Unstract is an open-source, LLM-driven platform that extracts structured JSON data from unstructured documents such as PDFs, images, and scans using natural-language prompts. It supports deployment as APIs, ETL pipelines, and an MCP server, with features like dual-LLM validation (LLMChallenge) and token-saving extraction modes.

Use cases

  • extract structured data from pdfs with llm
  • parse invoices into json automatically
  • build an etl pipeline for unstructured documents
  • deploy document extraction as an api
  • process bank statements without templates
  • add document extraction to ai agents via mcp
  • reduce llm token costs for document parsing
  • automate accounts payable document processing

When to choose

  • you need production-grade extraction from varied document formats without training or templates
  • you want API or ETL deployment of document extraction workflows
  • hallucination control matters - dual-LLM consensus validation is valuable
  • you need connectors to file systems and databases for bulk document processing

When to avoid

  • you only need simple OCR text extraction without structured output
  • you want a lightweight library to embed in code rather than a platform to deploy
  • AGPL-3.0 licensing is incompatible with your usage
  • your documents are already structured (CSV, JSON) and need no LLM parsing
