# Node Overview
OpenCompany uses a visual node-based system for building workflows. Each node performs a specific function and passes data to connected nodes.
## Node Categories
The node palette groups plugins by category. The exact node count grows as new plugins ship, so use the palette in the app for the live list.
| Category | Description |
| - | - |
| [AI Chat Models](/nodes/ai-models) | OpenAI, Anthropic, Gemini, OpenRouter, xAI, Groq, Cerebras, DeepSeek, Kimi, Mistral, Ollama, LM Studio |

## Node Shapes
Different shapes indicate different node types:
| Shape | Type | Description |
| - | - | - |
| Diamond | Trigger | Starts a workflow (no input handle) |
| Square | Action | Performs operations |
| Circle | Config | Provides configuration to other nodes |
## Handles
Handles are connection points on nodes:
### Input Handles (Left Side)
* **Main Input** - Receives data from upstream nodes
* **Config Inputs** - Diamond shapes for memory, model, etc.
### Output Handles (Right Side)
* **Main Output** - Sends data to downstream nodes
## Data Flow
Data flows from left to right through connections:
```
[Trigger] --> [Process] --> [Action] --> [Response]
```
### Template Variables
Access upstream data using template syntax:
```
{{nodeName.fieldName}}
```
**Examples:**
```
{{webhookTrigger.body}} // Webhook request body
{{aiAgent.response}} // AI Agent's answer
{{batteryMonitor.level}} // Battery percentage
{{whatsappReceive.text}} // Message content
```
### Nested Fields
Access nested objects with dot notation:
```
{{whatsappReceive.group_info.sender_name}}
{{webhookTrigger.body.user.email}}
```
## Node Configuration
Click a node to open its parameter panel — the full editing how-to (adding, connecting, renaming, copying, deleting, shortcuts, palette modes) lives on [The canvas](/canvas).
### Parameter Types
| Type | Description |
| - | - |
| Text | String input |
| Number | Numeric input |
| Boolean | Toggle on/off |
| Options | Dropdown selection |
| Slider | Range selection |
| Code | Multi-line code editor |
| JSON | JSON object input |
### Dynamic Options
Some parameters load options from the backend:
* Device lists (Android)
* AI models (based on API key)
* Groups and contacts (WhatsApp)
## Node States
During execution, nodes show their state:
| State | Indicator | Description |
| - | - | - |
| Idle | Default | Not running |
| Waiting | Cyan | Trigger waiting for event |
| Running | Purple glow | Currently executing |
| Completed | Green | Finished successfully |
| Error | Red | Failed with error |
## Special Node Types
### Trigger Nodes
* No input handle
* Start workflow execution
* Wait for external events
**Examples:** Webhook Trigger, WhatsApp Receive, Cron Scheduler
### Config Nodes
* Connect to special config handles (diamonds)
* Provide settings to parent nodes
* Don't execute independently
**Examples:** Simple Memory, AI Models
## Best Practices
Name your nodes descriptively. "Process Order" is better than "AI Agent 1".
Test individual nodes with the **Run** button before deploying full workflows.
Config nodes (Memory, Models) connect to diamond handles, not main inputs.
