How It Works

From Idea to Production in 4 Steps

Design your AI agent's conversation logic visually, test it thoroughly, and deploy with confidence.

1

Design Your Flow

Use the visual flow builder to drag and connect nodes. Define the conversation logic, branching conditions, and integrations your AI agent needs.

2

Configure Nodes

Each node has its own configuration — set prompts for LLM nodes, API endpoints for integrations, conditions for branches, and templates for outputs.

3

Test in Playground

Run your flow in the built-in playground with simulated calls. Test edge cases, monitor latency, and validate responses before going live.

4

Deploy & Monitor

Publish your flow to production with zero downtime. Monitor real-time metrics, sentiment analysis, and conversation quality through the analytics dashboard.

Node Types

Powerful Building Blocks

Each node type serves a specific purpose. Combine them to create sophisticated voice agents that can handle any customer interaction scenario. Click any node to see technical details.

Chat Input

Input/Output

Receives the customer's voice or text input and converts it into structured data for processing.

Chat Output

Input/Output

Delivers the AI agent's response back to the customer in natural, human-like voice.

LLM Processing

Intelligence

The brain of the flow — processes context, generates responses, and makes decisions based on conversation history.

Condition Branch

Logic

Routes the conversation to different paths based on customer intent, sentiment, or extracted data.

API / MCP Call

Integration

Connects to external systems — CRM, databases, payment gateways — to fetch or update information in real-time.

Email / SMS

Integration

Sends automated follow-up emails, SMS confirmations, or notifications during or after the call.

Array / Loop

Logic

Iterates over lists of items — like insurance plans, product options, or appointment slots — to present them to the customer.

Knowledge Base

Intelligence

Retrieves relevant information from your company's documents, FAQs, and policies to provide accurate answers.

Call Transfer

Telephony

Seamlessly transfers the call to a human agent when the AI determines escalation is needed.

Validation

Logic

Validates customer-provided data like phone numbers, emails, policy numbers, or dates before proceeding.

Architecture

Built for Scale & Reliability

Under the hood, the Flow Engine is designed for enterprise-grade performance with event-driven execution, stateful context management, and zero-downtime deployments.

Event-Driven Execution

Each node emits events that trigger the next step. This enables parallel execution, retry logic, and real-time monitoring without blocking the conversation flow.

Stateful Context

The flow maintains a shared context object throughout the conversation. Every node can read from and write to this context, enabling complex multi-turn interactions.

Version Control

Every flow change is versioned. Roll back to any previous version instantly, compare diffs, and maintain separate staging/production environments.

Hot Reload

Update flows in production without dropping active calls. New calls use the latest version while existing calls complete on their current version.
