Document processing APIs
Parse, extract, split, classify, and edit documents through APIs designed for document-processing pipelines.
Extend
Extend is a document processing platform for turning PDFs and other documents into structured data. It helps teams parse, extract, split, classify, and route documents through APIs, Studio, Evals, Composer, and Workflows.
Overview
Extend is a document processing platform for turning PDFs and other documents into structured data. The product combines parsing, extraction, splitting, classification, editing, evaluation, and workflow tooling so teams can move from raw files to production pipelines in one system.
The site positions Extend around hard, real-world document layouts where reading order, field relationships, tables, checkboxes, and handwriting affect downstream quality. It offers API access, Studio and Evals, Composer, and Workflows, with options for cloud use or self-hosted deployment on customer infrastructure.
Core capabilities
Layout-aware OCR and parsing
Use specialized vision models and agentic OCR to handle difficult layouts, tables, checkboxes, handwriting, signatures, and bounding boxes.
Processing mode controls
Work with multiple processing modes, including low-latency, cost-optimized, and maximum-accuracy paths.
Confidence scoring and review
Run a multi-pass review agent and confidence scoring to flag uncertain outputs before they reach production.
Workflow orchestration
Orchestrate multi-step document flows with versioning, durability, human-in-the-loop steps, and routing.
Schema iteration and evaluation tools
Iterate on schemas and evaluations in Studio, while Composer helps refine schemas from examples and reduce manual prompt tuning.
Common use cases
Document extraction pipelines
Convert incoming PDFs and scans into structured fields for downstream systems, especially when document layout is inconsistent or complex.
Document splitting workflows
Break long or mixed documents into smaller units so each section can be routed, validated, or processed separately.
Structured data capture
Apply schema-driven extraction for teams that need field-level answers from forms, statements, and operational documents.
Human review and quality control
Set up review loops that score confidence, flag uncertain outputs, and catch errors before data reaches users or internal systems.
Multi-step document automation
Build end-to-end workflows that combine parsing, extraction, validation, and routing with support for durability and versioning.
