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.

Current State vs. Unstract

Task	Without Unstract	With Unstract

New document type	Days of development	Minutes in Prompt Studio
LLM integration	Build your own pipeline	Plug in any provider (OpenAI, Anthropic, Bedrock, Ollama)
Deployment	Custom infrastructure	`./run-platform.sh` or managed cloud
Output	Unstructured text blobs	Clean JSON, ready for your database
