“A Survey Paper on LegalSphere – Your AI-Powered Legal Companion”

Abstract. The complexity of legal terminology and the limited availability of affordable professional support often hinder access to legal knowledge in India. LegalSphere – Your AI-powered Legal Companion – aims to bridge this gap using Natural Language Processing (NLP) and machine learning techniques. This paper surveys AI and NLP-based approaches to democratize legal access by simplifying legal language, offering intelligent query handling, and providing case-specific responses grounded in Indian laws and regulations. The paper compares transform-based models like BERT and RoBERTa in legal NLP applications and highlights system architecture, dataset strategies, and practical use cases for LegalSphere.
