# Introduction

> Memory Crystal is a persistent memory layer that helps AI agents remember context, decisions, and workflows across sessions.

> Current release: **v0.8.20**. See the [changelog](/changelog) for what shipped, and use the [uninstall guide](/help/uninstall) when you need a clean rollback.

Imagine your AI helper has a backpack.
Usually, every time you start a new chat, the backpack gets emptied and the helper forgets everything.
Memory Crystal gives the helper a **memory backpack that stays packed**.
It can remember what you were doing, what rules matter, and what you already figured out.

## What this means in practice

Memory Crystal is for people who are tired of repeating themselves to their AI.
It helps when you want your assistant to remember things like:

* the architecture you already chose
* the commands your project uses
* who owns what
* what failed before
* which docs or notes matter for this task

It currently ships as:

* an **OpenClaw plugin**
* an **MCP server** for compatible clients
* a **Convex-backed memory backend**
* a **web product/dashboard**

## How it actually works

At a high level, Memory Crystal does two jobs:

1. **Capture** — it records useful conversational and operational context.
2. **Recall** — it brings back the right memories before the next response or through tools.

The repo is split into major surfaces:

* `plugin/` — OpenClaw plugin and automatic hook-based memory flows
* `convex/` — backend schema, memory logic, HTTP endpoints, Organic Memory
* `mcp-server/` — deprecated stdio/HTTP MCP server
* `packages/mcp-server/` — current Streamable HTTP MCP server
* `apps/web/` — product site, dashboard, install assets, and brand source material
* `apps/docs/` — public Mintlify docs
* `scripts/` — installation, doctor, enable/disable, migration helpers

## A tiny example

Without Memory Crystal:

* you tell the AI “we deploy with Convex and keep product docs in Mintlify”
* tomorrow it forgets

With Memory Crystal:

* that fact can be captured and retrieved again when it matters
* the assistant starts closer to the truth instead of from zero

## Commands / examples

The main public install entrypoint is:

```bash theme={"system"}
curl -fsSL https://memorycrystal.ai/crystal | bash
```
