Brainy

🧠 Brainy - The Knowledge Operating System

The world's first Knowledge Operating System where every piece of knowledge - files, concepts, entities, ideas - exists as living information that understands itself, evolves over time, and connects to everything related. Built on revolutionary Triple Intelligence™ that unifies vector similarity, graph relationships, and document filtering in one magical API.

Why Brainy Changes Everything: Traditional systems trap knowledge in files or database rows. Brainy liberates it. Your characters exist across stories. Your concepts span projects. Your APIs remember their evolution. Every piece of knowledge - whether it's code, prose, or pure ideas - lives, breathes, and connects in a unified intelligence layer where everything understands its meaning, remembers its history, and relates to everything else.

Framework-first design. Built for modern web development with zero configuration and automatic framework compatibility. O(log n) performance, <10ms search latency, production-ready.

# For Claude Code infinite memory (optional):
brainy conversation setup

💬 Infinite Memory for Claude Code

// One-time setup:
// $ brainy conversation setup

// Claude Code now automatically:
// - Saves every conversation with embeddings
// - Retrieves relevant past context
// - Links code artifacts to conversations
// - Never loses context or momentum

// Use programmatically:
import { Brainy } from '@soulcraft/brainy'

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

// Save conversations
await brain.conversation.saveMessage(
  "How do I implement JWT authentication?",
  "user",
  { conversationId: "conv_123" }
)

// Get relevant context (semantic + temporal + graph)
const context = await brain.conversation.getRelevantContext(
  "JWT token validation",
  { limit: 10, includeArtifacts: true }
)
// Returns: Ranked messages, linked code, similar conversations

🎯 True Zero Configuration

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

// Just this - auto-detects everything!
const brain = new Brainy()
await brain.init()

// Add entities with automatic embedding
const jsId = await brain.add({
    data: "JavaScript is a programming language",
    nounType: NounType.Concept,
    metadata: {
        type: "language",
        year: 1995,
        paradigm: "multi-paradigm"
    }
})

const nodeId = await brain.add({
    data: "Node.js runtime environment",
    nounType: NounType.Concept,
    metadata: {
        type: "runtime",
        year: 2009,
        platform: "server-side"
    }
})

// Create relationships between entities
await brain.relate({
    from: nodeId,
    to: jsId,
    type: "executes",
    metadata: {
        since: 2009,
        performance: "high"
    }
})

// Natural language search with graph relationships
const results = await brain.find({query: "programming languages used by server runtimes"})

// Triple Intelligence: vector + metadata + relationships
const filtered = await brain.find({
    query: "JavaScript",                  // Vector similarity
    where: {type: "language"},           // Metadata filtering
    connected: {from: nodeId, depth: 1}  // Graph relationships
})

🌐 Framework Integration

Brainy is framework-first! Works seamlessly with any modern JavaScript framework:

⚛️ React & Next.js

import { Brainy } from '@soulcraft/brainy'

function SearchComponent() {
  const [brain] = useState(() => new Brainy())

  useEffect(() => {
    brain.init()
  }, [])

  const handleSearch = async (query) => {
    const results = await brain.find(query)
    setResults(results)
  }
}

🟢 Vue.js & Nuxt.js

import { Brainy } from '@soulcraft/brainy'

export default {
  async mounted() {
    this.brain = new Brainy()
    await this.brain.init()
  },
  methods: {
    async search(query) {
      return await this.brain.find(query)
    }
  }
}

🅰️ Angular

import { Injectable } from '@angular/core'
import { Brainy } from '@soulcraft/brainy'

@Injectable({ providedIn: 'root' })
export class BrainyService {
  private brain = new Brainy()

  async init() {
    await this.brain.init()
  }

  async search(query: string) {
    return await this.brain.find(query)
  }
}

🔥 Other Frameworks

Brainy works with any framework that supports ES6 imports: Svelte, Solid.js, Qwik, Fresh, and more!

