NodeZen is a visual workflow builder inside Artnex. You connect AI tools together as nodes on a canvas, define how data flows between them, and run the entire pipeline with a single click. Use it to automate repetitive AI tasks, build multi-step image generation pipelines, or create reusable workflows you can run again and again.Documentation Index

Navigate to NodeZen
Go to Tools → NodeZen in the left sidebar. The NodeZen editor opens with a blank canvas and a node palette on the left.The editor layout
Node canvas
The central area where you drag, drop, and connect nodes. Supports pan and zoom.
Node palette
The left panel listing all available node types, grouped by category. Drag any node onto the canvas to add it.
Properties panel
Opens on the right when you click a node. Configure the node’s settings such as model, aspect ratio, or number of outputs.
Top toolbar
Contains Play to run the workflow, Save to save it, Export to export it, and undo/redo controls.
Available node types
Nodes are grouped into six categories.- Input
- Generation
- Editing
- Utility
- Export
Input nodes supply data to your workflow. They have no incoming connections.
| Node | Description |
|---|---|
| Text Prompt | Enter a text prompt to feed into generation nodes |
| Image Upload | Upload an image from your computer |
| Style Reference | Upload a reference image to guide style in generation |
Connecting nodes
Every node has input handles (left side) and output handles (right side), shown as small dots on the node edges. To connect two nodes:- Hover over an output handle on the source node until the cursor changes.
- Click and drag from the output handle to the input handle of the destination node.
- Release to create the connection. A animated line (edge) appears between the nodes.
Delete.
Running a workflow
Click the Play button in the top toolbar to execute the workflow. NodeZen processes nodes in order, passing outputs downstream through the edges you have drawn. Each node shows a status indicator:- Idle — waiting to run
- Running — currently processing
- Success — completed, output available
- Error — failed, hover for the error message
Running a workflow deducts credits for every generation and editing node it contains. The total credit cost is calculated from all nodes before execution begins. You will see a confirmation if you do not have enough credits.
Saving and naming a workflow
Click Save in the top toolbar. A dialog asks for a workflow name and optional description. Enter a name and click Save. Saved workflows appear in the My Workflows tab on the left panel. Click any saved workflow to load it back onto the canvas.Workflow templates
NodeZen includes a library of built-in workflow templates so you can start from a working example instead of building from scratch. Open the Templates tab in the left panel to browse available templates. Templates are grouped into categories: image, video, audio, and mixed. Featured templates appear at the top. Click Use Template on any template card to load it onto the canvas. You can then run it immediately or modify it to suit your needs.Exporting a workflow
Click Export in the top toolbar to open the Export Workflow dialog. This saves your workflow configuration (nodes, edges, and settings) so you can import it later or share it with others.Use cases
Automated image generation pipeline
Automated image generation pipeline
Connect a Text Prompt node → ImageZen Generator → Background Remover → Export Image. Enter your prompt once and the workflow generates an image, removes its background, and downloads the result automatically.
Batch image variations
Batch image variations
Connect a Text Prompt node → Batch Generator → ImageZen Generator → Save to Gallery. The Batch Generator runs the image generator multiple times, producing several variations from the same prompt in one click.
Image-to-video pipeline
Image-to-video pipeline
Connect an Image Upload node → VideoZen Generator → Export Video. Upload a photo and the workflow animates it into a video and downloads the result.
Text-to-speech with style-guided image
Text-to-speech with style-guided image
Connect a Text Prompt node to both a VoiceZen TTS node and an ImageZen Generator node. Use a Style Reference node to guide the image style. Run the workflow to produce a matching audio clip and image together.
Build your first workflow
Add a Text Prompt node
Find Text Prompt in the node palette under the Input category. Drag it onto the canvas.
Configure the prompt
Click the Text Prompt node to select it. In the Properties panel on the right, type your image description — for example,
A neon-lit cityscape at night, photorealistic.Add an ImageZen Generator node
Drag the ImageZen Generator node from the palette onto the canvas, to the right of the Text Prompt node.
Connect the nodes
Drag from the Text output handle of the Text Prompt node to the Prompt input handle of the ImageZen Generator node. An animated edge connects them.
Add an Export Image node
Drag the Export Image node onto the canvas to the right of the ImageZen Generator. Connect the Image output of the generator to the Image input of the export node.
Run the workflow
Click Play in the top toolbar. NodeZen runs the workflow. When the ImageZen Generator node turns green, your image is ready and the export node downloads it automatically.
