When Extend is the better choice

Document intelligence solutions require tooling beyond parsing accuracy. Unstructured data represents an estimated 80-90% of all new enterprise data and is growing 3x faster than structured data. Building the infrastructure to maintain and analyze this data yourself means months of development time and ongoing maintenance overhead.

Extend is the complete document processing toolkit comprised of the most accurate parsing, extraction, and splitting APIs to ship your hardest use cases in minutes, not months. In addition to best-in-class parsing, Extend offers a suite of models, infrastructure, and tooling for the most powerful custom document solution, without any of the overhead. Agents automate the entire lifecycle of document processing, allowing your engineering teams to process your most complex documents and optimize performance at scale

Companies like Brex, Mercury, Zillow, Amgen, First American, and hundreds of others chose Extend after testing every alternative because Extend delivered superior real-world performance with the surrounding infrastructure their teams actually needed. If you're building RAG systems or automation workflows, you need both exceptional accuracy and the tooling to maintain it at scale.

When Reducto may fit

Reducto's focused parsing API works well if you have simpler use cases that don’t require extreme accuracy. But most teams don't. They need classification, splitting, confidence scoring, human review tools, and automated optimization to reach production quality.

For teams that don’t need very high accuracy on end-to-end document pipelines and just need a simple parsing API, Reducto's focused approach can work. But if you're looking for an end-to-end solution that enables extreme accuracy for the most demanding pipelines, you'll need to assess whether a sole parsing-focused tool meets your requirements.

Final thoughts on choosing a document intelligence systems

Choosing between document AI platforms depends on how much infrastructure you want to build and maintain yourself. Reducto delivers capable parsing but leaves teams responsible for the rest of the workflow: classification, optimization, validation, and continuous improvement. Extend provides it all in one integrated system that learns from every correction your team makes, achieving up to 99% accuracy in minutes and improving automatically as document volume grows. It’s the complete foundation for long-term document intelligence at scale.

FAQ

What's the main difference between Reducto and Extend for document processing?

Reducto focuses on parsing accuracy with upload, parse, split, extract, and edit capabilities, while Extend is the complete document processing toolkit comprised of the most accurate parsing, extraction, and splitting APIs with built-in classification, workflow automation, human-in-the-loop review, and the Composer AI agent that automatically optimizes extraction schemas to achieve 99%+ accuracy in minutes.

How quickly can I achieve production-level accuracy with document extraction?

Extend's Composer AI agent runs parallel evaluations and continuous learning to reach 99%+ accuracy in minutes instead of the weeks or months required for manual tuning. Documented case studies show Brex achieved 99.13% accuracy and HomeLight jumped from ~85% to 99%+ accuracy with manual review turned off entirely.

When should I choose a parsing-only tool versus an end-to-end solution?

Choose a parsing-only tool like Reducto if you have simpler use cases that don’t require extreme accuracy enabled by classification, splitting, confidence scoring, human review tools, and optimization infrastructure in place. Choose Extend if you need the full document processing lifecycle in one system that learns from corrections and improves automatically as document volume grows.

Can I deploy document processing infrastructure in my own environment?

Yes, Extend supports cloud, VPC, and on-premises deployment options with Bring Your Own Cloud (BYOC) for customers with heightened security or data-residency requirements. All foundation-model providers operate under strict zero-data-retention terms, and Extend is SOC2, HIPAA, and GDPR compliant.

How does automated optimization work for complex document types?

Extend's Composer AI agent learns from your documents and iteratively tweaks processing logic by experimenting with prompt changes and running evaluations in parallel. The built-in Memory system remembers and uses validated historical results to improve performance on new documents, creating a self-improving system that gets better with every correction your team makes.
