What it does

Unstract extracts structured data from unstructured sources like documents and text using large language models, making it easier to integrate into API deployments and ETL pipeline workflows.

When to use it
  • You need to automate data extraction from invoices, receipts, or contracts.
  • Your startup relies on manual data entry from unstructured text data.
  • You're building an ETL pipeline that requires extracting specific data points from large documents.
Ready-to-paste prompt
python examples/extractor.py --input example.pdf --output extracted_data.json --config config.json
Heads up: Make sure you have the necessary large language model dependencies installed and configured, as unstract relies on these models for data extraction.
