What Are Workflows?

Learn what Workflows are in PropellerDeck — visual, node-based AI automation pipelines that connect multiple AI agents and processing steps.

What Are Workflows?

Workflows in PropellerDeck are visual, node-based AI automation pipelines. Instead of a single AI agent handling everything in one conversation, a Workflow breaks complex tasks into a series of connected steps — each step handled by a specialized node.

How Workflows Are Structured

Every Workflow follows a simple pattern: input → processing → output. Data enters the workflow, passes through one or more processing nodes, and produces a final result. You can see this flow visually on the canvas, where nodes appear as blocks and connections appear as lines between them.

What Is a Node?

Each node in a Workflow is a single step that performs a specific role:

  • AI Agent nodes use reasoning and language understanding to handle open-ended tasks
  • Function nodes run deterministic code for data transformation or API calls
  • Decision nodes branch the flow based on conditions in your data
  • Human nodes pause execution to wait for a person to review or approve
  • System nodes mark the entry and exit points of the workflow

For a full breakdown of every node type, see Node Types.

Why Use Workflows Instead of a Single Agent?

Workflows let you divide complex problems into specialized roles. A customer service pipeline might classify an inquiry, route it to the right department, and generate a tailored response — each handled by a different node. This produces more reliable, auditable results than asking one agent to do everything at once.
