Overview
Discovery AI Assistant is an intelligent eDiscovery platform that transforms how legal teams handle document review, case preparation, and legal research. By combining advanced natural language processing with domain-specific legal knowledge, the platform acts as a tireless paralegal assistant, capable of reviewing thousands of documents, identifying key evidence, and providing contextual insights in minutes rather than weeks.
The Challenge
Modern legal discovery involves reviewing massive volumes of digital documents—emails, contracts, financial records, and communications—often numbering in the hundreds of thousands. Traditional manual review is:
- Prohibitively Expensive: Paralegals and junior associates spend thousands of billable hours on document review
- Error-Prone: Human fatigue leads to missed critical evidence and inconsistent categorization
- Time-Consuming: Cases drag on for months while teams sift through document repositories
- Inconsistent: Different reviewers apply varying standards and interpretations
Law firms needed an AI solution that could augment their teams with paralegal-level intelligence while maintaining the accuracy and nuance required in legal work.
Research & Discovery
User Research
We conducted extensive interviews with:
- Litigation Attorneys (15 participants): Understanding case strategy and evidence needs
- eDiscovery Specialists (12 participants): Learning existing workflows and pain points
- Paralegals (20 participants): Identifying repetitive tasks and decision-making patterns
- Legal IT Directors (8 participants): Understanding technical constraints and compliance requirements
Key Insights
- Context is Everything: Legal professionals need to understand not just what a document says, but its relevance to specific legal issues, timelines, and relationships between parties
- Trust Through Transparency: Lawyers won't trust AI recommendations without understanding the reasoning and being able to verify sources
- Flexible Categorization: Every case has unique issues and categories—rigid taxonomy doesn't work
- Privilege Protection: Maintaining attorney-client privilege and work product protection is non-negotiable
The Solution
AI-Powered Document Intelligence
Smart Document Ingestion

Natural Language Understanding The core AI engine uses advanced NLP to:
- Understand legal concepts and terminology (leveraging Legora legal language models)
- Identify key entities: people, organizations, dates, monetary amounts, legal terms
- Extract contractual obligations, deadlines, and commitments
- Recognize sentiment and communication tone
Intelligent Categorization
- Custom issue tagging based on case-specific legal issues
