Artificial Intelligence (AI) is substituting human decision-making in every aspect of life where law stands with no exception. New technological trends offer expeditious and cost-effective AI tools yet confront challenges such as privacy invasion, bias, fairness, and hallucinations, necessitating regulatory oversight. Like other countries, the USA and Pakistan have initiated AI solutions in their legal domain. A strong regulatory oversight is indispensable for its legitimacy and efficiency. Based on their functions and ethical considerations, AI tools in the legal profession face competing opinions. With qualitative research methodology, the research aims to explore how AI is transforming and reshaping the legal regime, focused on the comparative analysis of the USA and Pakistan. The research paper critically examines the legal frameworks and impacts of AI solutions and how both countries navigate the complexities of AI-based decision-making.
