International law and arbitration research platform Jus Mundi today (10 September) announced the launch of Jus AI 2, its second generation arbitration agent.
Jus Mundi was founded in 2019 and is used by leading firms including Freshfields, A&O Shearman, White & Case, Quinn Emanuel, Three Crowns, Wong Partnership, and Al Tamimi.
One year after launching Jus AI – its AI assistant built for legal & arbitration professionals, we’re told that Jus AI 2 now combines agentic reasoning with deterministic search control.
Jus Mundi says that the solution’s new AI planning agent creates a multi-step research plan tailored to each query. It then analyses up to 75,000 documents per minute, identifying the most relevant legislations, precedents, and publications from all over the world. Finally, it delivers a structured, actionable answer, with transparent reasoning and specific source documents.
“While AI is probabilistic by nature, arbitration professionals need certainty when million-dollar disputes hang on procedural nuances,” said Jean-Rémi de Maistre, CEO and Co-Founder of Jus Mundi. “Jus AI 2 eliminates the compromise between speed and control. For the first time, practitioners can leverage agentic AI reasoning while maintaining complete oversight of their research sources.”
Jus AI 2 is said to achieve a 125% increase in retrieval relevancy compared to traditional legal research tools.
Jus AI 2 draws from Jus Mundi’s database spanning awards, treaties, rules, exclusive data from partnerships with leading arbitral institutions and associations, including IBA, ICC, AAA-ICDR, DIAC, HKIAC, and CAM-CCBC, as well as secondary sources from leading publishers like Oxford University Press, JURIS, and Brill.
“This breakthrough goes beyond arbitration,” said de Maistre. “We’ve proven that Agentic AI-powered legal research can meet the quality standards legal professionals actually need. What started as arbitration intelligence is now the foundation for legal intelligence across every practice area.”
Jus Mundi will demonstrate Jus AI 2’s capabilities during a live webinar on September 11, 2025, at 4pm CET / 10am ET. To join the webinar, register here.
