What does Extend do?

Extend is a document processing platform that converts unstructured documents into structured data for AI agents and applications. It handles complex document types including financial statements, legal contracts, and healthcare records, transforming them into usable formats that AI systems can understand and process. The platform specializes in maintaining document structure and context, which is essential for accurate AI analysis.

The system provides multiple API endpoints for different document processing tasks: parsing converts documents into agent-readable context, extraction pulls specific data into custom schemas, splitting separates multi-document files, classification categorizes documents automatically, and form editing detects and fills form fields. Extend includes features like confidence scoring to flag uncertain results, multiple processing modes for different use cases, and workflow orchestration for complex document pipelines. It processes millions of pages daily and handles documents up to 1,000+ pages with precise bounding boxes for citations.

Extend serves AI teams at companies like Brex, Vendr, and Checkr who need reliable document processing for their AI applications. It's particularly valuable for financial services, real estate, logistics, and healthcare companies that work with complex document formats and require high accuracy for production AI systems. The platform eliminates the need for teams to build and maintain their own document processing infrastructure.
