Quickstart

A streamlined document processing library that leverages AI vision models for OCR and data extraction. Designed to handle complex document layouts including tables, charts, and irregular formatting.

• Universal Document Support: Process PDFs, DOCX, images, and more

• Vision-Based Processing: Uses AI vision models for superior layout understanding

• Structured Output: Converts documents to clean Markdown or extracts specific data

• Multi-Platform: Available for both Node.js and Python

How It Works

1. Upload any supported document

2. Document is automatically converted into a series of images

3. Vision models process each page

4. Returns clean, structured output in Markdown or extracted data
