LeCHECK review
A lawyer-supervised review service for Japanese-English contracts and structured legal workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
LeCHECK is a cloud-based AI contract review service from Lisse Co., Ltd. It is designed for corporate legal teams, business users, and law firms that need a more consistent way to review contracts. The service analyzes uploaded PDF and Word documents, highlights legal risks and missing clauses, explains review points, and suggests alternative wording. Japanese and English contract review makes it particularly relevant for teams working across both languages.
Its strongest area is the depth of the review workflow. LeCHECK can apply company-specific criteria based on internal templates and rules, compare clauses, display document differences, and suggest redline-style revisions. It also supports contract storage and expiry alerts, extending the workflow beyond a single review. A Microsoft Word add-in connects review and document-correction tasks within Word, while the published category specifications list support for PDF and Word files, clause comparison, redline suggestions, and playbook support.
Pricing is structured around a Free trial, ライトプラン, 基本プラン, and プロフェッショナルプラン. The Free trial includes lawyer-supervised AI risk checking, while the Professional plan lists industry-specific packages, access permissions, and contract version management. Annual plans require contacting sales, and the ¥0 offer is presented as a trial rather than a permanent free plan. LeCHECK suits organizations that value supervised review, internal rules, bilingual contracts, and ongoing contract management. Teams seeking a self-serve product with published plan amounts, a permanent free tier, or broader platform coverage may prefer an alternative.
