 <PolicyExample policy="AIChatbot" />
 
+### Setting your organization's chat provider as the default
+
+This example adds a company-approved chatbot next to the built-in providers and selects it for users who haven't already picked one.
+`Default` must match the provider's `name`, not its `id`:
+
+```json
+{
+  "policies": {
+    "AIChatbot": {
+      "Providers": {
+        "Add": [
+          {
+            "url": "https://ai.example.com",
+            "name": "Example AI",
+            "id": "example-ai",
+            "iconUrl": "https://ai.example.com/icon.png"
+          }
+        ],
+        "Default": "Example AI"
+      }
+    }
+  }
+}
+```
+
+### Using on-device models
+
+If you run a chatbot on each device, add it as a custom provider so prompts and page content don't leave the device.
+Firefox opens the provider's `url` as a web page in the sidebar and passes prompts in the `q` query parameter, so the server must provide a chat web interface, not just an inference API.
+It must also process requests itself rather than forwarding them to an external service.
+Setting `localhost` to `true` in `BuiltIn` doesn't show the built-in localhost provider, so use `Add` with the address your server listens on.
+Make sure the server is installed and running on every device that receives this policy.
+Another application listening on that port could receive users' prompts.
+This example also removes the built-in cloud providers so users can't choose one instead:
+
+```json
+{
+  "policies": {
+    "AIChatbot": {
+      "Providers": {
+        "Add": [
+          {
+            "url": "http://localhost:8080",
+            "name": "Local model",
+            "id": "local-model"
+          }
+        ],
+        "BuiltIn": {
+          "Anthropic Claude": false,
+          "ChatGPT": false,
+          "Copilot": false,
+          "Google Gemini": false,
+          "HuggingChat": false,
+          "Mistral Vibe": false
+        },
+        "Default": "Local model"
+      }
+    }
+  }
+}
+```
+
+### Turning off prompt suggestions
+
+This example removes the built-in prompts, such as Summarize and Explain, and the prompt shortcut that appears when users select text on a page.
+Users can still type their own prompts in the chatbot in the sidebar:
+
+```json
+{
+  "policies": {
+    "AIChatbot": {
+      "Prompts": {
+        "Enabled": false
+      }
+    }
+  }
+}
+```
