## 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.**

```javascript
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:**

```javascript
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.

---

## Quick Start

```bash
npm install @soulcraft/brainy
```

### Your First Knowledge Graph (60 seconds)

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

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

// Add knowledge
const jsId = await brain.add({
    data: "JavaScript is a programming language",
    type: NounType.Concept,
    metadata: { category: "language", year: 1995 }
})

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

// Create relationships
await brain.relate({ from: nodeId, to: jsId, type: VerbType.Executes })

// Query with Triple Intelligence
const results = await brain.find({
    query: "JavaScript",                     // 🔍 Vector
    where: { category: "language" },         // 📊 Document
    connected: { from: nodeId, depth: 1 }    // 🕸️ Graph
})
```

**Done.** No configuration. No complexity. Production-ready from day one.

## From Prototype to Planet Scale

**The same API. Zero rewrites. Any scale.**

### 👤 Individual Developer → Weekend Prototype
```javascript
const brain = new Brainy()  // Zero config, starts in memory
await brain.init()
```
**Perfect for:** Hackathons, side projects, prototyping, learning

### 👥 Small Team → Production MVP
```javascript
const brain = new Brainy({
  storage: { type: 'filesystem', path: './data', compression: true }
})
```
**Scale:** Thousands to hundreds of thousands • **Performance:** <5ms queries
**→ [Production Service Architecture](docs/PRODUCTION_SERVICE_ARCHITECTURE.md)** — Singleton patterns, caching, and scaling for Bun/Node.js services

### 🏢 Growing Company → Multi-Million Scale
```javascript
const brain = new Brainy({
  storage: { type: 's3', s3Storage: { bucketName: 'my-kb', region: 'us-east-1' } },
  hnsw: { typeAware: true }  // 87% memory reduction
})
```
**Scale:** Millions of entities • **Performance:** <10ms queries, 12GB @ 10M entities

### 🌍 Enterprise → Billion+ Scale
```javascript
const brain = new Brainy({
  storage: { type: 'gcs', gcsStorage: { bucketName: 'global-kb' } },
  hnsw: { typeAware: true, M: 32, efConstruction: 400 }
})
```
**Scale:** Billions (tested @ 1B+) • **Performance:** 18ms queries, 50GB memory
**Cost:** $138k/year → $6k/year with intelligent tiering (96% savings)

**→ [Capacity Planning Guide](docs/operations/capacity-planning.md)** | **[Cost Optimization](docs/operations/)**

### 🎯 The Point

**Start simple. Scale infinitely. Never rewrite.**

Most systems make you choose: Simple (SQLite) OR Scalable (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.**

### 🎯 **42 Noun Types × 127 Verb Types = Universal Protocol**

Model **any domain** with mathematical completeness:

```
42 Nouns × 127 Verbs × ∞ Metadata = 5,334+ base combinations
Stage 3 CANONICAL: 96-97% coverage of all human knowledge
```

**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](docs/architecture/noun-verb-taxonomy.md)

### ⚡ **Zero Configuration Philosophy**

**We hate configuration files. So we eliminated them.**

```javascript
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.**

### 🚀 **Git-Style Version Control** — Database & Entity Level (v5.0.0+)

**Clone your entire database in <100ms. Track every entity change. Full Git-style workflow.**

```javascript
// 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' })

// Switch to experimental branch to make it active
await brain.checkout('test-migration')

// Time-travel: Query database at any past commit (read-only)
const commits = await brain.getHistory({ limit: 10 })
const snapshot = await brain.asOf(commits[5].id)
const pastResults = await snapshot.find({ query: 'historical data' })
await snapshot.close()

// Entity versioning: Track changes to individual entities (v5.3.0+)
const userId = await brain.add({ type: 'user', data: { name: 'Alice' } })
await brain.versions.save(userId, { tag: 'v1.0', description: 'Initial profile' })

await brain.update(userId, { data: { name: 'Alice Smith', role: 'admin' } })
await brain.versions.save(userId, { tag: 'v2.0', description: 'Added role' })

// Compare versions or restore previous state
const diff = await brain.versions.compare(userId, 1, 2)  // See what changed
await brain.versions.restore(userId, 1)  // Restore v1.0
```

