mem9

Introduction

mem9 is an infinite memory infrastructure built specifically for OpenClaw, focused on delivering persistent memory capabilities for AI agents. The platform solves the problem of agents losing context between sessions through cloud-based memory storage, enabling memory persistence and sharing across sessions, devices, and tools.

Key Features

• Instant persistent storage with hybrid search combining keyword and vector retrieval
• Multi-agent memory sharing for collaborative environments
• Support for OpenClaw, Claude Code, OpenCode, and other platforms
• Lifecycle hooks for automatic memory injection
• Memory import/export, visual management, and secure backup capabilities
• Recall past conversations and reuse learned knowledge across sessions

Highlights

• Purpose-built memory infrastructure for OpenClaw with out-of-the-box hybrid search
• Keyword search works immediately with no configuration, automatically upgrading to vector-plus-keyword hybrid search
• Memory persists with agents across sessions, devices, and tools
• Apache-2.0 open-source license with self-hosting options
• Enterprise-grade encryption, access control, and audit capabilities

Who It's For

mem9 is designed for OpenClaw users, AI agent developers, multi-agent collaboration teams, and technical professionals who need persistent agent memory. It is especially well suited for building long-running agent applications, scenarios that require maintaining context across sessions, and collaborative environments where multiple agents need to share knowledge.
