What is Extend?
Extend is a full-stack document processing cloud that turns messy PDFs, emails, images, and other unstructured files into production-ready structured data. It combines state-of-the-art LLMs and specialized vision models with a batteries-included toolkit (Parse, Extract, Classify, Split, Edit APIs, Studio, Composer, Review Agent, and Workflows) so teams can go from raw documents to reliable pipelines in days instead of months.
The platform is designed for technical teams building document agents, AI workflows, and data pipelines in finance, healthcare, logistics, insurance, real estate, and other industries where documents are the system of record. Extend provides layout-first parsing (Parse 2.0), confidence scoring, multiple processing modes (fast/low-latency vs accuracy-optimized), agentic OCR, multi-step workflow orchestration, and evaluation tools, all with SOC 2, HIPAA, and GDPR compliance.
Extend is used by AI-forward startups and F500s (Brex, Vendr, Flatiron Health, Square, Zillow, Chime, and others) to eliminate entire classes of engineering problems around document accuracy, reading order, table extraction, and schema generation. It supports 25+ file types, 2,000+ page documents, advanced table and array extraction, signature and checkbox detection, and offers self-hosted deployments, custom models, and enterprise-grade security for regulated industries.
Key features include: Parse 2.0 layout-first API, Extract API with schema generation and citations, Classify API with memory, Split API for large documents, Edit API for agent form filling, Composer Agent for automatic schema optimization, Review Agent for multi-pass error checking, Studio & Evals for no-code iteration, and Workflows for durable, versioned pipelines. The platform also offers agentic OCR, bounding boxes, multiple chunking strategies, low-latency mode, and webhook integrations.
Extend pricing
Pricing model: Free
Extend uses a credit-based pricing model where each API (Parse, Extract, Classify, Split, Edit) consumes a fixed number of credits per page. There are three main tiers: Pay As You Go includes 10,000 free credits and full product access (Parse, Extract, Classify, Split, Edit APIs, Studio, Composer, Review Agent, Agentic OCR, Workflows); Scale is $500/month and includes 50,000 credits/month plus private Slack support, volume discounts, higher rate limits, custom data retention, and HIPAA/BAA add-on; Enterprise is custom-priced and adds self-hosted deployments, custom MSA/DPA/SLAs, SSO/SAML, advanced RBAC, multiple workspaces, custom models, custom rate limits, and dedicated support. Higher-tier plans have lower per-credit rates, so cost per page decreases as you scale. Users can view real-time credit usage, set low-balance alerts, and configure automatic top-ups in Settings > Billing.

Extend cons
- No public flat pricing; credit-based model can be opaque
- Requires API key and developer setup for most features
- Self-hosted and custom models only on Enterprise tier
- HIPAA BAA is an add-on on Scale, not default
- Higher-tier features (Slack support, volume discounts) require paid plans
- Credit usage monitoring and alerts must be configured manually
- Some advanced capabilities assume technical/AI team expertise
- Rate limits are limited on Pay As You Go plan
- Custom data retention only available on Scale/Enterprise
- Documentation is developer-heavy; less guidance for non-technical users
Frequently asked questions about Extend
What is Extend and what does it do?
Extend is a full-stack document processing cloud that parses, extracts, classifies, splits, and edits documents (PDFs, images, emails, etc.) into high-quality structured data. It combines state-of-the-art LLMs and specialized vision models with tooling like Composer, Review Agent, Studio, and Workflows so teams can build reliable document agents and data pipelines in minutes instead of months.
How do credits work in Extend?
Credits are Extend's universal billing unit. Each API (Parse, Extract, Split, Classify, or Edit) consumes a fixed number of credits per page. Your cost per page is credits per page × your plan's per-credit rate. Higher-tier plans have lower per-credit rates, so cost per page drops as you scale.
What plans does Extend offer?
Extend offers Pay As You Go (10,000 free credits, full product access, pay as you go thereafter), Scale ($500/month with 50,000 credits/month, Slack support, volume discounts, higher rate limits, custom data retention, HIPAA/BAA add-on), and Enterprise (custom pricing with self-hosted deployments, custom contracts, SSO/SAML, advanced RBAC, multiple workspaces, custom models, dedicated support).
Does Extend support self-hosted deployment?
Yes. Extend offers self-hosted deployments for organizations that need to keep sensitive documents on their own infrastructure. This is available on the Enterprise tier and provides the same speed, accuracy, and features as the cloud version.
Is Extend compliant with healthcare and regulated industries?
Extend is built for regulated industries and is SOC 2, HIPAA, and GDPR compliant. A Business Associate Agreement (BAA) is available as an add-on on the Scale plan and is included on Enterprise. The platform also supports custom data retention agreements and advanced security features.
What document types and sizes does Extend support?
Extend supports 25+ file types and documents up to 2,000+ pages. It handles complex layouts, multi-page tables, signatures, checkboxes, handwriting, images, and advanced array extractions. The platform includes agentic OCR, bounding boxes, and multiple chunking strategies for difficult documents.
How does Extend's accuracy compare to other solutions?
On RealDoc-Bench, which tests production documents where layout, reading order, and field relationships matter, Extend Parse 2.0 achieves 95.7% accuracy, outperforming Extend Parse 1.0 (90.4%), Gemini 3.5 Flash (89.04%), Azure DI (88.8%), and AWS Textract (70.5%). Customer stories from Brex, Vendr, and Flatiron Health confirm it outperforms other vendors, open source, and foundation models.
What is Composer Agent and how does it help?
Composer Agent is an optimization agent that removes manual prompt and schema trial-and-error. You upload examples and Composer automatically identifies issues, refines your schemas, and improves accuracy in the background. This speeds up iteration and reduces engineering time spent tuning document pipelines.
How do Workflows and Studio fit into Extend?
Workflows provide end-to-end orchestration for complex pipelines: parse, split, extract, validate, and route documents with versioning and durability out of the box. Studio & Evals give domain experts an intuitive interface to iterate on schemas, run evaluations, catch regressions, and ship with confidence without writing CLI scripts.
Can I get support and custom contracts with Extend?
Yes. Pay As You Go users get chat support; Scale users get a private Slack channel and volume discounts; Enterprise users get dedicated support, custom MSA/DPA/SLAs, SSO/SAML, advanced RBAC, multiple workspaces, custom models, and custom rate limits. Higher-tier plans also offer custom data retention agreements and deployment engineering support.
