Building Bots

OmniBots uses a visual flow-based approach to bot building. Instead of writing code, you design conversation flows by dragging nodes onto a canvas, connecting them, and configuring each step. Behind the scenes, the platform handles LLM orchestration, context management, and channel delivery.

How It Works

Every bot in OmniBots is powered by one or more flows. A flow is a directed graph of nodes connected by edges. When a user sends a message, the orchestrator walks the graph -- evaluating conditions, calling LLMs, querying knowledge bases, and executing tools -- until it reaches a terminal node or hands off to a live agent.

Key Concepts

Concept	Description
Flow	A visual graph of nodes that defines a conversation path
Node	A single step in a flow (e.g., send a message, call an LLM, check a condition)
Edge	A connection between two nodes that defines the execution order
Variable	A named value stored in the session context, accessible by any node
Tool	An external API that the bot can call during a conversation
Knowledge Base	A collection of documents indexed for RAG-powered Q&A

Sections

Flow Builder

The visual canvas where you design conversation flows. Drag and drop nodes, connect them, and configure behavior.

Nodes Reference

Detailed reference for all 27 executable node types across 8 categories: Conversation, AI & Knowledge, Logic, Integration, NLU & AI Agents, Voice, Authentication, and more.

Knowledge Bases

Create document collections for retrieval-augmented generation (RAG). Upload files or connect external sources like SharePoint and Google Drive.

Tools

Register external APIs as tools that your bots can call during conversations to look up data, create records, or trigger actions.
