Law&Company transforms legal services in South Korea with Claude
Law&Company uses Claude to power SuperLawyer, South Korea's first AI legal assistant that helps lawyers reduce time spent on legal research and document preparation while maintaining high accuracy for sensitive legal work.
With Claude, Law&Company:
- Attracted 6,000 users—20% of South Korean Practicing lawyers—within 180 days
- Achieved a 60.2% free-to-paid conversion rate and a 79.1% second-month retention
- Helped lawyers increase efficiency 1.7x, saving 25 minutes per hour of work
- Enabled legal teams to save over 2.3 million collective work hours in the first 180 days
Addressing inefficiencies in legal services
The legal industry faces the challenge of handling complex cases while managing routine document preparation and research. In South Korea's legal sector, lawyers struggle to balance client meetings and court appearances with time-consuming documentation tasks. For many firms, a single case requires hours of research and document preparation, creating bottlenecks that limit their ability to serve more clients.
Law&Company recognized that AI could transform workflows while maintaining the high standards of accuracy essential in legal work. Their goal was to help legal professionals focus on high-value tasks by automating routine document work without compromising the precision required in legal services.
Why Law&Company chose Claude
After evaluating multiple AI models, Law&Company selected Claude for its superior performance in Korean legal documentation and robust technical capabilities. "Claude demonstrates exceptional capabilities in generating Korean legal documents. Its advanced knowledge and understanding of legal matters, combined with extensive training in Korean enables it to outperform other models in producing high-quality legal writing," said Bon-hwan Kim, CEO of Law&Company.
Claude's ability to minimize AI hallucination was crucial for handling citizens' fundamental rights. Law&Company implemented a sophisticated Retrieval Augmented Generation (RAG) system that allows Claude to reference relevant legal data before responding. Claude's function-calling capabilities help organize information in the needed sequence for each unique user request.
How Claude powers SuperLawyer
Law&Company built a flexible architecture for SuperLawyer that could accommodate various AI models while enabling easy updates to system prompts and experiments with diverse data implementations. While the initial architecture development required significant effort, implementing Claude within this framework proved straightforward. The team continues to fine-tune Claude's system prompts to optimize performance according to their standards.
SuperLawyer uses Claude to streamline key aspects of legal work:
- Legal research and precedent analysis
- Document drafting and creation
- Case law summarization
- Document-based conversation
- Regulatory compliance checking
The platform initially faced scaling challenges as user numbers surged, requiring an expansion of API usage limits. However, with support from Anthropic's customer service team, they quickly resolved these issues to maintain service reliability.
Delivering measurable impact
The success of SuperLawyer demonstrates AI's potential in legal services. Survey results show 92.5% of users saved time, with 46.8% saving over 30 minutes per hour of work. Additionally, 70% reported cost savings, with 30% noting a "meaningful reduction in costs."
The impact extends far beyond simple time savings. A partner attorney with 15 years of experience said, "Tasks that used to take 3 hours to 2 days now take minutes, allowing me to devote more time to high-priority tasks." For independent lawyers, the impact is even more dramatic. One solo practitioner explained, "SuperLawyer enables the modularization of case handling—it's like how a single developer using Claude can be as effective as a team of 10 junior developers."
Recent improvements, including the adoption of Claude 3.5 Sonnet, have reduced response times by over 40% while maintaining high accuracy. This upgrade allows Law&Company to better serve their rapidly growing user base.
The future of AI in legal services
Law&Company sees AI as key to democratizing legal services in South Korea. Building on SuperLawyer's success, they plan to extend Claude's capabilities across their product suite, including LawTalk, their premier legal portal with 1.3 million monthly visitors, and Big Case, their comprehensive legal information service.
Law&Company secured an exclusive supply contract with Park Young Sa, South Korea's leading legal publishing house, to enhance their AI capabilities. This partnership will improve response quality and reliability by leveraging expert legal content. Furthermore, Law&Company is focused on rapidly advancing their service to reduce AI hallucination. Recently, They've implemented a citation appropriateness evaluation feature to mitigate hallucination.
"We believe that introducing generative AI technology to provide essential and valuable solutions within the actual workflows of legal professionals will naturally enhance consumer convenience," said Kim. Through their expanding partnership with Anthropic, Law&Company aims to innovate in legal technology while maintaining their commitment to accuracy and efficiency in legal services.
