Zep is an AI agent memory platform that assembles context from chat history, business data, and user behavior to build personalized and reliable agents.

Zep provides an end-to-end context engineering platform for AI agents. It connects various data sources like chat messages, JSON business data, and documents, then automatically extracts entities, relationships, and facts to construct a temporal context graph. This graph evolves with every interaction, invalidating old facts as new ones emerge. The platform is designed to retrieve relevant context efficiently and format it for Large Language Models (LLMs), ensuring token efficiency. It supports real-time applications like voice and video agents with low latency retrieval. Zep aims to solve the problem of AI agents failing due to a lack of comprehensive and up-to-date context, moving beyond simple chat memory or static RAG systems.
