Zep

aid: zep
name: Zep
description: Zep is a context engineering and agent memory platform that assembles relevant context from chat history, business
  data, and user interactions for AI agents. It builds a temporal knowledge graph per user that evolves as new facts arrive,
  automatically extracts entities, and invalidates facts that are superseded. Zep exposes a Graph RAG layer with customizable
  context blocks for fast personalization. The platform offers Cloud and self-hosted community editions with Python, TypeScript,
  and Go SDKs and integrations with LangChain, LangGraph, LlamaIndex, CrewAI, and AutoGen. Zep targets sub-200ms p95 retrieval
  latency and is SOC 2 Type II and HIPAA aligned for enterprise deployments.
