About Zep

Zep is a memory layer for AI agents. It helps developers and teams building AI assistants create fast, accurate, and personalized agents by systematically engineering relevant context from chat history and business data.

Key Features

In practice, Zep tackles the challenge of keeping agents up-to-date and context-aware across conversations by combining memory with structured data, so you can trust answers to reflect what matters for a given user or task:

Agent Memory

Stores and retrieves user-specific context and conversation history to maintain continuity across interactions and improve response relevance

Graph RAG

Uses temporal knowledge graphs to organize data and support retrieval-augmented generation for more informed answers

Context Assembly

Gathers relevant information from chat history, documents, and databases to form context for each interaction

Context Engineering

Dynamically integrates user preferences, conversation history, and business data to assemble reliable, task-focused context for LLMs

Summary

Best for ML engineers, product teams building AI assistants, and customer-support teams.
