# Connect Anthropic
Nected AI Copilot uses Claude by default and includes a limited numbers(3) of free generations. To use Copilot beyond the free limit, or to use your own Claude model, you need to connect your own Anthropic API key.
Once connected, Copilot will use your selected Claude model for all chats in your workspace — generating Rules and Workflows from your prompts or PRDs.
There are two ways to connect your Anthropic API key: directly from the **Home page (Copilot chat window)** or from the **Workspace settings page**.
### Method 1: Connect or Change from the Home Page
This is the quickest way to connect your model — right from where you use Copilot.
#### If no model is connected yet
**Step 1:** From the **Home** page, look at the **Nected AI Copilot** chat window. If no model is connected, you'll see a prompt such as **"Connect your own model."**
{% hint style="info" %}
**You can generate up to 3 solutions for free, without connecting your own model.**
{% endhint %}
**Step 2:** Click **Connect your own model**. This opens the **Connect Anthropic** modal.
**Step 3:** In the modal:
* Enter your **API key** in the **API KEY (Encrypted)** field
* From the **Select Model** dropdown, choose the Claude model you want to use (for example, Claude Opus 4.7, Claude Sonnet 4.6, or Claude Haiku 4.5)
**Step 4:** Click **Connect**.
Once connected, the chat window will show your selected model along with a **Connected** status and a **Change** option.
#### If a model is already connected
**Step 1:** In the Copilot chat window, click **Change** (shown next to your connected model, for example **"Claude Sonnet 4.6 · Connected · Change"**). This opens the **Update Anthropic** modal.
**Step 2:** In the **Update Anthropic** modal, you can:
* Update the **API key**
* Remove the existing key using the **Remove** option
* Select a different model from the **Select Model** dropdown
**Step 3:** Click **Update** to save your changes, or **Cancel** to close without saving.

### Method 2: Connect or Change from the Workspace Settings Page
Use this method if you prefer to manage your AI provider from your workspace settings, or if you're setting things up before opening Copilot for the first time.
**Step 1:** From the left navigation, go to **Settings > Workspace**.
**Step 2:** Scroll down to the **Connect Anthropic** section.
**Step 3:** Click **+ Connect**. This opens the **Connect Anthropic** modal.
**Step 4:** In the modal:
* Enter your **API key** in the **API KEY (Encrypted)** field
* From the **Select Model** dropdown, choose the Claude model you want to use (for example, Claude Opus 4.7, Claude Sonnet 4.6, or Claude Haiku 4.5)
**Step 5:** Click **Connect**.
**Step 6:** Click **Save** at the bottom of the Workspace settings page to apply the changes.
Once saved, your API key is stored encrypted, and the selected model is shown alongside the **Remove** option.
**Changing the model:** To switch to a different model later, click the **Select Model** dropdown in this section and choose a new model, then click **Save**.
{% hint style="success" %}
For users who are using Nected in Self-Hosted mode, they can also connect their Anthropic API key from the workspace settings page.
{% endhint %}
### After Setup
Once your API key and model are configured (via either method), go back to the **Home** page. The Nected AI Copilot chat window will show your connected model, and you can start chatting to create Rules and Workflows based on your prompts or PRDs.
{% hint style="info" %}
**Recommendation:** Nected's Rules and Workflows are optimized for Claude. Use a Claude-based model for the best results.
{% endhint %}
