Mem0 — Memory Layer for AI Applications

What is Mem0?

Mem0 (pronounced "memo") is a memory layer for AI applications. It automatically extracts, stores, and retrieves relevant memories from conversations — giving AI agents persistent context across sessions without manual prompt engineering.

Answer-Ready: Mem0 is a memory infrastructure for AI apps that stores user preferences, facts, and context across sessions, enabling personalized AI experiences with simple add/search APIs.

Core Features

1. Automatic Memory Extraction

Mem0 identifies and stores key facts from conversations:

m.add("I'm allergic to peanuts and I live in SF", user_id="bob")
# Stores: ["Allergic to peanuts", "Lives in San Francisco"]

2. Multi-Level Memory

# User-level: personal preferences
m.add("Dark mode preferred", user_id="alice")

# Agent-level: learned behaviors
m.add("Always check tests before committing", agent_id="dev-bot")

# Session-level: conversation context
m.add("Working on the auth refactor", user_id="alice", run_id="session-42")

3. Memory Management

# Get all memories for a user
all_memories = m.get_all(user_id="alice")

# Update a specific memory
m.update(memory_id="mem-123", data="Prefers dark mode in all apps")

# Delete
m.delete(memory_id="mem-123")

# Memory history
history = m.history(memory_id="mem-123")

4. Graph Memory (Beta)

Store relationships between entities:

from mem0 import Memory

config = {"graph_store": {"provider": "neo4j", "config": {...}}}
m = Memory.from_config(config)

m.add("Alice manages the payments team", user_id="org")
# Creates: Alice --manages--> Payments Team

5. Platform Integrations

# With OpenAI
from mem0 import MemoryClient
client = MemoryClient(api_key="mem0-key")

# With LangChain
from langchain.memory import Mem0Memory
memory = Mem0Memory(mem0_api_key="...")

FAQ

Q: Where are memories stored? A: Local mode uses Qdrant (embedded). Cloud mode uses Mem0 managed infra.

Q: How is it different from RAG? A: RAG retrieves from static documents. Mem0 learns and updates from conversations dynamically.

Q: Is it free? A: Open-source for self-hosting. Cloud platform has a free tier.
