Overview

mem9 is a security-tested data-ai skill for Claude AI, providing persistent cloud memory for OpenClaw agents. It allows users to store and recall long-term memory across sessions, devices, or restarts. The plugin connects to a cloud memory space identified by an API key, which is used to reconnect the user to the same memory space. mem9 is suitable for users who want to persist or manage long-term memory, such as remembering user preferences, project context, or important decisions. The skill should not be used for temporary conversation context or one-off tasks that do not require long-term memory.

Q&A

When should I avoid using mem9 for a task?

Do not use mem9 for temporary conversation context or one‑off tasks that don’t require long‑term storage, as it is designed for persistent memory across sessions and devices.

Asked by Omar Haddad · Aug 15, 2025

Is mem9 suitable for multiple agents or workflows to share data?

mem9 allows multiple OpenClaw agents or workflows to connect to the same memory space using the shared API key, enabling collaborative long‑term storage.

Asked by Dara Fitzgerald · Jul 27, 2025

Can I bring existing OpenClaw memory files into mem9?

Yes, mem9 supports importing existing OpenClaw memory files so you can migrate prior session data into the persistent cloud memory.

Asked by Liam O’Connor · Jul 17, 2025

How does mem9 authenticate access to the cloud memory?

mem9 uses an API key that identifies a specific cloud memory space; you must supply this key in the OpenClaw plugin configuration to reconnect to the same memory store.
