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.

About

Gone are the days of questionable citators, frustrating search results, and limited legal research databases. Decisis cuts through the noise to give you everything you need to win your case- and nothing you don't. With a clean intuitive interface and lightning-fast, reliable results, Decisis is the clear choice for bar associations or 1-2 attorney firms. The comprehensive and reliable legal research database you've been looking for. With most free legal research solutions, you can never be certain the case you find is still good law due to their inferior citators. Decisis offers users a world-class citator that’s more effective and robust than Fastcase or Casetext citators. Poor UI, search filtering, and search relevance can put an ocean between you and the single case you need to support your argument. With Decisis, you get a streamlined legal research solution with tailored search filters to pull highly relevant results from a massive primary law database.

AI Legal Supported

ArkLegal AI combines multiple language models with citation-focused retrieval for U.S. legal work: research answers, case agents, matter workspaces with document uploads, drafting with DOCX export, and integrations with Clio, Microsoft Word and OneDrive. The running cost of every chat and matter is shown as you go.

Legal Research Supported

ArkLegal AI searches case law, statutes and regulations across all 50 states and federal courts, returning answers with source links and supporting passages. Its citation verification checks that each cited authority exists, is accurately cited and has not been flagged as overruled or superseded, with the citing court's passage shown behind each treatment flag.
