A free account includes two total AI legal research queries without a credit card, and eight free tools cover citation checking, case summaries, PDF preparation, OCR and document extraction, with limits varying by tool. The Law Database + AI Doc Synthesizer plan costs $39.99 per month and excludes AI legal research chat, case agents and matter workspaces; The Ark plan costs $89.00 per month.

CaseCraft is legal research software that creates research memos using multiple LLM models, traditional machine learning, curated filters, and proprietary legal data. Users can set state, federal, or tribal jurisdictions, with research drawing on millions of cases. The maker says its collection of rule statements is intended to reduce hallucinations and ties answers to real cases. Users can upload contracts, leases, and licenses for analysis against relevant law. ChatCraft supports due diligence by finding case parentheticals, comparing rules, and extracting legal meaning. Judge-specific search lets users examine opinions and estimate their odds of prevailing. Listed subject areas include contracts, torts, and property, while primary-source coverage includes case law, statutes, and regulations. Some features consume credits per use. New users can get 10 free credits by downloading the app and registering a new phone number. CaseCraft runs on Android, iOS, and the web. Monthly plans range from $10 a month to $299 a month for the listed lawyer plan; one-time credit packs range from $4, paid once to $100, paid once.
