The Knouds canvas lets you wire AI models together visually. In this guide you will build a simple image generation pipeline: a text prompt goes in, a generated image comes out. By the end you will have a saved, runnable workflow and a clear mental model for building more complex pipelines.
Choose your workflow name carefully before you create it. The name is converted into a URL slug at creation time — for example, “Product Banner Generator” becomes product-banner-generator — and the slug cannot be changed later. A descriptive name makes your API calls readable and your workflow easy to find.
1

Open the canvas

Go to knouds.ai and click New Workflow in the top bar or on the homepage.In the dialog that appears, choose From Scratch, then type a descriptive name for your workflow (for example, “Product Image Generator”). Click Create to open the blank canvas.
2

Add a Request Input node

The left sidebar lists all available node categories. Open the Inputs category and drag a Request Input node onto the canvas.In the node’s settings panel, click Add field and configure it:
  • Name: prompt
  • Type: Text
This field is what callers will provide when they run the workflow — either through the canvas form or via the API.

Add an Image Generator node and connect it

Open the Image Models category in the sidebar and drag an Image Generator node onto the canvas next to your Request Input node.Connect the nodes:
  1. Hover over the text output handle (orange dot) on the right edge of the Request Input node.
  2. Click and drag to the prompt input handle on the left edge of the Image Generator node.
  3. Release to create the wire.
With the Image Generator node selected, configure it in the panel on the right:
  • Model: choose your preferred image model from the dropdown.
  • Aspect ratio: set to your desired output dimensions (for example, 16:9).
Only nodes that are connected to the flow will execute. If you place a node on the canvas but leave it disconnected, it is skipped automatically when the workflow runs.
4

Add a Response Output node and connect it

Open the Outputs category in the sidebar and drag a Response Output node onto the canvas.Connect the image output handle (pink dot) on the right edge of the Image Generator node to the input handle of the Response Output node.The Response Output node is what the API returns and what the canvas displays after a run.
5

Run the workflow on the canvas

Click the Run button on the Image Generator node (the play icon in the node’s top-right corner). A prompt input form appears.Type a test prompt — for example: a golden retriever sitting in a sunlit park — and click Run.Knouds executes the connected nodes in order. You will see a progress indicator on each node as it runs.
6

View the result inline

Once execution completes, the generated image appears directly inside the Image Generator node and in the Response Output node. Click the image to expand it.If the result is not what you expected, adjust the prompt or model settings and click Run again — each run is independent.
7

Save the workflow

Click Save in the top bar (or press Cmd+S / Ctrl+S). Knouds writes the current node graph, settings, and last result to your account.Your workflow is now saved and callable via the REST API. See Deploy a workflow as a REST API for the next step.
