01
Fragmented knowledge
Precedents, contracts, memos, and case files were scattered across drives, DMS platforms, and email, making them hard to find.

50,000 documents, searchable in seconds, every answer traceable.
LexAI is a proprietary, secure RAG-powered chat system built for legal teams. It lets lawyers search, analyze, and draft from over 50,000 internal documents in seconds instead of hours, with every answer grounded in and traceable to source material. NEROCUBE designed and engineered LexAI end to end, from document ingestion to a production-ready legal assistant.
RAGDocument IntelligenceEnterprise AI
01 — Problem
The firm's knowledge existed, but nobody could reach it quickly
02
Time-intensive research
Associates spent up to 30% of billable time manually reviewing documents to answer routine questions or locate relevant clauses.
03
Confidentiality constraints
Public AI tools were off-limits due to client privilege, data residency, and compliance requirements.
04
Inconsistent output
Drafting and review quality varied without fast access to approved templates and prior work.
02 — Solution
A private assistant grounded only in the firm's own material
LexAI is a private, enterprise-grade AI assistant grounded exclusively in internal legal knowledge. It combines secure document pipelines, hybrid retrieval, and legal-aware reasoning.
01
Secure knowledge ingestion
Document pipeline
Automated ingestion, OCR, and chunking of PDFs, Word files, scans, and emails, with legal-aware parsing of clauses, sections, and citations.
Access-controlled indexing
Retrieval respects matter-level and user-level permissions, so users only see what they're authorized to see.
02
RAG chat and legal reasoning
Grounded Q&A
Conversational search across the full corpus, with answers backed by clickable citations to exact source passages.
Hybrid retrieval
Semantic and keyword search combined with reranking for high precision on legal terminology.
Drafting and review assistants
Clause comparison, contract summarization, and first-draft generation from approved precedents.
03
Governance and deployment
Private infrastructure
Deployed in a dedicated Azure tenant, so no data is used for model training.
Audit and oversight
Full query logs, source attribution, and human-in-the-loop review for high-stakes outputs.
