🧠 Brainy 2.0 API Reference

The definitive API documentation for Brainy 2.0
Clean • Powerful • Zero-Configuration

Quick Start

import { BrainyData } from '@soulcraft/brainy'

const brain = new BrainyData()  // Zero config!
await brain.init()

// Add data (text auto-embeds!)
await brain.addNoun('The future of AI is here', 'content')

// Search with Triple Intelligence
const results = await brain.find({
  like: 'artificial intelligence',
  where: { year: { greaterThan: 2020 } },
  connected: { via: 'references' }
})

Core Concepts

🧬 Nouns

Vectors with metadata - the fundamental data unit in Brainy.

🔗 Verbs

Relationships between nouns - the connections that create knowledge graphs.

🧠 Triple Intelligence

Vector search + Graph traversal + Metadata filtering in one unified query.

API Reference

Data Operations

Nouns (Vectors with Metadata)

addNoun(dataOrVector, metadata?)

Add a single noun to the database.

• dataOrVector: string | number[] - Text (auto-embeds) or pre-computed vector
• metadata: object - Associated metadata
• Returns: Promise<string> - The noun's ID

getNoun(id)

Retrieve a noun by ID.

• id: string - The noun's ID
• Returns: Promise<VectorDocument | null>

updateNoun(id, dataOrVector?, metadata?)

Update an existing noun.

• id: string - The noun's ID
• dataOrVector: string | number[] - New data/vector (optional)
• metadata: object - New metadata (optional)
• Returns: Promise<void>

deleteNoun(id)

Delete a noun.

• id: string - The noun's ID
• Returns: Promise<boolean>

getNouns(options)

Get multiple nouns (unified method).

• options: Can be:
  • string[] - Array of IDs
  • {where: object} - Metadata filter
  • {limit: number, offset: number} - Pagination
• Returns: Promise<VectorDocument[]>

Verbs (Relationships)

addVerb(source, target, type, metadata?)

Create a relationship between nouns.

• source: string - Source noun ID
• target: string - Target noun ID
• type: string - Relationship type
• metadata: object - Relationship metadata (optional)
• Returns: Promise<string> - The verb's ID

getVerbsBySource(sourceId)

Get all outgoing relationships.

• sourceId: string - Source noun ID
• Returns: Promise<Verb[]>

getVerbsByTarget(targetId)

Get all incoming relationships.

• targetId: string - Target noun ID

---

Search Operations

search(query, k?)

Simple vector similarity search.

• query: string | number[] - Text or vector
• k: number - Number of results (default: 10)
• Returns: Promise<SearchResult[]>

💡 This is equivalent to: find({like: query, limit: k})

find(query) - Triple Intelligence 🧠

The ultimate search method combining vector, graph, and metadata search.

find({
  // Vector similarity
  like: 'text query' | vector | {id: 'noun-id'},
  
  // Metadata filtering (Brainy operators)
  where: {
    field: value,                    // Exact match
    field: {
      equals: value,
      greaterThan: value,
      lessThan: value,
      greaterEqual: value,
      lessEqual: value,
      oneOf: [val1, val2],          // In array
      notOneOf: [val1, val2],       // Not in array
      contains: value,              // Array/string contains
      startsWith: value,
      endsWith: value,
      matches: /pattern/,           // Pattern match
      between: [min, max]
    }
  },
  
  // Graph traversal
  connected: {
    to: 'noun-id',                  // Target noun
    from: 'noun-id',                // Source noun  
    via: 'relationship-type',       // Relationship type
    depth: 2                        // Traversal depth
  },
  
  // Control
  limit: 10,                        // Max results
  offset: 0,                        // Skip results
  explain: false                    // Include explanation
})

Examples

Basic Usage

// Add data
const id = await brain.addNoun('Quantum computing breakthrough', {
  category: 'technology',
  year: 2024,
  importance: 'high'
})

// Simple search
const results = await brain.search('quantum physics', 5)

// Complex query with Triple Intelligence
const articles = await brain.find({
  like: 'quantum computing',
  where: {
    year: { greaterThan: 2022 },
    importance: { oneOf: ['high', 'critical'] }
  },
  connected: {
    via: 'references',
    depth: 2
  },
  limit: 10
})

Creating Knowledge Graphs

// Add entities
const ai = await brain.addNoun('Artificial Intelligence', 'concept')
const ml = await brain.addNoun('Machine Learning', 'concept')
const dl = await brain.addNoun('Deep Learning', 'concept')

// Create relationships
await brain.addVerb(ml, ai, 'subset_of')
await brain.addVerb(dl, ml, 'subset_of')
await brain.addVerb(dl, ai, 'enables')

// Traverse the graph
const aiEcosystem = await brain.find({
  connected: { from: ai, depth: 3 }
})

Using Neural Features

// Find similar concepts
const similarity = await brain.neural.similar(
  'renewable energy',
  'sustainable power'
)

// Auto-cluster documents
const clusters = await brain.neural.clusters({
  method: 'kmeans',
  k: 5
})

// Generate visualization
const vizData = await brain.neural.visualize({
  maxNodes: 200,
  algorithm: 'force',
  dimensions: 3
})
// Use vizData with D3.js, Cytoscape, etc.
