Abstract: Text extraction from unstructured documents presents significant challenges for enterprises managing diverse content types across departments. Traditional methods struggle with variable formats, complex layouts, and contextual relationships within documents. The evolution from rigid rule-based systems to advanced language models marks a transformative shift in document processing capabilities. Cloud-native solutions leveraging Large Language Models (LLMs) with Retrieval-Augmented Generation (RAG) architectures offer superior performance by combining semantic understanding with precise context retrieval mechanisms. These architectures enable accurate information extraction from complex unstructured documents while maintaining enterprise-grade scalability. Implementation across domains like contract parsing and screenplay analysis demonstrates practical benefits in maintaining contextual awareness and semantic relationships that traditional methods cannot achieve. Ongoing challenges include multilingual support beyond major languages, handling degraded scanned documents, integration with existing systems, and optimizing performance in distributed environments.
