Downloading a plugin is optional. Members don't need it: once Tilt Base is connected, their AI finds and retrieves every skill your organisation publishes. A download adds a plugin to your AI platform as well, so the platform can start one of its skills on its own when a request matches it.
## What a download holds
A download holds a small launcher for each skill: its name, its description and where to find it in Tilt Base, but none of the skill itself. Each launcher retrieves the skill's live version from Tilt Base, so members still get your latest published version on every request.
## Download a plugin
1. In Tilt Base, open **Plugins** and select **Download** on the plugin. To download an earlier version, open the plugin's **Versions** page.
2. Choose **Claude**, **ChatGPT** or **Microsoft Copilot**. Each download includes that platform's upload steps.
To get every published plugin at once, select **Download all** on **Plugins**. The ZIP holds one upload ZIP for each plugin, and each platform takes one plugin per upload.
## Claude
On Team and Enterprise plans, an Owner adds the plugin for the organisation.
1. In Claude, open **Organization settings › Plugins & skills**.
2. Select **Add › Upload a plugin** and choose the ZIP.
3. Set the plugin's availability for members.
For a newer version, open the plugin in Claude and select **Upload new version**.
<callout icon="ℹ️">
	**The plugin does not add the connection.** Tilt Base must also be added under **Organization settings › Connectors**, as described in [Claude](https://tilt.legal/docs/tilt-base/claude).
</callout>
## ChatGPT
1. In ChatGPT, open the **Admin console** and select your workspace.
2. Open **Plugins** and select **Add › Upload plugin**, then choose the plugin's ZIP. Upload each plugin separately.
For a newer version, open the plugin and select **Upload new version**.
<callout icon="ℹ️">
	**Uploaded plugins run in the desktop app.** A downloaded plugin carries its own Tilt Base connection, and ChatGPT currently runs uploaded plugins that include a connection only in the ChatGPT desktop app.
</callout>
## Microsoft Copilot
A Global Administrator or AI Administrator of your Microsoft 365 organisation adds the plugin.
1. In the [Microsoft 365 admin center](https://admin.microsoft.com), open **Agents › Tools › Registry** and select **Upload**. Choose the plugin's ZIP.
2. Review what it adds: the Tilt Base server with its tools, and your skills.
3. Choose who gets it, **All users** or **Specific users or groups**, and select **Install**.
A newer version keeps the same app ID, so uploading it updates the plugin.
<callout icon="⚠️">
	**Give each member only one plugin that includes Tilt Base.** A downloaded plugin includes the Tilt Base connection, so it takes the place of the Tilt Base connection package. Copilot turns Tilt Base off for a member who has two plugins that include it, so uninstall the connection package for members who get a downloaded plugin, and give each member only one downloaded plugin.
</callout>
<callout icon="ℹ️">
	**Copilot has plugin limits.** Copilot accepts up to 20 skills in a plugin, each with up to 20 supporting files of 5 MB each and 10 MB in total. If a plugin is over a limit, Tilt Base says so when you download it; split it into smaller plugins.

## Keeping downloads up to date
Launchers always retrieve the live version, so you need to upload a new download only when you add, remove or rename skills, or change a skill's description, including when a new Tilt release changes one. Every other change reaches members through Tilt Base as soon as it is published.
Your AI platform recognises a plugin by its address, which follows the plugin's name. Renaming a plugin changes its address, so the next download installs as a separate plugin rather than replacing the old one. Remove the old plugin from your AI platform, then upload the new download.
