AI agent memory / long-term memory for LLMs
mem0 is an open-source universal memory layer for AI agents that uses LLM extraction and RAG retrieval to give agents persistent, long-term memory across sessions.
Same problem, same approach. Swapping one for another is a config change, not a rewrite.

Choose when you are building agents specifically on Claude and want session-memory injection.
Persistent Context Across Sessions for Every Agent – Captures everything your agent does during sessions, compresses it with AI, and injects relevant context back into future sessions. Works with Claude Code, OpenClaw, Codex, Gemini, Hermes, Copilot, OpenCode + More
These projects were analysed and named mem0 among their alternatives. The relationship is not symmetric — how mem0 rates them is a separate judgement, made when mem0 is analysed in its own right.

Memory and context engine + app that is extremely fast, scalable, and can be run fully locally. The Memory API for the AI era.
calls mem0 “if you need a Python-based memory API that is widely adopted and framework-agnostic, instead of TypeScript and TencentDB-centric.”
TencentDB Agent Memory is a team-level memory hub for AI Agents — turning conversations, docs, and code into four reusable memory assets (Chat Memory, Skill, LLM-Wiki, Code-Graph) that are governed, shared, and equipped across agents and frameworks.

Memori is agent-native memory infrastructure. A LLM-agnostic layer that turns agent execution and conversation into structured, persistent state for production systems. Built for enterprise, Memori works with the data infrastructure you already run, no rip-and-replace, and deploys across managed cloud, single-tenant cloud, VPC, and on-premises.
