`memory-lancedb` is an official external memory plugin that stores long-term memory in

LanceDB and uses embeddings for recall. It can automatically recall relevant

memories before a model turn and capture important facts after a response.

Use it when you want a local vector database for memory, need an

OpenAI-compatible embedding endpoint, or want to keep a memory database outside

the default built-in memory store.

## Installation

Install `memory-lancedb` before setting `plugins.slots.memory = "memory-lancedb"`:

```bash

openclaw plugins install @openclaw/memory-lancedb

```

The plugin is published to npm and is not bundled into the OpenClaw runtime image.

The installer writes the plugin entry and switches the memory slot when no other

plugin owns it.

<Note>

`memory-lancedb` is an active memory plugin. Enable it by selecting the memory

slot with `plugins.slots.memory = "memory-lancedb"`. Companion plugins such as
