The challenge

The client wanted an assistant able to answer over internal documentation, without data leakage or uncontrolled hallucination, with source traceability required for compliance.

The solution

We built a RAG pipeline with LangChain and pgvector: secure document indexing, contextual retrieval, output guardrails and systematic source citation. A business evaluation set measures quality continuously.

The results

A reliable assistant whose every answer is traceable to its sources, continuously evaluated, and compliant with data security requirements.
