LeCHECK
What LeCHECK is
LeCHECK is the contract-review feature of Lisse Legal AI Cowork, a service for legal work that also includes drafting, research, translation, matter management, and contract management. Upload a contract for AI findings on risky clauses, with suggested revisions and draft comments. The review can use a company’s criteria, templates, and past handling history, and compare the document with registered similar contracts or company templates to show differences. Review is available as a Microsoft Word add-in; the service is also described as SaaS accessed through a PC browser, with Windows and macOS support. Its research feature draws on sources such as e-Gov and government agencies, displays references with answers, and connects research results to review and drafting. More than 30 lawyers supervise the legal-focused AI, according to the maker, while a human staff member makes the final decision on review results. A free trial requires no credit card and does not automatically charge when it ends. Pricing depends on account count and organizational structure and is available by request.
