# Node Reference

> Explore the Node reference documentation for configuring Flows in Cognigy.AI, including Basic, Logic, Voice, Analytics, Service, AI, and other Node categories.

This Node reference provides details about the [Nodes'](/ai/agents/develop/nodes/overview) parameters to help you configure your [Flow](/ai/agents/develop/projects-and-flows/overview).

## Node Categories

<CardGroup cols={3}>
  <Card title="Basic" href="/ai/agents/develop/node-reference/basic/overview">
    Use Basic Nodes for basic conversational Flows, for example, the [Say Node](/ai/agents/develop/node-reference/basic/say) and the [Question Node](/ai/agents/develop/node-reference/basic/question).
  </Card>

  <Card title="Logic" href="/ai/agents/develop/node-reference/logic/overview">
    Use Logic Nodes to control the Flow execution, for example, the [If Node](/ai/agents/develop/node-reference/logic/if) and the [Lookup Node](/ai/agents/develop/node-reference/logic/lookup).
  </Card>

  <Card title="Voice" href="/ai/agents/develop/node-reference/voice/overview">
    Voice Nodes are for developing voice AI Agents.
  </Card>

  <Card title="Analytics" href="/ai/agents/develop/node-reference/analytics/overview">
    Nodes for tracking and analyzing conversation data and taking advantage of Cognigy AI's comprehensive marketing functionality.
  </Card>

  <Card title="CXone" href="/ai/agents/develop/node-reference/cxone/overview">
    Nodes for integrating NiCE CXone into your Flows.
  </Card>

  <Card title="Service" href="/ai/agents/develop/node-reference/service/overview">
    Use Service Nodes to trigger external services, like databases and email servers. Additional services can be added through [Extensions](/ai/for-developers/extensions).
  </Card>

  <Card title="AI" href="/ai/agents/develop/node-reference/ai/overview">
    AI Nodes are a collection of Nodes for Cognigy.AI [NLU](/ai/platform-features/nlu/overview) and [Agentic AI](/ai/agents/overview).
  </Card>

  <Card title="Data" href="/ai/agents/develop/node-reference/data/overview">
    Data Nodes are designed to manage, manipulate, process, or store data.
  </Card>

  <Card title="Agent Copilot" href="/ai/agents/develop/node-reference/agent-copilot/overview">
    Nodes for creating the Agent Copilot workspace.
  </Card>

  <Card title="xApps" href="/ai/agents/develop/node-reference/xApp/overview">
    Nodes for creating xApps.
  </Card>

  <Card title="Other" href="/ai/agents/develop/node-reference/other-nodes/overview">
    Additional specialized Nodes.
  </Card>
</CardGroup>

If you want to create a custom Node, go to the [Extensions](/ai/for-developers/extensions) section.

<Note>
  Nodes can belong to multiple categories for easier search and navigation. In the following sections, each Node is assigned to a single category to avoid duplicated descriptions.
</Note>

## Common Sections to All Node Types

### Settings

All Node types include the **Settings** section, which contains the following parameters:

| Parameter      | Description                                                                                                              |
| -------------- | ------------------------------------------------------------------------------------------------------------------------ |
| Label          | The name of the Node that is displayed in the Flow editor. This is useful to distinguish between Nodes of the same type. |
| Comment        | A comment that is displayed in the Flow editor. This is useful to add additional information about the Node.             |
| Analytics Step | An [analytic step](/ai/agents/analyze/analytics-steps) to track which paths users take in the Flow.                      |

### Mocking

Use this section to control [Mocking](/ai/agents/test/mocking) at the Node level.