**Database-level version control (v5.0.0):**
- ✅ `fork()` - Instant clone in <100ms
- ✅ `merge()` - Merge with conflict resolution
- ✅ `commit()` - Snapshot state
- ✅ `asOf()` - Time-travel queries (query at any commit)
- ✅ `getHistory()` - View commit history
- ✅ `checkout()`, `listBranches()` - Full branch management
- ✅ CLI support for all features

**Entity-level version control (v5.3.0):**
- ✅ `versions.save()` - Save entity snapshots with tags
- ✅ `versions.restore()` - Restore previous versions
- ✅ `versions.compare()` - Diff between versions
- ✅ `versions.list()` - View version history
- ✅ Automatic deduplication (content-addressable storage)

**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, time-travel debugging, audit trails, document versioning, compliance tracking

## What Can You Build?

**If your app needs to remember, understand, or connect information — Brainy makes it trivial.**

### 🤖 **AI Agents with Perfect Memory**
Give your AI unlimited context that persists forever. Not just chat history — true understanding of relationships, evolution, and meaning over time.

**Examples:** Personal assistants, code assistants, conversational AI, research agents

### 📚 **Living Documentation & Knowledge Bases**
Documentation that understands itself. Auto-links related concepts, detects outdated information, finds connections across your entire knowledge base.

**Examples:** Internal wikis, research platforms, smart documentation, learning systems

### 🔍 **Semantic Search at Any Scale**
Find by meaning, not keywords. Search codebases, research papers, customer data, or media libraries with natural language.

**Examples:** Code search, research platforms, content discovery, recommendation engines

### 🏢 **Enterprise Knowledge Management**
Corporate memory that never forgets. Track every customer interaction, product evolution, and business relationship.

**Examples:** CRM systems, product catalogs, customer intelligence, institutional knowledge

### 🎮 **Rich Interactive Experiences**
NPCs that remember. Characters that persist across stories. Worlds that evolve based on real relationships.

**Examples:** Game worlds, interactive fiction, educational platforms, creative tools

### 🎨 **Content & Media Platforms**
Every asset knows its relationships. Intelligent tagging, similarity-based discovery, and relationship-aware management.

**Examples:** DAM systems, media libraries, writing assistants, content management

**The pattern:** Knowledge that needs to live, connect, and evolve. That's what Brainy was built for.

## Core Features

### 🧠 **Natural Language Queries**

```javascript
// Ask naturally - Brainy understands
await brain.find("recent React components with tests")
await brain.find("JavaScript libraries similar to Vue")

// Or use structured Triple Intelligence queries
await brain.find({
    query: "React",
    where: { type: "library", year: { greaterThan: 2020 } },
    connected: { to: "JavaScript", depth: 2 }
})
```

**→ [See all query methods in API Reference](docs/api/README.md#search--query)**

### 🔍 **Zero-Config Hybrid Search** (v7.7.0)

Automatically combines text (keyword) and semantic (vector) search for optimal results:

```javascript
// Just works - no configuration needed
const results = await brain.find({ query: 'David Smith' })
// Finds exact text matches AND semantically similar content

// Override when needed
await brain.find({ query: 'exact match', searchMode: 'text' })     // Text only
await brain.find({ query: 'AI concepts', searchMode: 'semantic' }) // Semantic only
await brain.find({ query: 'hybrid', hybridAlpha: 0.3 })            // Custom weighting

// Highlight structured content (v7.8.0) — plain text, JSON, HTML, Markdown
const highlights = await brain.highlight({
  query: 'warrior',
  text: entity.data  // Auto-detects TipTap, Slate, Lexical, HTML, Markdown
})
// Each highlight has: text, score, position, matchType, contentCategory
```