Framework Compatibility:

• ✅ All modern bundlers (Webpack, Vite, Rollup, Parcel)
• ✅ SSR/SSG (Next.js, Nuxt, SvelteKit, Astro)
• ✅ Edge runtimes (Vercel Edge, Cloudflare Workers)
• ✅ Browser and Node.js environments

📋 System Requirements

Node.js Version: 22 LTS or later (recommended)

• ✅ Node.js 22 LTS - Fully supported and recommended for production
• ✅ Node.js 20 LTS - Compatible (maintenance mode)
• ❌ Node.js 24 - Not supported (known ONNX runtime compatibility issues)

Important: Brainy uses ONNX runtime for AI embeddings. Node.js 24 has known compatibility issues that cause crashes during inference operations. We recommend Node.js 22 LTS for maximum stability.

If using nvm: nvm use (we provide a .nvmrc file)

🚀 Key Features

World's First Triple Intelligence™ Engine

The breakthrough that enables The Knowledge Operating System:

• Vector Search: Semantic similarity with HNSW indexing
• Graph Relationships: Navigate connected knowledge like Neo4j
• Document Filtering: MongoDB-style queries with O(log n) performance
• Unified in ONE API: No separate queries, no complex joins
• First to solve this: Others do vector OR graph OR document—we do ALL

The Knowledge Operating System with Infinite Expressiveness

Enabled by Triple Intelligence, standardized for everyone:

• 31 Noun Types × 40 Verb Types: 1,240 base combinations
• ∞ Expressiveness: Unlimited metadata = model ANY data
• One Language: All tools, augmentations, AI models speak the same types
• Perfect Interoperability: Move data between any Brainy instance
• No Schema Lock-in: Evolve without migrations

Natural Language Understanding

// Ask questions naturally
await brain.find("Show me recent React components with tests")
await brain.find("Popular JavaScript libraries similar to Vue")
await brain.find("Documentation about authentication from last month")

🧠🌐 Virtual Filesystem - Intelligent File Management

Build file explorers, IDEs, and knowledge systems that never crash from infinite recursion.

• Tree-Aware Operations: Safe directory listing prevents recursive loops
• Semantic Search: Find files by content, not just filename
• Production Storage: Filesystem and cloud storage for real applications
• Zero-Config: Works out of the box with intelligent defaults

import { Brainy } from '@soulcraft/brainy'

// ✅ CORRECT: Use persistent storage for file systems
const brain = new Brainy({
  storage: {
    type: 'filesystem',    // Persisted to disk
    path: './brainy-data'  // Your file storage
  }
})
await brain.init()

const vfs = brain.vfs()
await vfs.init()

// ✅ Safe file operations
await vfs.writeFile('/projects/app/index.js', 'console.log("Hello")')
await vfs.mkdir('/docs')
await vfs.writeFile('/docs/README.md', '# My Project')

// ✅ NEVER crashes: Tree-aware directory listing
const children = await vfs.getDirectChildren('/projects')
// Returns only direct children, never the directory itself

// ✅ Build file explorers safely
const tree = await vfs.getTreeStructure('/projects', {
  maxDepth: 3,          // Prevent deep recursion
  sort: 'name'         // Organized results
})

// ✅ Semantic file search
const reactFiles = await vfs.search('React components with hooks')
const docs = await vfs.search('API documentation', {
  path: '/docs'  // Search within specific directory
})

// ✅ Connect related files
await vfs.addRelationship('/src/auth.js', '/tests/auth.test.js', 'tested-by')

// Perfect for: File explorers, IDEs, documentation systems, code analysis

🚨 Prevents Common Mistakes:

• ❌ No infinite recursion in file trees (like brain-cloud team experienced)
• ❌ No data loss from memory storage
• ❌ No performance issues with large directories
• ❌ No need for complex fallback patterns

📖 VFS Quick Start → | 🎯 Common Patterns →

Your knowledge isn't trapped anymore. Characters live beyond stories. APIs exist beyond code files. Concepts connect across domains. This is knowledge that happens to support files, not a filesystem that happens to store knowledge.

