AI Legal Research & Summarization
AI Legal Research & Summarization ingests case law, contracts, and filings to automatically extract key facts, holdings, precedents, and issues, then generates concise, citation-rich summaries. It accelerates legal research, enhances drafting quality, and reduces time spent reviewing lengthy documents, enabling law firms and legal departments to handle more matters with greater consistency and lower cost.
The Problem
“Cut legal research and review time with citation-grounded summaries”
Organizations face these key challenges:
Associates spend hours skimming cases/contracts to find relevant issues, holdings, and clauses
Inconsistent memo quality and missed citations due to manual copy/paste and ad-hoc research trails
Difficulty reusing institutional knowledge across matters and practice groups
High cost and slow turnaround when reviewing large volumes of filings, exhibits, or discovery documents

Closed-Loop Research-to-Draft Legal Copilot with Tool-Using Agents and Continuous Learning
Quick Win
API Wrapper
Stand up a minimal workflow that ingests PDFs (opinions, filings, contracts) using managed OCR/document intelligence when needed, then prompts a frontier chat LLM to produce a structured summary (facts/issues/holding/analysis) and a simple list of quoted passages with page/paragraph references. Use a lightweight UI (web form or Teams/Slack bot) and store outputs in the DMS as an attachment to the source document.
Key Challenges
- ⚠Limited retrieval depth (works best per-document, not across a corpus)
- ⚠Citation quality depends on OCR/text extraction and prompt discipline
- ⚠Minimal integration with existing research tools and matter metadata
- ⚠Higher risk of missed nuances without practice-area-specific tuning
