As legal systems grow increasingly complex and AI capabilities rapidly advance, South Korea’s Law&Company Co., Ltd. is charting a new course for legal productivity and access. Known as Korea’s No. 1 legal tech company, Law&Company has steadily built a legal ecosystem over the past decade—spanning a comprehensive legal portal, a legal research service, and now, a GenAI-powered legal assistant.

At the heart of its latest expansion is SuperLawyer, Korea’s first generative legal AI service, developed to support legal professionals with fast, verifiable legal research and document generation rooted in deep legal understanding.

After achieving rapid adoption in Korea, SuperLawyer is now preparing to launch its Japanese-language version. Through upcoming strategic partnerships and enterprise collaborations, Law&Company aims to provide Japanese legal professionals with AI tools that stream various legal works.

SuperLawyer: Generative AI service for Lawyers—Built with Legal Precision

Unlike general-purpose AI tools, SuperLawyer is purpose-built for the legal profession, drawing on proprietary data architecture and natural language processing optimized for the nuances of legal reasoning, citation, and precedent.

Key Capabilities:

• AI Legal Research: Accesses 5 millionlegal precedents, statutes, and interpretations to deliver fast, citation-linked answers.
• Document Drafting Automation: Generates contracts, pleadings, and legal filings with formatting aligned to court and practice standards.
• Case File Analysis: Enables legal professionals to pose complex queries across diverse case documents, supporting not just summaries but also structured organization, in-depth analysis, and comprehensive review.
• Citation Verification Engine: Provides lawyers with instant validation of legal sources through Law&Company’s citation-checking technology, currently under patent application.
• Hallucination Minimization: Uses proprietary Korean legal data and RAG (Retrieval-Augmented Generation) techniques to dramatically reduce inaccuracies. It also provides source links, a built-in fact-checker, and AI agent technology to ensure that responses are grounded in verifiable data.

With its “SuperLawyer architecture” and domain-specific training, the platform is designed to assist—not replace—legal professionals, offering AI-powered productivity that complements legal expertise.

Strategic Partnerships and Active Engagement in Japan

Law&Company is not new to the Japanese legal market. In 2025, it formalized a business agreement with LexisNexis and initiated partnership discussions with leading Japanese legal tech firms. These engagements reflect Law&Company’s focus on local integration—not just export.

Planned models for collaboration include content licensing agreements with legal publishers and joint platform initiatives with legaltech companies that want to integrate GenAI-powered legal assistant.

SuperLawyer: Proven Legal AI Built for Real-World Use

SuperLawyer has already earned adoption among Korea’s major law firms, in-house legal departments, and public institutions, where it’s used for legal advisory, litigation support, and internal compliance.

• SuperLawyer achieved 82% accuracy (top 5% percentile) on the Korean Bar Exam’s multiple-choice section in May 2025, surpassing its own record—a first for a non-English AI model.
• Recognized for its proprietary citation-checking technology—currently under patent application—which enables legal professionals to instantly validate sources and precedents within AI-generated responses.
• Continuously updated with new precedents, regulatory standards, and interpretive changes—providing legal teams with current, compliant data at all times.

Expanding AI Legal Infrastructure Through Strategic Localization

With foundational partnerships and pilot discussions already in motion, Law&Company’s Japan strategy now shifts to deepening collaboration and enabling local legal tech innovation.

Law&Company has steadily advanced Korea’s legal tech landscape over the past decade—launching its comprehensive legal portal in 2014, establishing a dedicated Legal AI Research Lab in 2019, and developing a legal-specialized language model in 2020.

Its flagship generative AI service, SuperLawyer, debuted in 2024 and, within just one year, has already been adopted by approximately 38% of Korea’s practicing lawyers, underscoring both its rapid traction and market relevance.

As Japan’s legal sector explores ways to modernize workflows without sacrificing accuracy or confidentiality, SuperLawyer positions itself as a domain-trained AI assistant—offering legal professionals a reliable, scalable entry point into AI-powered operations.
