LegalForce (リーガルフォース) is a Japanese AI-powered contract review service that combines advanced technology with lawyer-verified legal expertise. It supports legal teams from the initial screening of contract risks to research, revision, and case management, replacing many of the manual, time-intensive tasks traditionally associated with contract review. The service is designed for companies of various sizes, from one-person legal departments to large in-house teams, as well as law firms that need to deliver faster, more reliable client support.
Luminance is a legal AI platform, founded by mathematicians in 2015, that automates contract drafting, negotiation, and analysis across the full contract lifecycle.
