Jarvis:
A Knowledge Graph-Enhanced RAG Platform for Explainable AI Decisions
A production-grade AI platform delivering explainable, domain-specific decision support using a Knowledge Graph-enhanced Retrieval-Augmented Generation (RAG) architecture.
The Project Overview

Accurate & Explainable AI
Traditional RAG systems retrieve documents and rely solely on retrieved context, but domain-specific decision support requires responses that are both accurate and explainable. Jarvis needed an AI platform capable of intelligently routing different query types to specialized retrieval strategies while safely ingesting live web content into conversation-aware context without compromising grounding or introducing safety risks.
Enterprise-Grade Observability & Safety
The platform also required enterprise-grade observability and safety validation because it supports economically and clinically sensitive workflows where inaccurate or overconfident AI responses could have serious consequences.
Multi-Agent Orchestration
Toadsters architected a multi-agent workflow using LangGraph to orchestrate intelligent query routing, hybrid retrieval, response generation, and safety validation as coordinated services rather than a single AI generation step. A FastAPI backend with Server-Sent Events enabled real-time streaming conversations, stateful chat sessions, and asynchronous document ingestion.
Hybrid Retrieval & Knowledge Graph
Hybrid retrieval combined Milvus vector search with graph-aware context assembly to improve both retrieval accuracy and explainability. A custom Clipper ingestion pipeline transformed browser-clipped HTML into conversation-aware knowledge, while Langfuse observability, confidence scoring, safety validation, background processing, and Docker-based deployments ensured enterprise-grade reliability, traceability, and maintainability.
Enterprise Architecture
Built with modern, scalable technologies designed for high-throughput data pipelines and robust orchestration.
Measurable Success
Explainable AI Decisions: Knowledge Graph-enhanced retrieval provides grounded, traceable responses that explain why each answer was generated.
Intelligent Multi-Agent Orchestration: LangGraph routes every query through specialized retrieval, reasoning, and safety workflows to maximize response quality.
Enterprise-Grade Reliability: Safety validation, observability, and real-time streaming architecture ensure secure, scalable AI decision support for mission-critical applications.
"What sets Jarvis apart from a standard chatbot is that every answer can be traced back to why it was generated. That explainability was non-negotiable for us, and Toadsters built it into the architecture, not bolted on after."