**→ [Hybrid Search Documentation](docs/api/README.md#hybrid-search-v770)**

### 🌐 **Virtual Filesystem** — Intelligent File Management

Build file explorers and IDEs that never crash:

```javascript
const vfs = brain.vfs()

// Tree-aware operations prevent infinite recursion
const tree = await vfs.getTreeStructure('/projects', { maxDepth: 3 })

// Semantic file search
const reactFiles = await vfs.search('React components with hooks')
```

**[📖 VFS Quick Start →](docs/vfs/QUICK_START.md)** | **[Common Patterns →](docs/vfs/COMMON_PATTERNS.md)** | **[Neural Extraction →](docs/vfs/NEURAL_EXTRACTION.md)**

### 🚀 **Import Anything** — CSV, Excel, PDF, URLs

```javascript
await brain.import('customers.csv')  // Auto-detects everything
await brain.import('sales-data.xlsx', { excelSheets: ['Q1', 'Q2'] })
await brain.import('research-paper.pdf', { pdfExtractTables: true })
await brain.import('https://api.example.com/data.json')
```

**[📖 Complete Import Guide →](docs/guides/import-anything.md)**

### 🧠 **Neural API** — Advanced Semantic Analysis

```javascript
// Clustering, similarity, outlier detection, visualization
const clusters = await brain.neural.clusters({ algorithm: 'kmeans' })
const similarity = await brain.neural.similar('item1', 'item2')
const outliers = await brain.neural.outliers(0.3)
const vizData = await brain.neural.visualize({ maxNodes: 100 })
```

---

## Framework Integration

## Storage — From Memory to Planet-Scale

### Development → Just Works
```javascript
const brain = new Brainy()  // Memory storage, zero config
```

### Production → Persistence with Compression
```javascript
const brain = new Brainy({
  storage: { type: 'filesystem', path: './data', compression: true }
})
// 60-80% space savings with gzip
```

### Cloud → AWS, GCS, Azure, Cloudflare R2
```javascript
// AWS S3 / Cloudflare R2
const brain = new Brainy({
  storage: {
    type: 's3',
    s3Storage: {
      bucketName: 'my-knowledge-base',
      region: 'us-east-1'
    }
  }
})

// Enable Intelligent-Tiering: 96% cost savings
await brain.storage.enableIntelligentTiering('entities/', 'auto-tier')
```

**Cost optimization at scale:**

| Scale | Standard | With Intelligent Tiering | Annual Savings |
|-------|----------|--------------------------|----------------|
| 5TB | $1,380 | $59 | $1,321 (96%) |
| 50TB | $13,800 | $594 | $13,206 (96%) |
| 500TB | $138,000 | $5,940 | $132,060 (96%) |

**[📖 Full v4.0.0 Changelog →](CHANGELOG.md)** | **[Migration Guide →](docs/MIGRATION-V3-TO-V4.md)** (100% backward compatible)

---

## Requirements

> **Deprecation Notice:** Browser support (OPFS storage, Web Workers, WASM embeddings) is deprecated in v7.10.0 and will be removed in v8.0.0. Brainy v8+ will be server-only (Node.js >= 22, Bun >= 1.3.0). Migrate browser deployments to a server-side API.

**Bun 1.0+** (recommended) or **Node.js 22 LTS**

```bash
# Bun (recommended - best performance, single-binary deployment)
bun install @soulcraft/brainy

# Node.js (fully supported)
npm install @soulcraft/brainy
```

> **Why Bun?** Brainy's Candle WASM engine works seamlessly with `bun --compile` for standalone binary deployment. No external model files, no runtime downloads.

---

## Why Brainy Exists

**The Vision:** Traditional systems force you to choose between vector databases, graph databases, and document stores. You need all three, but combining them is complex and fragile.

**Brainy solved the impossible:** One API. All three paradigms. Any scale.

Like HTTP standardized web communication, **Brainy standardizes knowledge representation.** One protocol that any AI model understands. One system that scales from prototype to planet.
