Overview

​

Types of Nodes

1. Start Node:
   • Automatically created and unique for every flow.
   • Marks the entry point of the conversation or interaction.
   • Note: You can only have one start node per flow.
2. Default Nodes:
   • Represent operations or decision points within the flow.
   • Used to route data and manage the conversation logic.
3. End Nodes:
   • Conclude the conversation, call, or chat.
   • Helps in marking logical endpoints for a flow.
4. Global Nodes:
   • Accessible throughout the entire flow.
   • Created by toggling the Global Node switch on a default node.
   • Useful for defining reusable functionality, such as shared prompts or tools.

​

Customizing Nodes

Clicking on any node (start, default, global) opens a menu with the following customization options:

​

1. Overview

• Define the node’s name and description for clarity.
• Assign specific instructions for AI behavior when routing through this node.

​

2. LLM Configuration

• Set parameters like temperature, token limits, and other model-specific options.
• Tailor how the AI responds within this specific node.

​

3. Tools Integration

• Connect tools (e.g., APIs or webhooks) to the node.
• Define the tools the AI can call when processing this part of the flow.

​

4. Knowledge Base

• Enable the AI to retrieve relevant information from a vector database.
• Specify the number of retrieval chunks and adjust the settings for knowledge-based responses.

​

5. Router Configuration

• Manage conditional logic for branching flows.
• Add conditions to define how the data moves between nodes.

2. Default Node Example:
   • Process the user’s input and provide a response.
     The Default Node configuration menu showing the processing prompt setup.
3. End Node Example:
   • Conclude the conversation with a friendly closing message.
     The End Node configuration menu showing the closing prompt setup.
4. Global Node Example:
   • Define a shared prompt for handling “Help” requests.

Scheduling Assistant Example

• The Start Node greets the user and identifies their intent.
• A Default Node processes the scheduling details using integrated tools.
• A Global Node defines shared responses like “Help” or “Cancel.”
• The End Node finalizes the booking or provides a summary.
