GVA NDAチェック vs LegalCheckPro

GVA NDAチェック is a free AI-powered contract review service supervised by lawyers, specifically designed for checking NDA (Non-Disclosure Agreements). It allows users to upload contracts, receive risk assessments (unfavorable, neutral, favorable) and clause-level modification suggestions. The service aims to help SMEs and freelancers without dedicated legal teams to review contracts efficiently. It has been adopted by over 400 companies and 1,000+ freelancers, and has received awards like the Nikkei Excellent Products and Services Award.

LegalCheckPro is an AI-powered contract review service that turns dense, complicated legal documents into clear, ranked PDF reports. Instead of wading through pages of legal jargon, users upload their contract, choose the document type and their role, and receive a digestible breakdown of top risks, highlighted clauses, and practical recommendations. The service focuses on making legal insight accessible to people who may not have a lawyer on call, with plain-language output and a fixed $6.99 price per document. The platform supports common agreements such as rental agreements, employment contracts, NDAs, service contracts, and sales contracts, while claiming coverage across US, EU, UK, and APAC jurisdictions. Its AI is trained on millions of legal documents, and every analysis is fact-checked by a legal professional before it is delivered. Users receive an email notification once the report is ready, typically within about 1.5 hours, and can request a refund if they are not satisfied with the result. Privacy is a core part of the offering: uploaded documents are encrypted, automatically deleted after analysis is sent, and personal data is hidden in generated reports. The service is aimed at tenants, landlords, employees, employers, freelancers, and small businesses that need a fast, low-cost second opinion before signing an agreement. A sample report is available for preview, and enterprise customers can contact the team for custom pricing and future collaboration features.
