Brainy

The Knowledge Operating System

Every piece of knowledge in your application — living, connected, and intelligent.

Stop fighting with vector databases, graph databases, and document stores. Stop stitching together Pinecone + Neo4j + MongoDB. Brainy does all three, in one elegant API, from prototype to planet-scale.

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

// That's it. You now have semantic search, graph relationships,
// and document filtering. Zero configuration. Just works.

Built by developers who were tired of:

• Spending weeks configuring embeddings, indexes, and schemas
• Choosing between vector similarity OR graph relationships OR metadata filtering
• Rewriting everything when you need to scale from 1,000 to 1,000,000,000 entities

Brainy makes the impossible simple: All three paradigms. One API. Any scale.

See It In Action

30 seconds to understand why Brainy is different:

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

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

// Add knowledge with context
const reactId = await brain.add({
    data: "React is a JavaScript library for building user interfaces",
    type: NounType.Concept,
    metadata: { category: "frontend", year: 2013 }
})

const nextId = await brain.add({
    data: "Next.js framework for React with server-side rendering",
    type: NounType.Concept,
    metadata: { category: "framework", year: 2016 }
})

// Create relationships
await brain.relate({ from: nextId, to: reactId, type: VerbType.BuiltOn })

// NOW THE MAGIC: Query with natural language
const results = await brain.find({
    query: "modern frontend frameworks", // 🔍 Vector similarity
    where: { year: { greaterThan: 2015 } },  // 📊 Document filtering
    connected: { to: reactId, depth: 2 }  // 🕸️ Graph traversal
})

// ALL THREE PARADIGMS. ONE QUERY. 10ms response time.

This is impossible with traditional databases. Brainy makes it trivial.

From Prototype to Planet Scale

The same API. Zero rewrites. Any scale.

👤 Individual Developer → Weekend Prototype

// Zero configuration - starts in memory
const brain = new Brainy()
await brain.init()

// Build your prototype in minutes
// Change nothing when ready to scale

Perfect for: Hackathons, side projects, rapid prototyping, learning AI concepts

👥 Small Team → Production MVP (Thousands of Entities)

// Add persistence - one line
const brain = new Brainy({
  storage: {
    type: 'filesystem',
    path: './brainy-data',
    compression: true  // 60-80% space savings
  }
})

Perfect for: Startups, MVPs, internal tools, team knowledge bases Scale: Thousands to hundreds of thousands of entities Performance: <5ms queries, sub-second imports

🏢 Growing Company → Multi-Million Entity Scale

// Scale to cloud - same API
const brain = new Brainy({
  storage: {
    type: 's3',
    s3Storage: {
      bucketName: 'my-knowledge-base',
      region: 'us-east-1'
    }
  },
  hnsw: { typeAware: true }  // 87% memory reduction
})

Perfect for: SaaS products, e-commerce, content platforms, enterprise apps Scale: Millions of entities Performance: <10ms queries, 12GB memory @ 10M entities Features: Auto-scaling, distributed storage, cost optimization (96% savings)

🌍 Enterprise / Planet Scale → Billion+ Entities

// Billion-scale - STILL the same API
const brain = new Brainy({
  storage: {
    type: 'gcs',
    gcsStorage: { bucketName: 'global-knowledge' }
  },
  hnsw: {
    typeAware: true,
    M: 32,
    efConstruction: 400
  }
})

// Enable intelligent archival
await brain.storage.enableAutoclass({
  terminalStorageClass: 'ARCHIVE'
})

Perfect for: Fortune 500, global platforms, research institutions, government Scale: Billions of entities (tested at 1B+) Performance: 18ms queries @ 1B scale, 50GB memory (87% reduction) Cost: $138k/year → $6k/year with intelligent tiering (96% savings) Features: Sharding, replication, monitoring, enterprise SLAs

🎯 The Point

Start simple. Scale infinitely. Never rewrite.

Most systems force you to choose:

• Simple but doesn't scale (SQLite, Redis)
• Scales but complex (Kubernetes + 7 databases)

Brainy gives you both: Starts simple as SQLite. Scales like Google.

Why Brainy Is Revolutionary

🧠 Triple Intelligence™ — The Impossible Made Possible

The world's first to unify three database paradigms in ONE API:

What You Get	Like Having	But Unified
🔍 Vector Search	Pinecone, Weaviate	Find by meaning
🕸️ Graph Relationships	Neo4j, ArangoDB	Navigate connections
📊 Document Filtering	MongoDB, Elasticsearch	Query metadata

Every other system makes you choose. Brainy does all three together.

Why this matters: Your data isn't just vectors or just documents or just graphs. It's all three at once. A research paper is semantically similar to other papers (vector), written by an author (graph), and published in 2023 (document). Brainy is the only system that understands this.

🎯 31 Noun Types × 40 Verb Types = Universal Protocol

Model any domain with mathematical completeness:

31 Nouns × 40 Verbs × ∞ Metadata = 1,240+ base combinations

Real-world expressiveness:

• Healthcare: Patient → diagnoses → Condition
• Finance: Account → transfers → Transaction
• Manufacturing: Product → assembles → Component
• Education: Student → completes → Course
• YOUR domain → Your types + relationships = Your knowledge graph

→ See the Mathematical Proof

⚡ Zero Configuration Philosophy

We hate configuration files. So we eliminated them.

const brain = new Brainy()  // Auto-detects everything
await brain.init()          // Optimizes for your environment

Brainy automatically:

• Detects optimal storage (memory/filesystem/cloud)
• Configures memory based on available RAM
• Optimizes for containers (Docker/K8s)
• Tunes indexes for your data patterns
• Manages embedding models and caching

You write business logic. Brainy handles infrastructure.

🚀 Instant Fork™ — Git for Databases (v5.0.0)

Clone your entire database in <100ms. Merge back when ready. Full Git-style workflow.

// Fork instantly - Snowflake-style copy-on-write
const experiment = await brain.fork('test-migration')

// Make changes safely in isolation
await experiment.add({ type: 'user', data: { name: 'Test User' } })
await experiment.updateAll({ /* migration logic */ })

// Commit your work
await experiment.commit({ message: 'Add test user', author: 'dev@example.com' })

// Merge back to main with conflict resolution
const result = await brain.merge('test-migration', 'main', {
  strategy: 'last-write-wins'
})

console.log(result)  // { added: 1, modified: 0, conflicts: 0 }

NEW in v5.0.0:

• ✅ fork() - Instant clone in <100ms
• ✅ merge() - Merge with conflict resolution
• ✅ commit() - Snapshot state
• ✅ getHistory() - View commit history
• ✅ checkout(), listBranches() - Full branch management
• ✅ CLI support for all features

How it works: Snowflake-style COW shares HNSW index structures, copying only modified nodes (10-20% memory overhead).

Perfect for: Safe migrations, A/B testing, feature branches, distributed development