🎯 Zero Configuration Philosophy

Brainy automatically configures everything:

import { Brainy } from '@soulcraft/brainy'

// 1. Pure zero-config - detects everything
const brain = new Brainy()

// 2. Custom configuration
const brain = new Brainy({
  storage: { type: 'memory' },
  embeddings: { model: 'all-MiniLM-L6-v2' },
  cache: { enabled: true, maxSize: 1000 }
})

// 3. Production configuration
const customBrain = new Brainy({
    mode: 'production',
    model: 'q8',           // Optimized model (99% accuracy, 75% smaller)
    storage: 'cloud',     // or 'memory', 'disk', 'auto'
    features: ['core', 'search', 'cache']
})

What's Auto-Detected:

• Storage: S3/GCS/R2 → Filesystem → Memory (priority order)
• Models: Always Q8 for optimal balance
• Features: Minimal → Default → Full based on environment
• Memory: Optimal cache sizes and batching
• Performance: Threading, chunking, indexing strategies

Production Performance

• 3ms average search - Lightning fast queries
• 24MB memory footprint - Efficient resource usage
• Worker-based embeddings - Non-blocking operations
• Automatic caching - Intelligent result caching

🎛️ Advanced Configuration (When Needed)

Most users never need this - zero-config handles everything. For advanced use cases:

// Model is always Q8 for optimal performance
const brain = new Brainy()  // Uses Q8 automatically

// Storage control (auto-detected by default)
const memoryBrain = new Brainy({storage: 'memory'})     // RAM only
const diskBrain = new Brainy({storage: 'disk'})         // Local filesystem  
const cloudBrain = new Brainy({storage: 'cloud'})       // S3/GCS/R2

// Legacy full config (still supported)
const legacyBrain = new Brainy({
    storage: {forceMemoryStorage: true}
})

Model Details:

• Q8: 33MB, 99% accuracy, 75% smaller than full precision
• Fast loading and optimal memory usage
• Perfect for all environments

Air-gap deployment:

npm run download-models        # Download Q8 model
npm run download-models:q8     # Download Q8 model

📚 Core API

search() - Vector Similarity

const results = await brain.search("machine learning", {
    limit: 10,                    // Number of results
    metadata: {type: "article"}, // Filter by metadata
    includeContent: true          // Include full content
})

find() - Natural Language Queries

// Simple natural language
const results = await brain.find("recent important documents")

// Structured query with Triple Intelligence
const results = await brain.find({
    like: "JavaScript",           // Vector similarity
    where: {                      // Metadata filters
        year: {greaterThan: 2020},
        important: true
    },
    related: {to: "React"}      // Graph relationships
})

CRUD Operations

// Create entities (nouns)
const id = await brain.add(data, { nounType: nounType, ...metadata })

// Create relationships (verbs)
const verbId = await brain.relate(sourceId, targetId, "relationType", {
    strength: 0.9,
    bidirectional: false
})

// Read
const item = await brain.getNoun(id)
const verb = await brain.getVerb(verbId)

// Update
await brain.updateNoun(id, newData, newMetadata)
await brain.updateVerb(verbId, newMetadata)

// Delete
await brain.deleteNoun(id)
await brain.deleteVerb(verbId)

// Bulk operations
await brain.import(arrayOfData)
const exported = await brain.export({format: 'json'})

🌐 Distributed System (NEW!)

Zero-Config Distributed Setup

// Single node (default)
const brain = new Brainy({
    storage: {type: 's3', options: {bucket: 'my-data'}}
})

// Distributed cluster - just add one flag!
const brain = new Brainy({
    storage: {type: 's3', options: {bucket: 'my-data'}},
    distributed: true  // That's it! Everything else is automatic
})

How It Works

• Storage-Based Discovery: Nodes find each other via S3/GCS (no Consul/etcd!)
• Automatic Sharding: Data distributed by content hash
• Smart Query Planning: Queries routed to optimal shards
• Live Rebalancing: Handles node joins/leaves automatically
• Zero Downtime: Streaming shard migration

Real-World Example: Social Media Firehose

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

// Ingestion nodes (optimized for writes)
const ingestionNode = new Brainy({
    storage: {type: 's3', options: {bucket: 'social-data'}},
    distributed: true,
    writeOnly: true  // Optimized for high-throughput writes
})

// Process Bluesky firehose
blueskyStream.on('post', async (post) => {
    await ingestionNode.add(post, {
        nounType: NounType.Message,
        platform: 'bluesky',
        author: post.author,
        timestamp: post.createdAt
    })
})

