# Mengram vs LangMem

LangMem is LangChain's memory module for LangGraph agents. Mengram is a standalone memory API that works with any framework — LangChain, CrewAI, OpenAI, or direct API calls.

## What LangMem does well

- Native LangGraph integration — first-class LangChain support
- Thread-scoped and cross-thread memory
- Backed by LangChain team — strong ecosystem alignment
- Memory formed via background processing

## What LangMem doesn't have

- Tightly coupled to LangGraph — harder to use outside LangChain
- No episodic memory (events, decisions)
- No procedural memory (workflows)
- No Cognitive Profile
- No standalone MCP server
- No knowledge graph visualization
