Unstract

Turn Unstructured Documents into Structured Data

Documentation | Enterprise

What is Unstract?

Unstract uses LLMs to extract structured JSON from documents — PDFs, images, scans, you name it. Define what you want to extract using natural language prompts, and deploy as an API or ETL pipeline.

Built for teams in finance, insurance, healthcare, KYC/compliance, and much more.
