# Tools library (https://docs.fuser.studio/docs/tools/library)

Build a tool once and reuse it everywhere. Each successful build and edit is
saved to your Tools library automatically; there's no save button.

## Open the library [#open-the-library]

Click
**Library** in the left sidebar, then choose the **Tools** tab. It has two
views:

* **My Tools** — every tool you can use, newest first.
* **Archived** — tools that have been archived.

Each card shows the tool's name, a **Live** or **Cloud** badge, and its
version, such as **v2**. Hover a card to see the request the tool was first
built from.

## Who sees your tools [#who-sees-your-tools]

The library follows the workspace of the project you have open, like
[recipes](https://docs.fuser.studio/docs/recipes.md).

| Workspace                                  | Who sees its tools                                          |
| ------------------------------------------ | ----------------------------------------------------------- |
| Your personal workspace                    | Only you.                                                   |
| A [team workspace](https://docs.fuser.studio/docs/teams/workspaces.md) | Everyone in the workspace, including tools teammates build. |

A tool built in a team project is saved to that team's library, not your
personal one.

## Place a tool [#place-a-tool]

* **Click** a card to place the tool in the middle of your view. The panel
  closes so you can start wiring.
* **Drag** a card onto the canvas to place it where you drop it.

The placed tool is ready right away, with the same inputs and controls as
when it was built. Wire in an input and a Live tool runs immediately.

## Versions [#versions]

When you [edit a tool](https://docs.fuser.studio/docs/tools/editing.md), the new version appears as its
own card, numbered one higher, such as **v2** next to **v1**. Both stay in
the library, so you can place whichever you need.

## Archive and restore [#archive-and-restore]

Hover a card and click
**Archive tool**, then confirm with **Archive**. The tool moves to
**Archived**.

<div className="mx-auto max-w-lg">
  ![The Archive tool? dialog explaining that copies on canvases keep working](/tools-archive-dialog.png)
</div>

Archiving only hides the tool from the library. Copies already on your
canvases keep working.

To bring it back, open **Archived** and click the card, or hover it and click
**Restore tool** .

> [!NOTE] Archiving in a team workspace
>
> Archiving a team tool hides it for everyone in the workspace. The person who
> built it, or a workspace owner or admin, can archive and restore it.
