DeepLegal: Agentic AI RAG for Legal Research
"In the legal sector, accuracy is non-negotiable. DeepLegal allows us to offer our clients a tool that not only accelerates research, but guarantees full source verifiability and the highest security for sensitive data."
Challenge
Lawyers dedicate a substantial amount of their time to manual research across regulations, rulings, and case law precedents. This process is fundamental to building solid arguments, but it is also:
Time-consuming. Hours of research in legislative archives and case law databases to find relevant references;
Prone to incompleteness. The risk of failing to identify relevant precedents or applicable regulations;
Difficult to scale. As the volume of laws and rulings grows, manual research becomes progressively less sustainable.
The legal sector needed an intelligent assistant for research and brainstorming that could:
Rapidly query enormous volumes of legal documents;
Provide accurate answers with verifiable citations;
Maintain the highest security and regulatory compliance for sensitive data.
DeepCloud is a Swiss company specialising in technology solutions to streamline business services and performance. With DeepLegal, DeepCloud set out to create a platform dedicated to the legal sector, combining artificial intelligence with the rigorous precision demanded by legal and jurisprudential practice.
Our AI Solution
Artificialy supported DeepCloud in the development of DeepLegal, a platform based on an Agentic RAG (Retrieval-Augmented Generation) architecture that transforms the way lawyers conduct legal research.
Key components of the solution:
Knowledge base curated from 800,000 documents. A massive database querying all official Swiss laws and rulings from 2000 onwards, with over 10 million structured metadata entries to ensure precise and contextualised searches;
LLM optimised for the legal context. A language model fine-tuned specifically for legal use cases, trained to understand legal terminology, argumentative structures, and regulatory logic;
Parallel multi-agent pipeline. Rather than a single processing flow, DeepLegal employs a complex architecture in which several specialised AI agents work in parallel: a query expansion agent that analyses the user's question and breaks it down into sub-searches; parallel retrieval agents, one focused on legislation and the other on case law; a citation validation agent, which filters out irrelevant references and verifies source accuracy; and finally, a synthesis agent, which aggregates results from the various agents and generates a structured response.
Zero data movement & on-premises deployment. The entire system runs locally on infrastructure hosted in Switzerland, ensuring that sensitive data is never moved or exposed to external jurisdictions.
