Summary
Cardinal API is a document workflow solution for developers that addresses limitations of traditional OCR and LLMs. Founded by Devi and Jianna, the technology was developed from their previous experience with Leafpress where they struggled with messy utility bill processing. Cardinal uses a fine-tuned Visual Language Model (VLM) to provide accurate, structured data with reliable bounding boxes, specifically designed for challenging documents where other tools fail.
