Cardinal
Build your document workflow with one API
About
Cardinal is a next-generation document processing API designed to go beyond traditional OCR, enabling users to build and run entire document workflows. It specializes in splitting, extracting, and structuring messy, real-world documents across various industries such as healthcare, accounting, supply chain, and finance. Key features include natural-language page classification (Split), custom schema extraction (Extract), clean Markdown text output, and intelligent chunking for RAG workflows with bounding boxes. The platform supports a wide range of document formats, including faxed forms, scanned documents, complex tables, and offers multilingual support for over 100 languages. Cardinal emphasizes enterprise-grade security, being HIPAA and SOC2 compliant, offering BAA's, zero data retention, and end-to-end encryption. Founded by Devi and Jianna, who developed Cardinal out of their own frustrations with existing document processing solutions while building their previous company, Leafpress.
