# Twin Memory

> Everything your digital twin remembers between conversations—what it picks up on its own, and what your whole organization shares.

Your **Digital Twin** is the assistant you talk to. **Twin Memory** is what it remembers between
those conversations, so you don't have to repeat yourself.

Twin Memory has two parts:

<CardGroup cols={2}>
  <Card title="Long-term Memory" icon="brain">
    Things your twin notices and keeps on its own, from your conversations
  </Card>

  <Card title="Shared Memory" icon="users" href="/mdx/user-guide/memory/shared-memory">
    Information everyone using the same twin can draw on
  </Card>
</CardGroup>

<Note>
  Twin Memory is **additional**. Your [User Memory](/mdx/user-guide/memory/user-memory) and
  [Shared Memory](/mdx/user-guide/memory/shared-memory) keep working exactly as before — nothing
  you have saved goes away, and nothing you already do changes.
</Note>

## Long-term Memory — what your twin keeps on its own

Most assistants forget everything the moment a conversation ends. With Long-term Memory switched
on, yours doesn't: when something in a conversation genuinely changes how it should help you
later, it keeps that.

You don't have to ask. There's no "save this" button to remember to press. If you *do* ask —
"remember that I prefer metric units" — it saves that too, and confirms it.

Most exchanges leave nothing behind. It keeps what matters, not a transcript.

### You always see what it saved

Every time your twin stores something, a small **receipt** appears in the conversation naming
what it saved. Click it to see the detail.

If you ask for something to be kept confidential — or your twin judges it so on its own — the
receipt says a memory was saved without showing the content, and you have to click **Reveal** to
see it. Saying so yourself always counts: if you call something confidential, private, or secret,
your twin treats it that way regardless of how it would have classified it. It will use the memory
when your question genuinely calls for it, and won't bring it up unprompted in unrelated
conversation.

### Managing what it remembers

Everything lives in **Settings → Memory**, where you can:

* **Browse and search** everything your twin has stored
* **Correct** anything it got wrong or worded badly
* **Export** the whole lot as a file, including anything confidential
* **Delete** any memory permanently

<Warning>
  Deleting is permanent. A deleted memory is gone and cannot be restored. If you want it back,
  tell your twin again.
</Warning>

## Shared Memory — what your organization shares

The second half of Twin Memory is the information everyone using the same Digital Twin can draw
on: opening hours, policies, key contacts, anything the whole team benefits from.

This works exactly as it always has — see [Shared Memory](/mdx/user-guide/memory/shared-memory)
for the full picture.

## Availability

Long-term Memory is switched on per Digital Twin by whoever administers it. Some organizations
enable it for everyone, some only for administrators, and some leave it off entirely. If you
don't see a **Long-term Memory** section under Settings → Memory, it isn't enabled for you.

Where it is available, you can still choose for yourself. **Settings → Memory** lets you pick
whether your twin builds long-term memories on its own, or sticks to only the facts you save by
hand.

<Note>
  Turning it off doesn't delete anything. Your existing memories stay, and stay manageable in
  Settings — your twin just stops adding new ones on its own.
