Yuan Dian Zhi Ku
An AI-powered legal knowledge platform that helps lawyers, judges and other legal professionals quickly perform similar case searches, regulation lookups, and sentencing analysis.
Tool overview
Yuan Dian Zhi Ku integrates over 150 million judgments and 4.07 million laws and regulations, enabling in-depth case linkage and semantic search. It automatically recommends key factors such as disputed issues and rulings, significantly reducing the time spent on case research and legal retrieval.
Advantages include broad data coverage, multi-dimensional tools like judge analytics and sentencing analysis, and the ability to find substantively identical cases despite different wording, improving both recall and precision.
The main drawback is the risk of “legal hallucination,” i.e., fabricated law articles or content that must be verified against original texts. Currently, only a time-limited free trial is offered, with no publicly disclosed post-trial pricing, leading to cost uncertainty. Using the platform effectively requires legal expertise, otherwise it is difficult to assess the quality of search results.
It suits practicing lawyers, judges, prosecutors, in-house counsel, and law students who frequent case research.
