AI Document Extraction tools use machine learning and optical character recognition (OCR) to automatically pull structured data from unstructured documents like PDFs, images, and emails. By integrating LLMs, these tools can understand the context of the information they are extracting, allowing them to handle complex layouts and varied formats with high accuracy. For example, they can extract invoice details, customer information from contracts, or key findings from research papers, eliminating manual data entry and accelerating data-driven workflows.
