20 AI agent memory tools to know in 2026, from Mem0 to Graphiti
MaryamMiradi · x · 2026-11-05
Maryam Miradi maps the AI agent memory landscape across five categories: dedicated memory (Mem0, Letta, Cognee, Graphiti), framework memory (LangGraph, LlamaIndex, CrewAI, Agno), vector memory (Qdrant, Weaviate, Milvus, Chroma), graph + state (Zep, Neo4j, Redis, SurrealDB), and specialists (Semantic Kernel, Haystack, AutoGen, FAISS). Key insight: storing every interaction isn't useful memory — production agents need the right fact, at the right time, with the right scope. She may benchmark the leading options next.
