LexiHK
Legal AI research and evaluation.
Overview
LexiHK is a home-grown legal AI tool developed with the Hong Kong Generative AI Research and Development Centre (HKGAI) for Hong Kong’s bilingual common-law environment. It provides a platform for translating research into practice: researchers examine source verification, reliable reasoning and human–AI collaboration in real legal workflows, while the product team uses practitioner feedback to improve the system. Product development and operations are separate from the Center’s research platform.
Functions and Professional Practice
Built for local legal practice, LexiHK incorporates more than 200,000 statutory and case-law records. Its functions include legal chat, retrieval, case research, drafting, contract review, document interpretation, legal agents and visual search, supporting government, arbitration, law firms and businesses. Legal question-answering accuracy exceeds 90%, with an emphasis on traceable citations and human review of generated results.
Professional Practice and Education
Legal work depends on judgment across facts, rules and specific contexts. Human–AI collaboration is central to the team’s approach: while improving retrieval, document processing and case research, it preserves opportunities for junior practitioners to analyse independently, reason fully and receive feedback, enabling professionals to focus on work requiring experience and judgment.
Media and Recognition
Thomas So, a member of the National Committee of the CPPCC and Hong Kong’s Legislative Council, discussed LexiHK in his China Daily article “AI empowers transformation of Hong Kong’s legal industry”, including its local development and planned Department of Justice trial. UNWIRE.PRO also discussed LexiHK in coverage of legal technology and education, stressing professional training, judgment and responsibility for reviewing outputs. LexiHK Legal AI Assistant received a bronze medal at the 50th International Exhibition of Inventions Geneva in 2025.
