Pairing the most advanced AI legal reasoning engine with the most comprehensive U.S. case law database, Callidus delivers end-to-end litigation automation that outpaces legacy platforms
(PRUnderground) May 19th, 2025
Callidus Legal AI, the AI platform that automates & accelerates attorneys across core legal workflows, today announced its most advanced legal research and drafting system to date—powered by proprietary engineering, agentic AI, and a fully integrated U.S. case law database.
As AI transforms industries, legal work is emerging as one of the most ripe for disruption. Goldman Sachs estimates that 44% of legal tasks could ultimately be automated by AI. However, more than a third of litigation hinges on deep legal understanding, especially in research and drafting, where shallow, chatbot-style AI falls short. Compounding the challenge, legal case data is notoriously locked down. Westlaw and Lexis, each valued at around $60 billion, built their dominance by employing armies of attorneys over decades to annotate cases with detailed metadata, like material facts and legal holdings, essentially creating cliff’s notes for every ruling. They aggressively protect this data, making it nearly impossible for startups to compete due to the necessities of comprehensiveness and accuracy in legal research.
That’s where Callidus breaks new ground: Leveraging partnerships to gather over 10 million U.S. legal cases, Callidus has spent the last year building specialized agents to enrich this database with detailed metadata, case summaries, and issue-based tagging in a way that is purpose-built for high-precision retrieval and research in an AI world.
“Legal reasoning is highly nuanced – you can’t do anything valuable in litigation until you understand the law, and to do that in an automated way, you need both a deeply engineered agentic AI middle-layer and a comprehensive case database,” said Justin McCallon, CEO and co-founder of Callidus Legal AI. “While other companies are adding features to legacy platforms, Callidus is rethinking the entire vehicle. Our platform is built from the ground up for the AI-native legal world. Our platform doesn’t just answer questions, it thinks like a lawyer while synthesizing high volumes of text-based data.”
By building its own case law database and engineering powerful retrieval systems, Callidus is able to add the most critical chess piece to its legal research system and can now provide comprehensive and extensive case suggestions for every element in a new matter. The highly visual and interactive Callidus research system keeps the lawyer in the loop, with the AI synthesizing robust data and the lawyer making strategic decisions, ultimately condensing a typical week-long task into about 10 minutes for 85% completion. From there, the lawyer can polish the full litigation outlines and extensive litigation draft document outputs with other Callidus tools, integrated with Microsoft Word, to prepare final versions for court.
The legal industry is rapidly evolving and large language models (LLMs) are advanced enough to create ideal solutions for attorneys. Unlike competitors that rely on chatbots and generate brief, high-level answers, Callidus produces work-product-caliber outputs. These include exhaustive precedent research, element-by-element legal outlines, and fully drafted, citation-ready litigation documents often exceeding 30 pages. The company’s AI litigation offering is built to handle complex workflows end-to-end, enabling real impact in law firms of all sizes. Over the next few months, Callidus will be optimizing and layering in new capabilities to its solution to ensure lawyers are equipped with the best tools to do complex work.
