About

What is EverMemOS?

EverMemOS is an open-source project designed to build, evaluate, and integrate long-term memory for self-evolving AI agents. At its core is EverCore, a self-organizing memory operating system inspired by biological imprinting, which extracts, structures, and retrieves long-term knowledge from conversations. The platform also includes HyperMem, a hypergraph-based hierarchical memory architecture. EverMemOS provides evaluation suites like EverMemBench for memory quality and EvoAgentBench for agent self-evolution, allowing users to measure how agents remember, reason, and evolve. It offers various use cases and templates to plug the core memory system into, such as AI companions, code plugins, and interactive demos, making it a comprehensive solution for developing memory-enhanced AI applications.

Best used for

Ideal for developers and data scientists who need to build self-evolving AI agents, integrate persistent long-term memory, and rigorously evaluate agent performance. Especially valuable for creating AI companions, memory-enhanced code plugins, and interactive demos that require agents to remember and learn over time.

FAQs

What is EverCore within EverMemOS?

EverCore is the central long-term memory operating system within EverMemOS. It is designed to extract, structure, and retrieve knowledge from conversations, enabling AI agents to remember, understand, and continuously evolve based on past interactions.

How does EverMemOS help evaluate AI agent memory?

EverMemOS includes evaluation suites like EverMemBench for assessing memory quality (factual recall, reasoning, generalization) and EvoAgentBench for measuring agent self-evolution through longitudinal growth curves, transfer efficiency, and error avoidance.

Can I integrate EverMemOS with my existing AI projects?

Yes, EverMemOS is designed for integration. It provides an API for storing and retrieving memories, and offers various use cases and templates, such as an AI companion or a Claude Code Plugin, to help you plug the memory system into your applications.
