Platform Components

​
Workflow Engine

The core of Nadoo AI — a LangGraph-based visual workflow engine where you connect nodes to build AI agent logic. Each workflow is a directed graph that processes user inputs through chains of AI reasoning, knowledge retrieval, conditional branching, and external tool calls.
Perfect for: Teams building complex AI agents that require multi-step reasoning, tool use, and conditional logic

​
Knowledge Base

Ingest documents (PDF, DOCX, TXT, Markdown) into a vector store powered by PostgreSQL with pgvector. The RAG pipeline supports hybrid search combining dense vector similarity with BM25 keyword matching, plus optional reranking for improved relevance.
Perfect for: Organizations that need AI agents grounded in their own documents and data

​
Multi-Channel Messaging

Connect your AI agents to the messaging platforms your users already use. Each channel integration handles authentication, message formatting, and bidirectional communication.
  • Slack — Bot integration with slash commands and thread support
  • Discord — Bot with channel and DM support
  • Telegram — Bot API integration
  • KakaoTalk — Channel and chatbot integration
  • Microsoft Teams — Bot Framework integration
  • WhatsApp — Business API integration

​
Knowledge Graphs

Build structured knowledge representations using RDF/OWL ontologies. Query with SPARQL and enable multi-hop reasoning across connected entities for complex question answering.

​
Plugin SDK and Skills

Extend the platform with custom Python plugins that access LLMs, knowledge bases, tools, and storage. The Skills system lets you import reusable executable units from Git repositories.

Use Cases

Customer Support Automation

Build AI agents that answer questions from your knowledge base, handle multi-turn conversations, and escalate to humans when needed — deployed across Slack, Teams, or your website.

Internal Knowledge Assistant

Ingest company documents into the Knowledge Base and let employees query policies, procedures, and technical documentation through natural language chat.

Multi-Channel Chatbot

Design a single AI workflow and deploy it simultaneously to Slack, Discord, Telegram, KakaoTalk, and WhatsApp with channel-specific formatting.

Document Processing Pipeline

Build workflows that ingest documents, extract structured data with AI, validate results, and route to downstream systems.

AI-Powered Data Analysis

Create agents that query databases, analyze data, generate visualizations, and produce reports using Code Executor and AI Agent nodes.

Workflow Automation

Chain together HTTP Request, Condition, and AI Agent nodes to automate complex business processes with intelligent decision-making.
