LegalOn
LegalOn Technologies is a legal-technology company building AI software for in-house legal teams, corporate legal operations, and law firms. Its platform covers AI contract review and redlining, contract playbooks, matter management, a contract data vault, translation, entity and board management, and agentic legal workflows, with a Microsoft Word integration for reviewing agreements in place. Founded in Japan as LegalForce and now operating in both Japan (legalontech.jp) and the United States (legalontech.com), the company runs a sibling product family for governance (GovernOn), sales (DealOn), HR (WorkOn), and marketing compliance (DocumentOn). LegalOn publishes a REST API for contract files and contract metadata — upload, retrieve, update and delete contract documents, register and update contract information such as counterparties and contract types, link related documents, and list registered contracts — authenticated with OAuth 2.0 client credentials, intended for integration with contract management systems, CRM, and BI tooling. The API is announced publicly but its reference documentation is not published on the open web; access is arranged through the vendor. The company is backed by Hongshan and the SoftBank Vision Fund, and publishes SOC 2 Type II, ISO/IEC 27001:2022 and ISO/IEC 27017:2015 certifications through a public trust center.
LegalOn is listed with 1 API on the APIs.io network. Tagged areas include Company, Technology, Legal, Legal Tech, and Contracts.
LegalOn’s developer surface includes engineering blog, pricing, changelog, support, authentication, and 21 more developer resources.
