto-load
// No imports needed - they're managed by your account!

const brain = new BrainyData()
const cortex = new Cortex()

// Add premium augmentations (requires Early Access license)
cortex.register(new AIMemory())
cortex.register(new AgentCoordinator())

// Now your AI remembers everything across all sessions!
await brain.add("User prefers TypeScript over JavaScript")
// This memory persists and syncs across all devices
// Returns: SpaceX and Tesla with relevance scores

// Query relationships
const companies = await brain.getRelated("Elon Musk", { verb: "founded" })
// Returns: SpaceX, Tesla

// Filter with metadata
const recent = await brain.search("companies", 10, {
  filter: { founded: { $gte: 2000 } }
})

🎯 Real-World Examples

Customer Support Bot with Memory

// Your bot remembers every interaction
await brain.add({
  customerId: "user_123",
  issue: "Password reset",
  resolved: true,
  date: new Date()
})

// Next interaction knows the history
const history = await brain.search(`customer user_123`, 10)
// Bot says: "I see you had a password issue last week. All working now?"

Knowledge Base that Understands Context

// Add your documentation
await brain.add("To deploy Brainy, run npm install @soulcraft/brainy")
await brain.add("Brainy requires Node.js 24.4.1 or higher")
await brain.add("For production, use Brain Cloud for scaling")

// Natural language queries work
const answer = await brain.search("how do I deploy to production?")
// Returns relevant docs about Brain Cloud and scaling

Multi-Agent AI Systems

// Agents share the same brain
const agentBrain = new BrainyData({ instance: 'shared-brain' })

// Sales Agent adds knowledge
await agentBrain.add("Customer interested in enterprise plan")