// Search nodes (optimized for queries)
const searchNode = new Brainy({
    storage: {type: 's3', options: {bucket: 'social-data'}},
    distributed: true,
    readOnly: true  // Optimized for fast queries
})

// Search across ALL data from ALL nodes
const trending = await searchNode.find('trending AI topics', {
    where: {timestamp: {greaterThan: Date.now() - 3600000}},
    limit: 100
})

Benefits Over Traditional Systems

🎯 Use Cases

Knowledge Management with Relationships

// Store documentation with rich relationships
const apiGuide = await brain.add("REST API Guide", {
    nounType: NounType.Document,
    title: "API Guide",
    category: "documentation",
    version: "2.0"
})

const author = await brain.add("Jane Developer", {
    nounType: NounType.Person,
    role: "tech-lead"
})

const project = await brain.add("E-commerce Platform", {
    nounType: NounType.Project,
    status: "active"
})

// Create knowledge graph
await brain.relate(author, apiGuide, "authored", {
    date: "2024-03-15"
})
await brain.relate(apiGuide, project, "documents", {
    coverage: "complete"
})

// Query the knowledge graph naturally
const docs = await brain.find("documentation authored by tech leads for active projects")

Semantic Search

// Find similar content
const similar = await brain.search(existingContent, {
    limit: 5,
    threshold: 0.8
})

AI Memory Layer with Context

// Store conversation with relationships
const userId = await brain.add("User 123", {
    nounType: NounType.User,
    tier: "premium"
})

const messageId = await brain.add(userMessage, {
    nounType: NounType.Message,
    timestamp: Date.now(),
    session: "abc"
})

const topicId = await brain.add("Product Support", {
    nounType: NounType.Topic,
    category: "support"
})

// Link conversation elements
await brain.relate(userId, messageId, "sent")
await brain.relate(messageId, topicId, "about")

// Retrieve context with relationships
const context = await brain.find({
    where: {type: "message"},
    connected: {from: userId, type: "sent"},
    like: "previous product issues"
})

💾 Storage Options

Brainy supports multiple storage backends:

// Memory (default for testing)
const brain = new Brainy({
    storage: {type: 'memory'}
})

// FileSystem (Node.js)
const brain = new Brainy({
    storage: {
        type: 'filesystem',
        path: './data'
    }
})

// Browser Storage (OPFS) - Works with frameworks
const brain = new Brainy({
    storage: {type: 'opfs'}  // Framework handles browser polyfills
})

// S3 Compatible (Production)
const brain = new Brainy({
    storage: {
        type: 's3',
        bucket: 'my-bucket',
        region: 'us-east-1'
    }
})

🧠 Neural API - Advanced AI Features

Brainy includes a powerful Neural API for advanced semantic analysis:

Clustering & Analysis

// Access via brain.neural
const neural = brain.neural

// Automatic semantic clustering
const clusters = await neural.clusters()
// Returns groups of semantically similar items

// Cluster with options
const clusters = await neural.clusters({
    algorithm: 'kmeans',     // or 'hierarchical', 'sample'
    maxClusters: 5,          // Maximum number of clusters
    threshold: 0.8           // Similarity threshold
})

// Calculate similarity between any items
const similarity = await neural.similar('item1', 'item2')
// Returns 0-1 score

// Find nearest neighbors
const neighbors = await neural.neighbors('item-id', 10)

// Build semantic hierarchy
const hierarchy = await neural.hierarchy('item-id')

// Detect outliers
const outliers = await neural.outliers(0.3)

// Generate visualization data for D3/Cytoscape
const vizData = await neural.visualize({
    maxNodes: 100,
    dimensions: 3,
    algorithm: 'force'
})

Real-World Examples

// Group customer feedback into themes
const feedbackClusters = await neural.clusters()
for (const cluster of feedbackClusters) {
    console.log(`Theme: ${cluster.label}`)
    console.log(`Items: ${cluster.members.length}`)
}

// Find related documents
const docId = await brain.add("Machine learning guide", { nounType: NounType.Document })
const similar = await neural.neighbors(docId, 5)
// Returns 5 most similar documents
