Neurotrace

A hybrid memory library designed for LangChain agents, providing dual-layer memory architecture with short-term buffer memory and long-term hybrid RAG system capabilities.

Overview

Neurotrace provides persistent, intelligent memory for conversational agents that improves over time and enables contextual understanding and recall. It combines vector-based and graph-based RAG (Retrieval Augmented Generation) systems to provide deeper and more accurate contextual reasoning.

🎯 Key Features

• Dual-Layer Memory Architecture

  • Short-term buffer memory for immediate context
  • Long-term hybrid RAG system for persistent storage

• Real-time Processing

  • Real-time recall during conversations
  • Intelligent storage and compression

• Rich Message Structure

  • Custom metadata-rich message formats
  • Support for filtering and semantic tracing

• Hybrid Retrieval System

  • Combined vector and graph-based RAG
  • Enhanced contextual reasoning capabilities

🎯 Target Users

• Developers building AI agents with LangChain
• Researchers exploring memory augmentation in LLMs
• Enterprises deploying context-aware AI assistants

Quick Start

Installation

pip install neurotrace

Complete Example

A complete, runnable example is available in examples/agent_example.py. This example demonstrates:

• Setting up a Neurotrace agent with both short-term and long-term memory
• Configuring vector and graph storage
• Implementing an interactive conversation loop
• Monitoring memory usage

To run the example:

# First set up your environment variables
export NEO4J_URL=bolt://localhost:7687
export NEO4J_USERNAME=neo4j
export NEO4J_PASSWORD=your_password
export GOOGLE_API_KEY=your_google_api_key

# Then run the example
python examples/agent_example.py

Required Environment Variables

NEO4J_URL=bolt://localhost:7687
NEO4J_USERNAME=neo4j
NEO4J_PASSWORD=your_password
GOOGLE_API_KEY=your_google_api_key  # For Gemini LLM

Technical Documentation

Core Schema

The neurotrace.core.schema module defines the fundamental data structures used throughout the project.

Message

The core Message class represents a single message in the system:

from neurotrace.core.schema import Message, MessageMetadata, EmotionTag

message = Message(
    role="user",           # Can be "user", "ai", or "system"
    content="Hello!",      # The message text content
    metadata=MessageMetadata(
        source="chat",
        emotions=EmotionTag(sentiment="positive")
    )
)

Key features of Message:

• Auto-generated UUID for each message
• Automatic timestamp on creation
• Type-safe role validation
• Rich metadata support via MessageMetadata

Message Components

EmotionTag

Represents the emotional context of a message:

from neurotrace.core.schema import EmotionTag

emotion = EmotionTag(
    sentiment="positive",  # Can be "positive", "neutral", or "negative"
    intensity=0.8         # Optional float value indicating intensity
)

MessageMetadata

Contains additional information and context about a message:

from neurotrace.core.schema import MessageMetadata, EmotionTag

metadata = MessageMetadata(
    token_count=150,                    # Number of tokens in the message
    embedding=[0.1, 0.2, 0.3],         # Vector embedding for similarity search
    source="chat",                      # Source: "chat", "web", "api", or "system"
    tags=["important", "follow-up"],    # Custom tags
    thread_id="thread_123",            # Conversation thread identifier
    user_id="user_456",               # Associated user identifier
    related_ids=["msg_789"],          # Related message IDs
    emotions=EmotionTag(sentiment="positive"),  # Emotional context
    compressed=False                   # Compression status
)

Each field in MessageMetadata is optional and provides specific context:

• token_count: Used for tracking token usage
• embedding: Vector representation for similarity search
• source: Indicates message origin
• tags: Custom categorization
• thread_id: Groups messages in conversations
• user_id: Links messages to users
• related_ids: Connects related messages
• emotions: Captures emotional context
• compressed: Indicates if content is compressed
