AI Legal Research for Law Firms

The Research Time Trap

Legal research is one of the most time-consuming activities in practice. A single research question can consume 3–8 hours of an associate's time, particularly when the issue spans multiple jurisdictions or involves an unsettled area of law. Multiply that across dozens of active matters and the hours add up quickly — often to the point where firms underinvest in research because of cost pressure, risking weaker arguments and missed precedents.

Lexi doesn't replace the judgment that attorneys bring to legal analysis. It eliminates the mechanical work of finding, reading, and organizing authorities so attorneys can focus on the strategic questions that actually require their expertise.

How Lexi Conducts Research in Slack & Teams

Research with Lexi is conversational and iterative. Ask a question the way you'd ask a senior associate, and Lexi responds with structured, sourced analysis:

1. Question interpretation. Lexi parses your research question to identify the legal issues, relevant jurisdiction, and applicable body of law. If the question is ambiguous, Lexi asks clarifying follow-ups before proceeding.
2. Multi-source search. Lexi queries across case law databases, statutory compilations, regulatory codes, and secondary sources simultaneously, using your firm's Westlaw or Fastcase subscription for authoritative primary sources.
3. Synthesis and analysis. Rather than returning a list of cases, Lexi synthesizes the results into a structured research memo that identifies the majority rule, minority positions, key distinguishing factors, and circuit splits or open questions.
4. Citation verification. Every case cited is checked for current validity. Overruled, vacated, or withdrawn authorities are flagged and excluded from the analysis. Lexi includes subsequent history for key citations.
5. Iterative refinement. Follow up with additional questions in the same thread — “How does the Ninth Circuit differ?” or “Find cases involving similar damages amounts” — and Lexi builds on its prior analysis.

Research Capabilities

Lexi handles the full spectrum of legal research tasks:

• Case law research across federal and state courts
• Statutory interpretation and legislative history
• Regulatory and administrative law research
• Standard-of-review analysis for motions and appeals
• Damages precedent research with comparable case details
• Procedural requirement verification for specific courts
• Contract clause benchmarking against market standards
• Cite-checking for briefs and motions before filing

Built for Accuracy, Not Hallucination

The risk of AI-generated legal citations that don't exist — so-called “hallucinations” — is well documented. Lexi addresses this head-on with a multi-layer verification approach:

• Source-grounded responses. Lexi's research outputs are grounded in actual retrieved documents, not generated from parametric memory. Every claim is linked to a specific source.
• Citation links. Each citation includes a direct link to the full text on Westlaw or Fastcase, making verification immediate.
• Confidence scoring. Lexi assigns a confidence level to each research conclusion, distinguishing between well-settled law, emerging trends, and areas of genuine uncertainty.
• Transparent limitations. When Lexi cannot find authority directly on point, it says so — and suggests the closest analogous authorities or alternative research approaches.

From Research to Action

Research rarely exists in isolation. Once you've found the authorities you need, Lexi can transition directly into document drafting, incorporating the research findings into a motion or brief. Pair it with deadline tracking to ensure the resulting filing meets all applicable deadlines. The entire workflow — research, draft, review, file — can happen in a single Slack or Teams thread.

Integrations

Lexi's research engine integrates with Westlaw and Fastcase for primary source access, Clio Manage for matter context, and your firm's internal knowledge base for work product reuse. Research memos can be exported as Word documents or saved directly to NetDocuments or SharePoint. All research activity is logged for accurate time tracking and billing.
