About

ArkLegal AI is a cloud-based U.S. legal research, document analysis and drafting platform for attorneys, law firms, legal teams, businesses and self-represented users. It supports jurisdiction-aware research across all 50 states and federal courts, citation checks and source links, document review, legal drafting and matter workspaces. Microsoft Word, OneDrive and Clio integrations are included in the Ark plan. Users can research questions, analyze uploaded documents and develop drafts in a browser. Free research and document tools are available alongside paid subscriptions. Founded on December 6, 2025 by practicing attorney Philippe Revah, ArkLegal AI is operated by ARK LEGAL AI LLC in Hallandale Beach, Florida. ArkLegal AI is software, not a law firm. Users should independently review sources, current treatment, citations and drafts before relying on results.
