Four Real Legal AI Use Cases
The easiest legal AI wins are not automated litigation but four repetitive tasks: contract review and clause comparison, legal research and case summaries, due diligence and document review, and compliance Q&A. They share document inputs, citation requirements and high error costs. Evaluate traceable statute/case sources, Chinese legal coverage and private deployment before generation speed.
Chinese Legal Tools: Research, Contracts and E-signature
For Chinese legal research, start with PKULaw, Wolters Kluwer, ItsLaw and DeliLegal for broader statutes and cases. Contract review can use MeCheck, Tongyi Farui and Thunisoft to encode review rules into workflows. E-signature and contract management tools such as Qiyuesuo, Fadada and Junziqian matter less for generation and more for signing compliance, evidence retention and permissions. If legal already has an OA or contract system, prioritize integration over rebuilding around an AI feature.

Choosing for International Firms and Contract Teams
International firms and large legal teams often need research, review and contract lifecycle coverage: Harvey spans research, drafting and review; Lexis+ AI and vLex Vincent leverage authoritative databases and citations; Ironclad, Evisort, LinkSquares, LawGeex, SpotDraft and Juro cover contract lifecycle; EvenUp focuses on personal injury demands; ClaimMaster and PatentPal serve patent drafting and prosecution. Validate citation traceability, permission isolation, whether data trains the model and integration with the existing DMS.

Risk: Confidentiality, Hallucination and Liability
Three red lines: first, client materials and unpublished deal information must not enter public models that train on data; confirm terms or use private deployment. Second, every cited statute and case must be verified—models invent plausible docket numbers. Third, AI output is supporting material, not a substitute for professional judgment or signing responsibility. Establish an AI draft → lawyer review → citation check → archive workflow and retain prompts and model versions.
Start with One High-Frequency, Low-Risk Use Case
Do not start with end-to-end legal AI. Pick one high-frequency, low-risk, verifiable task such as NDA clause comparison, regulatory update summaries or contract renewal reminders. Use 50 historical documents as a baseline and compare AI findings with lawyer findings, logging misses and false positives. Then expand to procurement contracts or labor compliance. For each scenario, define when human review is mandatory and write responsibility into the process.
