Spec score 8.3 #6 of 20 in AI Contract Review Software

What it is

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.
