Dex is Scale’s document understanding service that transforms unstructured documents into actionable, structured data. It is a comprehensive platform that combines advanced OCR, natural language processing, and machine learning to extract meaningful information from PDFs, images, spreadsheets, and more.

Why Use Dex?

Dex solves the most common challenges of programmatic document processing:
  • Format Diversity: Process any document type with a single API.

  • Quality Variations: Handle scanned, handwritten, and low-quality documents with high accuracy.
  • Scalability: Process thousands of documents efficiently with a built-in scalable infrastructure.

Key Capabilities

Document Parsing

Transform any document into a consistent, structured format. Dex organizes content into semantic blocks (e.g., titles, paragraphs) with precise bounding boxes and optimizes it for search and retrieval.

Data Extraction

Extract specific information using custom schemas and prompts. Define your data needs with Pydantic models and guide the process with natural language instructions. You can also choose from various language models for different use cases.

Project Management

Organize and secure your workflows. Each project isolates data and credentials, providing a full audit trail for compliance and debugging.

Common Use Cases

  • Financial Services: Automate invoice processing and tax document analysis.
  • Healthcare: Extract patient information from medical records and insurance claims.
  • Legal: Analyze contracts and large volumes of discovery documents.
  • Business Operations: Process HR documents, supply chain orders, and customer service tickets.

Getting Started

To begin using Dex, you’ll need a Scale account. Once you’re set up, you can easily install the SDK, create a project, and start extracting data. Dex makes document understanding accessible to developers while delivering the power and accuracy required for production applications.
