Extend provides a suite of document processing APIs that parse, extract, split, classify, and edit unstructured documents with high accuracy. The platform uses a hybrid computer vision and vision language model pipeline to handle complex layouts, tables, checkboxes, handwriting, and signatures. It supports 25 file types, 100+ languages, and offers multiple performance modes (speed, cost, accuracy). Extend also includes a Composer Agent for automatic schema optimization, document workflows for multi step pipelines, and a Studio & Evals interface for iteration and regression testing.
