When Legal Interpretation Meets AI: A Modern Transformation of an Ancient Profession

Legal interpretation is one of the oldest professions in human history. From Roman jurists to modern law firms, interpreting legal texts, case law, and regulations has always been the core mechanism that keeps legal systems running. Now, Legora co-founder and CEO Max Junestrand is using AI technology to bring this ancient profession into a new era.

Legora chose Anthropic's Claude as its core AI engine, dedicated to building an intelligent tool platform for the legal industry. The logic behind this choice is worth examining — Claude's capabilities in long-text comprehension, logical reasoning, and nuanced analysis align perfectly with the legal profession's demands for precision and deep understanding.

Claude's Technical Advantages in Legal Scenarios

Anthropic's Claude model is trained using Constitutional AI, a technical approach that guides model behavior through predefined principles. Unlike traditional RLHF (Reinforcement Learning from Human Feedback), Constitutional AI enables the model to self-evaluate and correct its outputs during training, making it more inclined to produce accurate, harmless, and honest responses. For legal applications, this means Claude tends to acknowledge uncertainty rather than fabricate answers when facing ambiguous or contentious legal questions — a characteristic crucial for work that demands rigor. Additionally, Claude's long context window (up to 200K tokens) enables it to process complete legal documents, court decisions, or regulatory compilations in a single pass, avoiding comprehension errors caused by text truncation.

Legora's Core Strategy: Building Boats for Everyone

Max Junestrand proposed a remarkably insightful metaphor: every new model release raises the tide, and Legora's job is building the boats for everyone.

This metaphor reveals Legora's business positioning — they don't attempt to compete with foundational large models. Instead, they build application-layer products for legal professionals atop the rising wave of AI capabilities. As each generation of models like Claude achieves new capability breakthroughs, Legora's products rise with the tide, delivering more powerful legal interpretation services to users.

Ecosystem Analysis of the Application-Layer Business Model

In the AI industry value chain, there are typically three layers: the infrastructure layer (compute and chips), the model layer (large language models themselves), and the application layer (products facing end users). Legora's position in the application layer carries unique business logic — it doesn't need to bear the billions of dollars required to train large models. Instead, it accesses model capabilities through API calls, focusing its core competitiveness on structuring domain knowledge, optimizing user experience, and deeply integrating workflows. This model resembles the relationship between app developers and operating systems in the mobile internet era: every OS upgrade brings new capabilities to apps, while the app's value lies in its deep understanding of specific scenarios.

This "application-layer" strategy offers unique advantages in the current AI ecosystem:

Lowering technical barriers: Legal professionals can access intelligent assistance without understanding underlying AI technology
Domain specialization: Deep customization for the legal field delivers more precise services than general-purpose AI
Continuous evolution: When foundational models upgrade, application-layer products automatically gain enhanced capabilities

Market Opportunities and Challenges for Legal AI

Why the Legal Industry Is Particularly Suited for AI Empowerment

The core of legal work — reading, understanding, analyzing, and interpreting large volumes of text — happens to be exactly what current large language models excel at. Traditionally, a lawyer might spend hours studying case law and regulations, while AI can complete initial screening and summarization in seconds, allowing professionals to focus their energy on higher-value judgment and strategy formulation.

Legal interpretation is an extremely complex cognitive process in legal theory, involving the intertwined application of multiple interpretive methodologies. Textual interpretation focuses on the literal meaning of legal provisions, purposive interpretation traces the original intent of legislators, systematic interpretation requires understanding individual provisions within the context of the entire legal system, and historical interpretation examines the historical context of legal evolution. Furthermore, different legal traditions (civil law and common law systems) have fundamentally different methodologies for legal interpretation — civil law systems rely more on logical deduction from codified statutes, while common law systems place high importance on analogical reasoning from precedents. For AI to truly be competent at legal interpretation, it must be able to flexibly apply these different interpretive frameworks and understand the legal traditions and practical conventions of specific jurisdictions.

Trust and Accuracy: The Threshold Legal AI Must Cross

The legal field places exceptionally stringent demands on AI. A single erroneous legal interpretation can lead to serious consequences, meaning AI tools must meet extremely high standards in accuracy, traceability, and transparency. Legora's choice of Claude as its foundational model reflects its appreciation for Claude's design philosophy around safety and reliability — critical for legal application scenarios.

The "hallucination" problem of large language models is one of the biggest technical challenges facing legal AI. Hallucination refers to the model generating information that appears plausible but is actually nonexistent or incorrect — for example, citing nonexistent case law, fabricating false statute numbers, or incorrectly interpreting the applicable scope of legal provisions. In 2023, an incident in the United States where a lawyer submitted fabricated case citations generated by ChatGPT to a court sparked widespread industry discussion about AI reliability. To address this challenge, legal AI products typically employ RAG (Retrieval-Augmented Generation) technology — first retrieving relevant documents from trusted legal databases, then having the model generate responses based on the retrieved results, thereby minimizing hallucination risk. Providing source citation traceability is also an essential feature of legal AI products.

Industry Trends: The AI Wave in Legal Technology

Legora is not alone. The global LegalTech sector is undergoing a profound AI-driven transformation. From contract review to legal research, from compliance monitoring to litigation prediction, AI is penetrating every aspect of legal work.

The Global LegalTech Market Landscape

The global legal technology market is in a period of rapid growth. According to Grand View Research, the market is projected to exceed $35 billion by 2030. Before the AI wave, the first wave of LegalTech innovation primarily focused on areas such as eDiscovery, Contract Lifecycle Management (CLM), and practice management software, with representative companies including Relativity, DocuSign, and Clio. AI-era LegalTech is more focused on cognitive-level automation — not just process digitization, but attempting to replicate the analytical and judgment capabilities of legal professionals. Harvey AI, CoCounsel (launched by Casetext, acquired by Thomson Reuters), and Europe's Luminance are all significant players in this space.

But Legora's uniqueness lies in its focus on the core capability of "legal interpretation." Legal interpretation is not merely text search or simple summarization — it requires understanding legal logic, grasping legislative intent, and considering judicial practice. These are precisely the areas where the new generation of AI models is beginning to demonstrate breakthrough capabilities.

Outlook: Dual-Engine Growth Through Model Evolution and Application Deepening

Max Junestrand's "rising tide, building boats" theory points to an important trend: as foundational AI capabilities continue to improve, true value creation will increasingly occur at the application layer. For the legal industry, this means future competition is not just about technology, but also about the depth of understanding of legal expertise and user needs.

Legora's practice provides us with an observation window — when the oldest profession meets the most cutting-edge technology, the space for innovation may be far greater than we imagine. For practitioners focused on legal technology and AI application deployment, Legora's development trajectory is worth continued attention.
