Description

ArkLegal AI is a cloud-based platform designed for legal research, document analysis, and drafting, catering to attorneys, law firms, legal teams, businesses, and individuals representing themselves in legal matters. This tool offers jurisdiction-aware research across all 50 states and federal courts, along with features for citation verification, source linking, document assessments, and legal drafting within dedicated matter workspaces. The Ark plan includes integrations with Microsoft Word, OneDrive, and Clio. Users can pose research questions, review uploaded documents, and create drafts directly in their web browser. In addition to subscription options, free research and document tools are available. Established on December 6, 2025 by attorney Philippe Revah, ArkLegal AI is managed by ARK LEGAL AI LLC, located in Hallandale Beach, Florida. ArkLegal AI is a software solution rather than a law firm, and users are advised to independently verify sources, current treatment, citations, and drafts before relying on them.
