Overview
Marlocks Technologies developed Kore-Legal AI, an advanced internal legal assistant for Perchstone and Graeys. By leveraging Amazon Bedrock and the firm’s proprietary knowledge base, the solution automates legal research and document drafting, achieving a 30–50% reduction in research time.
Perchstone and Graeys is a premier, full-service Nigerian law firm. Their practice areas include customary law, trust and estate planning, corporate law, and electoral litigation. Since 1974, the firm has accumulated a vast repository of legal precedents, court processes, and internal legal opinions across multiple levels of the Nigerian court system.
The Challenge
The firm faced several operational challenges that hindered efficiency and knowledge utilization:
Inefficient Research
Significant time was lost manually searching through decades of historical precedents and legal opinions.
Redundancy
Legal work was frequently duplicated across different offices and practice groups due to a lack of centralized knowledge retrieval.
Drafting Bottlenecks
Creating first drafts for pleadings and memos was a slow, manual process.
Underutilized Assets
The firm had a limited ability to leverage its extensive historical knowledge base for contemporary cases effectively.
The Solution
Marlocks Technologies implemented Kore-Legal AI, a comprehensive AI-powered assistant built on enterprise-grade AWS infrastructure. Key technical components included:
Intelligent Retrieval
Used Amazon Bedrock and Titan Embeddings v2 to enable context-aware semantic search across the firm’s private knowledge base.
Advanced Data Processing
Deployed an ingestion pipeline using Amazon Textract to perform OCR on historical documents and handwritten notes, converting them into searchable digital assets.
Automated Drafting
Configured the system to generate structured first-draft legal memos, pleadings, and contemporary articles based on retrieved precedents.
Security & Compliance
Established secure access controls to ensure the AI only generated responses using approved internal data, maintaining strict legal confidentiality.
Results & Benefits
The Proof of Value (PoV) demonstrated significant measurable improvements in firm operations:
Enhanced Productivity: Achieved a 30–50% reduction in manual research time during workflow testing.
High Accuracy: The AI retrieved relevant documents with ≥95% relevance accuracy and maintained 95–98% factual consistency in legal research answers.
Rapid Turnaround: Generated usable first drafts of legal documents within 10–20 seconds, drastically accelerating the drafting phase.
Strategic Advantage: Anticipated a 20–30% enhancement in the firm’s competitive advantage within the Nigerian legal market.
User Satisfaction: Reached an 85%+ satisfaction rating from participating lawyers.
Lessons Learned
OCR is Critical for Legacy Data: Integrating Amazon Textract was essential for unlocking decades of historical, often handwritten, legal data that was previously unusable for digital search.
Strict Grounding Prevents Hallucination: Implementing secure access controls to restrict the AI’s knowledge base strictly to approved internal data was vital for maintaining the 95–98% factual consistency required in the legal field.
Efficiency Drives Adoption: Achieving a 10–20 second turnaround for first drafts was a primary factor in reaching an 85%+ user satisfaction rating, as it directly addressed the firm’s most significant bottleneck.
