# Remina

**All-in-One Agentic Memory Framework**

Remina is the complete memory layer for AI agents and applications. Choose between **vector memory** for simple recall or **graph memory** for complex relationship reasoning — with pluggable infrastructure that fits your stack.

```python
from remina import Memory, GraphMemory

# Vector Memory — flat facts with semantic search
memory = Memory()
memory.add("I'm John, I work at Google.", user_id="john")
results = memory.search("Where does John work?", user_id="john")

# Graph Memory — entities and relationships
graph = GraphMemory({"graph_store": {"uri": "bolt://localhost:7687"}})
graph.add("I'm John, I work at Google as a Python developer.", user_id="john")
# Extracts: John (person) → works_at → Google (company)
#           John (person) → uses → Python (technology)
```

## Why Remina

AI agents without persistent memory accumulate technical debt: lost context, repeated user friction, degraded personalization. Remina addresses this at the infrastructure layer with **two memory paradigms**:

| | Vector Memory | Graph Memory |
|---|---|---|
| **Data Model** | Flat facts + embeddings | Entities + Relationships |
| **Storage** | Qdrant, Pinecone, Chroma | Neo4j |
| **Search** | Semantic similarity | Graph traversal + semantic |
| **Best For** | Simple Q&A, preferences | Complex relationships, reasoning |

**Core capabilities:**

- **Automatic fact extraction** — LLM-powered extraction from conversations
- **Entity & relationship extraction** — Build knowledge graphs automatically
- **Hybrid retrieval** — Vector similarity + temporal decay + importance weighting
- **Graph traversal** — Find connected entities through relationships
- **Deduplication** — Similarity-based duplicate prevention
- **Pluggable architecture** — Swap storage, vectors, embeddings, and LLM providers

## Installation

```bash
pip install remina

# With specific providers
pip install remina[openai,qdrant,neo4j]
```

## Quick Start

### Vector Memory

Best for simple fact storage and retrieval.

```python
from remina import Memory

memory = Memory()

# Extract facts from conversation
memory.add(
    messages=[
        {"role": "user", "content": "I just moved to Seattle"},
        {"role": "assistant", "content": "How do you like it?"},
        {"role": "user", "content": "Great city, but the rain takes adjustment"}
    ],
    user_id="user_123"
)
# Extracts: ["Lives in Seattle", "Likes Seattle", "Rain requires adjustment"]

# Semantic search
results = memory.search("Where does the user live?", user_id="user_123")

memory.close()
```

### Graph Memory

Best for complex relationships and multi-hop reasoning.

```bash
# Start Neo4j first
docker compose up neo4j -d
```

```python
from remina import GraphMemory

graph = GraphMemory({
    "graph_store": {
        "uri": "bolt://localhost:7687",
        "password": "remina123",
    },
    "embedder": {"provider": "openai"},
    "llm": {"provider": "openai"},
})

# Extract entities and relationships
result = graph.add(
    messages="I'm Alex, I work at Google as a Python developer. Sarah is my colleague.",
    user_id="user_123",
)
# Entities: Alex (person), Google (company), Python (technology), Sarah (person)
# Relationships: Alex works_at Google, Alex uses Python, Sarah works_at Google

# Search facts
results = graph.search("Where does Alex work?", user_id="user_123")
# → [{"fact": "Alex works at Google", "score": 0.95}]

# Get entity with all relationships
entity = graph.get_entity(entity_id="...")
# → {"entity": {...}, "relationships": [...]}

# Traverse the graph
related = graph.get_related(entity_id="alex_id", hops=2)
# → Connected entities within 2 hops

graph.close()
```

## Async API

Both memory types support async operations:

```python
from remina import AsyncMemory, AsyncGraphMemory
import asyncio

async def main():
    # Vector memory
    memory = AsyncMemory()
    await memory.add("I prefer dark mode", user_id="user_123")
    await memory.close()
    
    # Graph memory
    graph = AsyncGraphMemory({...})
    await graph.add("I'm John from Google", user_id="user_123")
    await graph.close()

asyncio.run(main())
```

## Configuration

### Vector Memory

```python
config = {
    "llm": {"provider": "openai", "config": {"model": "gpt-4o-mini"}},
    "embedder": {"provider": "openai", "config": {"model": "text-embedding-3-small"}},
    "vector_store": {"provider": "qdrant", "config": {"url": "http://localhost:6333"}},
    "storage": {"provider": "postgres", "config": {"host": "localhost", "database": "remina"}},
    "cache": {"redis_url": "redis://localhost:6379", "enabled": True},
}
memory = Memory(config)
```

### Graph Memory

```python
config = {
    "graph_store": {
        "provider": "neo4j",
        "uri": "bolt://localhost:7687",
        "user": "neo4j",
        "password": "password",
    },
    "embedder": {"provider": "openai"},
    "llm": {"provider": "openai"},
    "max_entities_per_message": 10,
    "max_relationships_per_message": 15,
}
graph = GraphMemory(config)
```
