Core Concepts
Understanding Nodes
A node is a single step in your workflow.
It takes an input, transforms it, and produces an output. That output becomes the input for the next node.
Think in transformations
Don't think in tools. Think in transformations.
- What do I start with?
- What do I want to get?
- What step gets me closer?
Each step = one node.
Types of nodes
Nodes are grouped by what they do:
- Input nodes — bring content in (text, image, video, audio)
- AI nodes — generate or transform content using AI
- Processing nodes — combine, trim, or modify outputs
- Parameter nodes — control style, tone, or duration
- Asset nodes — reuse characters, faces, objects, locations
- Output nodes — save or export the final result
You don't need to memorize them. Just pick the node that matches the step you need.
How nodes connect
Every node has connection points on its sides.
Connect the output of one node to the input of another.
When you click Run, the data flows through the chain.
AI Agent nodes
AI Agent nodes are where ideas begin.
They use:
- System Prompt → defines how the agent thinks
- User Input → defines what you want
The golden rule
A node should do one thing well.
If you need to generate text and create an image, use two nodes — not one.
That's what makes workflows flexible.
