Lumen Vault

RAG knowledge system that cites its sources correctly

Indexes 40K+ internal documents

Sub-second retrieval

Source citation on every answer

Overview

Lumen Vault is a retrieval-augmented copilot built on top of Lumen Labs' internal documentation and product data. Every answer links back to the exact source passage, so the team can verify instead of guess.

What we built

  • Retrieval-augmented generation over internal docs
  • Vector database with incremental re-indexing
  • Source-linked, verifiable answers
  • Role-based access to sensitive documents
  • Slack & API integration
