Long-term memory system for AI conversations - similar to Mem0/Supermemory

ContextMemory

Long-term memory system for AI conversations - similar to Mem0/Supermemory.

ContextMemory extracts, stores, and retrieves important facts from conversations, enabling AI assistants to remember user preferences, context, and history across sessions.

Installation

pip install contextmemory

Quick Start

1. Configure

Option A: Programmatic (Recommended)

from contextmemory import configure

configure(
    openai_api_key="sk-...",  # Required
    database_url="postgresql://...",  # Optional - defaults to SQLite
)

Option B: Environment Variables

export OPENAI_API_KEY="sk-..."
export DATABASE_URL="postgresql://..."  # Optional

2. Initialize Database

from contextmemory import create_table

create_table()  # Creates all required tables

3. Use Memory System

from contextmemory import Memory, SessionLocal

# Create session and memory instance
db = SessionLocal()
memory = Memory(db)

# Add memories from a conversation
messages = [
    {"role": "user", "content": "Hi, I'm John and I love Python programming"},
    {"role": "assistant", "content": "Nice to meet you John! Python is great."},
]
memory.add(messages=messages, conversation_id=1)

# Search memories
results = memory.search(
    query="What programming language does the user like?",
    conversation_id=1,
    limit=5
)
print(results)
# {'query': '...', 'results': [{'memory_id': 1, 'memory': 'User loves Python programming', 'score': 0.89}]}

# Update a memory
memory.update(memory_id=1, text="User is an expert Python developer")

# Delete a memory
memory.delete(memory_id=1)

Features

• Automatic Memory Extraction: Uses LLM to extract important facts from conversations
• Semantic Search: Find relevant memories using embedding-based similarity
• Memory Deduplication: Automatically updates or removes duplicate memories
• Flexible Storage: SQLite (default) or PostgreSQL
• Easy Configuration: Programmatic or environment variable setup

Configuration Options

Parameter	Required	Default	Description
openai_api_key	Yes	-	Your OpenAI API key
database_url	No	~/.contextmemory/memory.db	Database connection URL
debug	No	False	Enable debug logging

Database Support

• SQLite (default): No additional setup required
• PostgreSQL: Install with pip install contextmemory[postgres]
