Preview
Display any result type (text, image, video, audio) in the workflow editor for inspection.
Overview
The Preview node renders the output of any upstream node directly in the workflow editor canvas. It accepts all media types – text, images, video, and audio – and displays them inline. Multiple upstream connections are supported, with results displayed as an ordered list that persists its ordering across re-executions.
Configuration
| Field | Type | Default | Description |
|---|---|---|---|
| Preview Items | PreviewItem[] | [] |
Auto-populated list of received results from upstream nodes. |
| Item Order | string[] | [] |
Persisted ordering of preview items by source node ID. Survives re-execution so items remain in the same visual order. |
Inputs & Outputs
Inputs:
in– Accepts any media type. Multiple upstream connections supported.
Outputs: None. This is a display-only node.
Best Practices
- Place Preview nodes at key points in your workflow to monitor intermediate results.
- Use multiple Preview nodes to compare outputs from different branches of a workflow.
- Remove Preview nodes before deploying automated workflows (they serve no purpose without a user viewing the editor).
Common Use Cases
- Debugging workflow logic by inspecting intermediate outputs.
- Comparing results from different AI models or parameter settings side by side.
- Previewing generated images, audio, or video before sending to output nodes.
- Monitoring text outputs (scripts, captions, prompts) at various stages of processing.
Tips
- The item order is persisted, so reordering is preserved when you re-run the workflow.
- Preview supports all media types: text renders as formatted text, images render inline, video shows a player, and audio shows a playback control.
- This node has no outputs – it is purely for visual inspection in the editor.
- Preview nodes are lightweight and do not affect workflow performance.
