Zep

Zep is a context engineering platform that enables developers to build personalized, fast, and reliable AI agents by assembling the right context from chat history, business data, and user behavior. It provides a unified pipeline that ingests data from multiple sources, builds a temporal context graph that evolves with every interaction, and delivers token-efficient context to agents. Key features include automatic entity extraction and fact invalidation, sub-200ms P95 retrieval latency, and a simple three-line-code API that works with any agent framework. Zep also offers customizable context blocks, support for domain-specific entity models (e.g., sales, support, e-commerce), and enterprise-grade compliance (SOC 2 Type II, HIPAA). The platform is built on an open-source foundation (Graphiti) and offers a free tier with full API access.
