LeCHECK
LeCHECK is the contract review feature of Lisse Legal AI Cowork, which also covers legal drafting, research, translation, matter management, and contract management. Users can submit a contract for risk findings, suggested revisions, and comment drafts. Review can draw on an organization’s criteria, templates, and past handling history, and compare a contract with registered similar contracts or company templates to show differences. LeCHECK works as a Microsoft Word add-in; the maker says no special system migration is needed. Its research feature draws on sources such as e-Gov and government agencies, shows references with answers, and connects results to review and drafting. The maker says more than 30 lawyers supervise the legal-focused AI, but a human staff member makes the final legal decision. The service is accessed as SaaS from a PC browser, with Windows and macOS support and current Chrome or Edge recommended. Pricing depends on account count and organization structure and is available by request. A free trial requires no credit card and does not automatically charge when it ends.
