Extend Operational

Extend is a developer platform for processing unstructured documents. Users can upload and process files through the API, CLI, or Studio to perform layout parsing, structured field extraction, multi-document splitting, classification, and form editing. They can also configure workflows, run evaluations, and inspect output quality. The platform supports multiple file types and languages, and provides Python, TypeScript, Java, and Go SDKs.

AI application development teams

Turn complex files such as PDFs into context that agents can use, and integrate it with existing AI applications or data pipelines.

Data and machine learning engineers

Build document parsing, field extraction, classification, and splitting workflows with APIs, SDKs, and the CLI, and test them during development.

Enterprise domain experts and product teams

Adjust extraction schemas in Studio, run evaluations, and identify regressions while contributing to the iteration of document processing solutions.

Companies in regulated industries

Process sensitive documents in healthcare, finance, real estate, supply chain, and other sectors, selecting compliance and deployment capabilities based on their enterprise requirements.

Document parsing

Parse unstructured documents into context for agents and pipelines, identifying layout elements such as tables, checkboxes, images, handwriting, and signatures.

Structured information extraction

Extract structured data from documents according to user-defined schemas, making it suitable for converting contracts, forms, and other files into fields that applications can process.

Multi-document splitting

Identify bundled documents containing multiple files and split them into independent subdocuments for separate parsing, extraction, or routing.

Document classification

Classify documents according to predefined categories, serving as an identification and routing step in document processing workflows.

Form editing

Detect form fields in documents and populate them programmatically for file processing tasks that require field recognition and content entry.

Workflow orchestration

Combine parsing, splitting, extraction, validation, and routing steps to create multi-step document workflows with version management and persistence.

Studio and evaluations

Iterate on schemas in a visual interface, run evaluation sets, and inspect regressions to help teams validate document processing results before release.

Composer and review

After examples are uploaded, Composer identifies issues and optimizes schemas; review agents can perform multiple rounds of output checks and flag potential errors.

Parsing for complex layouts

Layout models cover tables, checkboxes, images, handwriting, and signatures, combining computer vision and vision-language models to process page elements.

Unified document processing APIs

Parse, Extract, Split, Classify, and Edit capabilities are provided through one platform, covering the major stages from content parsing through downstream processing.

Development-to-production toolchain

In addition to APIs and SDKs, Extend provides Studio, evaluations, Composer, review agents, and workflow version management to support continuous iteration of processing solutions.

Multiple performance modes

Switch between processing modes optimized for low latency, cost efficiency, or high accuracy to support different scenarios, including real-time and batch tasks.

Enterprise deployment and data controls

Enterprise plans support self-hosted deployment, SSO and SAML, RBAC, custom models, and data retention settings, along with zero data retention.
