The Problem

An enterprise with over 2,000 employees struggled with fragmented internal documentation. Staff spent hours searching through PDF manuals, old wikis, and chat threads to answer policy and product questions, impacting overall operational efficiency.

The Solution

We engineered a secure, production-grade Retrieval-Augmented Generation (RAG) assistant. The pipeline parses, cleans, and indexes thousands of documents using an hybrid vector database. An LLM acts as the reasoning engine, providing grounded answers backed by specific source citations.

Engineering Challenges

Handling complex multi-column tables in financial PDFs, preventing hallucinations on legal clauses, and ensuring sub-second response times across high-volume user query streams.

Outcome & Performance

Reduced internal query lookup times by 78%, saving thousands of working hours monthly. Achieved 98% accuracy in fact extraction and positive feedback across human-in-the-loop review teams.
