Sparrow is an open-source framework for structured data extraction from documents (PDFs, images) using ML, LLMs, and Vision LLMs, with schema-driven extraction and agentic workflows. It combines Vision LLM extraction with Text LLM reasoning for classification, validation, and orchestration without cloud dependencies.

Use cases

• extract structured data from invoices and receipts
• parse tables from financial reports and bank statements
• convert PDF documents to JSON with a defined schema
• classify and extract fields from multi-page documents
• build agentic document processing workflows with LLMs
• validate extracted document values against typed schemas

When to choose

• you need schema-driven structured extraction from PDFs or document images
• you want self-hosted document AI without cloud dependencies
• you need to combine vision LLM extraction with LLM reasoning and validation

When to avoid

• you need a simple turnkey OCR API with no ML setup
• your documents are plain text with no layout or tables
• you require a permissive license for proprietary redistribution (GPL-3.0)
