Lexi

Lexi is an intelligent operating system for legal work that provides a unified intelligence layer for lawyers, in-house legal teams, government agencies, and courts. It generates first drafts of letters, motions, contracts, and other documents in minutes in the firm's style, requiring minimal editing; tabular review aggregates answers from hundreds of documents and surfaces risky clauses early during contract review. Research searches precedents, statutes, and case law across jurisdictions in seconds, with complete verified citations; it also provides timeline building and one-click translation across 100+ languages for multilingual legal scenarios. The official page states that customer data is not used to train AI and that case files remain fully private, encrypted, and under the user's control, meeting the high security standards of the legal tech field.
