Project Overview
Legal professionals deal with vast volumes of complex documents including contracts, court judgments, regulatory guidelines, legal opinions, and compliance records. Traditional document review methods rely heavily on manual reading and keyword-based searches, which are time-consuming and prone to oversight.
To address this challenge, we developed a Document Question Answering System powered by Generative AI for a Legal Tech client. The solution enables lawyers and legal researchers to ask natural language questions and receive precise, context-aware answers derived directly from their legal document repositories.
This system transforms static legal documents into an interactive, conversational knowledge layer that significantly improves research efficiency and decision-making.
Business Challenges
The client faced multiple operational and research challenges:
- Large volumes of unstructured and semi-structured legal documents
- Time-intensive manual legal research and document review
- Difficulty extracting specific clauses or interpretations quickly
- Inconsistent understanding of legal language across teams
- Limited visibility into relevant information buried in long documents
- Increasing workload without proportional team scaling
These challenges slowed case preparation, increased operational costs, and reduced overall productivity.
What We Delivered
We delivered a Generative AI-driven legal document intelligence platform designed specifically for legal workflows:
Key deliverables include:
- Natural language question-answering across legal documents
- Context-aware responses generated using large language models
- Intelligent summarization of lengthy legal texts
- Clause-level understanding for contracts and policies
- Conversational interface tailored for lawyers and legal analysts
- Secure document ingestion and access control
The system allows legal teams to interact with documents as if consulting a knowledgeable legal assistant.
Proposed Architecture & Design
The solution architecture was designed to balance performance, accuracy, and scalability:
High-level interaction flow:
- Legal documents ingested from PDFs, Word files, and internal repositories
- Text normalization and preprocessing for legal terminology
- Generative AI models optimized through prompt engineering for legal use cases
- Context window management to handle long-form legal content
- API-driven architecture connecting frontend interfaces with AI services
- Secure authentication and role-based access for legal users
This modular design ensures reliable performance and easy extensibility.
