Nova: Enterprise Multimodal Document AI & RAG
Private retrieval-augmented generation engine transforming 50,000+ complex contracts into verified insights.
Engineered an enterprise-grade private RAG pipeline that ingests heterogeneous legal contracts, parses complex tabular data, and enables real-time citation-backed conversational queries with zero data leaks.
The Challenge
The client's compliance attorneys spent over 18 hours weekly manually cross-referencing multi-jurisdiction supplier agreements. Standard off-the-shelf chatbots frequently hallucinated clause numbers and could not interpret nested tables or scanned addendums.
Core Objectives
Approach & Architecture
We developed a specialized OCR and semantic chunking pipeline that preserves document layout and hierarchy. Ingested vectors are stored in a self-hosted Qdrant cluster with metadata filtering. Queries run through a re-ranking model before reaching the LLM.
Hierarchical semantic chunking preserving section headers and table structure
Two-stage retrieval: dense embeddings + BM25 keyword matching re-ranked by Cohere model
Streaming SSE (Server-Sent Events) Next.js frontend with real-time PDF page jump-links
Defensive Security & Compliance Measures
Every engagement incorporates zero-trust engineering standards to ensure data sovereignty, cryptographic integrity, and compliance readiness.
Verified Outcomes
Contract analysis time dropped from 3.5 hours per file to under 25 minutes
Enforced strict citation refusal when supporting clauses were absent
Scalable asynchronous Celery workers handling bulk batch uploads
