In recent years, Artificial Intelligence (AI), including the emergence of ChatGPT, has attracted significant attention due to its increasing prevalence in several aspects of business processes. AI involves the development of automated systems capable of executing tasks traditionally performed by humans, with the aim of speeding up processes and reducing wasted time within organisations. This technology has also opened significant opportunities for application in the legal sector, traditionally engaged in analysing large amounts of documentation. This Master's thesis explores the use of Large Language Models (LLM) to support legal staff and reduce document management time. The aim of this research is to study, design, develop a POC (proof of concept) to address these challenges by implementing a web application where lawyers can analyse contracts e generate contract.
