# Get Started with Comfy Agent

> Open Comfy Agent in Comfy Cloud or Comfy Desktop.

## Choose your setup

You need a Comfy account with Agent access.

* **Comfy Cloud:** [Sign in to Cloud](https://cloud.comfy.org). No local installation is needed.
* **Comfy Desktop:** Follow the [Desktop installation guide](/installation/desktop/overview), then sign in. For an existing installation, follow [Update ComfyUI](/installation/update_comfyui).

## Make your first image

### Open the Agent

Open a blank workflow, then select **Ask Comfy Agent** in the workflow bar. Read and accept the consent notice if prompted. Use **Choose a workflow** in the Agent panel to select the blank workflow.

### Build a workflow

Send this message:

> Build a text-to-image workflow for a red sneaker on a neutral gray background. Use an available model and include a Save Image node. Check the workflow for errors, but don't run it yet.

The Agent builds the workflow on the canvas, fills in the prompt and model settings, and checks the node connections and required inputs. You should see a connected workflow ending in a **Save Image** node.

If the Agent reports a missing model or file, supply it or ask for an alternative available in your installation. Ask it to check the workflow again before continuing.

### Generate the image

Open **Run permissions** next to the message box, choose **Ask before a workflow runs**, and select **Save changes** if you changed the setting.

Send “Run this workflow.” When the Agent asks for approval, select **Run**. Select **Cancel** instead if you do not want to start that run.

When generation finishes, the Agent returns the output in the conversation. The image also appears in the **Save Image** node. Right-click the image there to save it to your computer.

### Make a change

Send “Change the background to white and keep the model and other settings.” The Agent updates the existing workflow. Ask it to run again to compare the result.

## Troubleshooting

### The Agent button is missing

Sign in to your Comfy account. In Comfy Desktop, [update the application](/installation/update_comfyui) and restart it. If the button is still missing, check your account's Agent access with [support](/support/contact-support).

### The Agent cannot edit the workflow I expected

Choose the intended workflow in the Agent panel, then send your message again. See [Choose which workflow to edit](/agent-tools/in-app-agent#choose-which-workflow-to-edit).

### The Agent asks for an input

Select **Attach a file** or drag the requested file into the message box, then ask the Agent to continue.

### I cannot find a local conversation in Cloud

Local and Cloud history are separate. See [Data and privacy](/agent-tools/in-app-agent-data-privacy#chat-history-and-sync).
