Frontier legal AI (cloud)
EdgeLex vs. Harvey
Harvey is a frontier legal-AI platform used by many of the largest firms. EdgeLex's distinction is deployment choice and a complete operational stack.
Harvey is a powerful, enterprise-grade frontier legal-AI platform used by many of the world's largest firms for research, drafting, document analysis, and agentic workflows, hosted across multiple regions.
Harvey is an AI layer, not a system of record: it does not provide matter management, billing and trust accounting, court-rule deadlines, intake, or self-hosted email — and it runs only in Harvey's cloud. EdgeLex is a complete legal platform that includes those operational systems and can be deployed in our cloud, your private cloud, or fully self-hosted.
Both ground answers and gate agent actions. EdgeLex's distinction is that grounding runs against your own documents, emails, court rules, and a firm-curated case library inside infrastructure you choose, with default-deny model governance and the option to run local models — control a cloud-only platform cannot offer.
