THE AUTHORS:
Ayushman Dash, Head of Data and AI at Jus Mundi
Legal research in international arbitration has never been more complex. As cases span multiple jurisdictions, involve thousands of documents, and demand precision that can make or break million-dollar disputes, arbitration professionals are pushing the boundaries of what’s possible with AI-powered research tools.
That’s why Jus AI recently underwent a significant strategic update to meet the rising expectations of arbitration professionals who demand research capabilities that match the complexity of their work.
We sat down with Ayushman Dash, Head of Data and AI at Jus Mundi, to understand the challenges driving this upgrade and what it means for arbitration practitioners, tech leaders, and knowledge managers navigating today’s legal landscape.
The Growing Complexity Challenge
The challenges facing arbitration professionals today really come down to scale and complexity, Ayushman explains.
“We’re talking about sheer volume. The reading list for a single matter can run to tens of thousands of pages. Then you have fragmented sources where arbitration materials live in national courts, institutional websites, and private databases that don’t talk to each other.”
Add to this the security anxieties around confidential data and language mismatches across cross-border cases, and you have a perfect storm of research challenges.
Where Generic AI Tools Fall Short
The team watched users struggle with existing AI solutions, and users tell us that, “It doesn’t think like a lawyer.”
That’s because most tools lack legal reasoning. They summarize text but can’t interpret legal nuance. They often hallucinate facts, miss citations, and give answers that feel surface-level rather than soundly reasoned.
“Legal research starts broad before narrowing down,” explains Ayushman. “To do that well, AI must understand and interpret dozens of metadata points – courts, arbitrator names, procedural dates, even document types. We track over 15 metadata fields per case, and even more per document. That depth is essential.”
The Arbitration Research Challenge
Arbitration presents a unique challenge for any AI: the need to balance precision (how accurate the hits are) and recall (how many relevant documents are uncovered).
The answer isn’t just about search. It’s about semantically understanding the user’s intent, cross-matching it against multilingual, multi-format legal data, and using structured metadata to unearth what matters.
“A query in French might relate to a German-language award buried in an obscure institution’s archive,” Ayushman notes. “It’s not enough for AI to process language, it must reason like a legal expert to surface that document.”
Raising the Bar to Meet Growing Expectations
Jus AI has always been designed with arbitration professionals in mind – blending legal logic with deep data. But as your expectations have evolved, so have we. The demands of modern legal practice now call for a tool that could think like a lawyer, deliver results with transparency, and handle increasing amounts of context in one go.
The result of that vision? A re-engineered Jus AI that reflects the reality of today’s arbitration work: high stakes, high complexity, and high expectations.
The Strategic Upgrade
The expectations around AI in arbitration are rising and Jus AI is evolving to meet them. This upgrade is about building on a solid foundation to deliver even more powerful, reliable, and context-aware legal intelligence.
We’ve taken significant steps to enhance how Jus AI reasons, searches, and responds.
A Step-by-Step Legal Reasoning Process, Built for Arbitration
We’ve upgraded how Jus AI reasons through legal questions by teaching it to think step by step, much like an arbitration lawyer. It now breaks down your query, analyzes relevant sources, applies legal logic, and builds more precise, well-structured answers.
“We’ve trained the AI to think like an arbitration expert – not just retrieve information, but reason through it,” explains Ayushman.
This method also improves how Jus AI explores our database, using document schema and metadata to expand its reach – delivering more comprehensive, context-aware results. Thanks to a 500% increase in context window, it can now analyze significantly more content at once, including user uploads, without losing focus or legal relevance.
Jus Mundi’s Legal Data to Our Advantage
What sets Jus AI apart is the data it’s built on. Jus Mundi’s database combines structured legal documents with exhaustive metadata, giving the AI a clear edge when it comes to accuracy and depth.
“This gives Jus AI a major advantage over other AI assistants when it comes to precise legal research,” says Ayushman. “It’s crucial for finding the needle in the haystack.”
This structure doesn’t just improve search – it enables smarter use of machine learning to anticipate user queries, fine-tune system behavior, and deliver results that reflect the real complexity of arbitration work.
Real Impact
The latest upgrade to Jus AI delivers measurable improvements where it matters most: legal accuracy, research depth, and speed. Whether you’re analyzing precedent or preparing a draft, you’ll experience faster, more intelligent support – every step of the way.
Unlock Deeper Legal Insight
Jus AI now draws on a significantly broader set of documents, both from the Jus Mundi database and your own uploads – to build more context-aware answers. This means your results are no longer based on just a few examples, but on a deeper, more representative view of relevant legal sources.
Rely on Smarter, More Transparent Sources
Improved legal reasoning means better source selection. Jus AI now chooses citations with greater accuracy and logic, reducing noise and increasing transparency. You’ll not only see where the answer is coming from, but also why those sources matter.
Accelerate Your Workflow
With cleaner formatting, clearer structure, and more consistent outputs, you’ll spend less time editing and more time doing. Whether you’re drafting internal notes, preparing client memos, or summarizing case law, Jus AI helps you move faster, without sacrificing quality.
“These improvements work together,” Ayushman notes. “It’s not just about speed. It’s about giving you confidence that the research is comprehensive, the sources are reliable, and the output is ready to support your legal work.”
Looking Ahead: The Future of Legal AI
The doors this upgrade opens for Jus AI’s future development are significant. “Major upgrades ahead,” Ayushman reveals. “A new foundational language model with stronger multilingual and legal-reasoning skills. A Deep Research mode powered by an AI agent that navigates our database, the web, user documents, arbitrator profiles, and more.
Beyond Traditional Research
The vision extends beyond traditional research. “We’re building capability to plan, execute, and evaluate unknown use cases using the entire Jus Mundi database. Tools for complex workflows like timeline extraction from case documents, full document translation, profile search… these will all be part of the new releases.”
The Ultimate Vision
Reflecting on what this upgrade represents for the future of legal AI, Ayushman’s vision is both ambitious and clear: “We believe the current version of Jus AI is only the start. We have learned from users, gathered feedback, and assembled a team with decades of AI research experience.”
As Ayushman, puts it:
“It should solve complex legal research tasks at a scale no human can match, leaving users saying, ‘I could not have done that myself.’”
The future of legal research isn’t just faster. It’s smarter. And it’s already here.
