Extend

Extend is document processing infrastructure for AI agents. It parses, extracts, splits, verifies, and edits documents, aimed at engineering teams in healthcare, real estate, insurance, and finance that need to turn unstructured documents into usable data. Extend reports 95.7% accuracy on its RealDoc-Bench parsing benchmark.

A developer calls Extend's Parse, Extract, Classify, Split, or Edit APIs through SDKs in Python, TypeScript, Java, or Go, or through the CLI, or builds and tests pipelines first in a browser-based Studio before copying the API call into code. Extend's Composer Agent refines extraction schemas automatically from uploaded examples, and a Review Agent checks every output and flags potential errors before they reach users.

Extend offers a Fast mode to switch between low-latency, cost-optimized, or maximum-accuracy processing per document, and document workflows that chain parsing, splitting, extraction, validation, and routing with versioning built in. A Verify API detects tampered, forged, or AI-generated documents, and deployment options include Extend's US or EU cloud, a customer's own VPC, or keeping documents in the customer's cloud while Extend runs inference. Extend is SOC 2, HIPAA, and GDPR certified.

Extend's Pay As You Go plan is free to start with 10,000 credits, worth $100, then charges $0.01 per additional credit with no contract or monthly minimum; it is capped at 60 concurrent documents and 500 concurrent pages. Growth adds custom credit volume, higher rate limits, and HIPAA compliance for teams scaling document volume, and Enterprise adds BYOC or hybrid deployment, SSO, and custom rate limits, both priced on request.

Use cases

• Turning documents into clean markdown or blocks for RAG and agents
• Pulling specific fields into structured JSON from invoices, IDs or contracts
• Routing incoming documents to the right downstream process
• Splitting a multi-document PDF into separate files by type
• Detecting tampered, forged or AI-generated documents before trusting them
