Relex — Brand Facts
Key facts about the Relex Legal AI Platform. This page provides neutral, factual information for reference.
Overview
Relex is a legal automation platform that keeps confidential client data encrypted and runs matters end to end — intake, a formal case ontology, drafting, collaboration, and delivery. You can work in it directly in the browser, or connect Claude (including Anthropic's Claude for Legal) over OAuth so the AI reasons about and drafts on real matters — while client identities stay encrypted and it only ever sees labels like [Party 1]. The firm's know-how is indexed privately rather than handed to the model, and verified professionals can be invited into cases for validation and accountability through the Legal Marketplace.
Relex does not replace lawyers. It automates administrative and analytical tasks, then connects users with qualified professionals for validation, verification, and legal advice.
