ArkLegal AI provides AI-assisted U.S. legal research, citation checking, document analysis and drafting on Android, iOS and the web. It searches available state and federal opinions, statutes, court rules and specialized official legal materials, with coverage varying by source, jurisdiction and date. Citation checks provide links when records resolve, but users should independently confirm authorities before relying on them. Matter workspaces organize research and uploaded documents, allow custom instructions, and offer litigation or transaction modes. Research responses can be exported as formatted DOCX files. The Ark plan lists integrations with Clio, Microsoft Word and OneDrive. A free account includes two AI legal research queries total, with no credit card required; eight free tools cover citation checks, case summaries, PDF preparation, OCR and document extraction, with varying limits. The Law Database + AI Doc Synthesizer plan is $39.99/user/mo and excludes AI legal research chat, case agents and matter workspaces. Ark says conversations, responses and uploads are encrypted at rest with AES-256, but it has not completed a SOC 2 Type II audit.
