unstract

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 | |------|------------------|---------------| | Schema definition | Write regex, build templates per vendor | Write a prompt once, handles variations | | 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 |
