Frequently Asked Questions

What is Unstract?

Unstract is an open-source, no-code platform that automates the extraction and structuring of data from unstructured documents using large language models (LLMs). It enables users to create workflows that process documents into structured formats like JSON, facilitating seamless integration with data warehouses and analytics platforms.

Do I need coding experience to use Unstract?

No, Unstract is designed for non-technical users. Its intuitive, no-code interface allows you to build and deploy data extraction workflows without writing any code.

What types of documents can Unstract process?

Unstract can process a wide variety of document types, including PDFs, images, and scanned documents. It is particularly effective for documents like invoices, contracts, and forms, which may vary in format and structure.

How does Unstract ensure data privacy?

Unstract takes data privacy seriously. Documents processed through the platform are not stored during normal operations; they are discarded after processing. However, if Human-in-the-Loop (HITL) review is enabled, documents are retained temporarily for review purposes and deleted afterwards. Additionally, LLMWhisperer, the text extraction service used by Unstract, does not store documents on paid plans. On the free plan, documents may be stored and used to improve the system.

What is Prompt Studio?

Prompt Studio is a no-code environment within Unstract where users can define extraction schemas and develop prompts for data extraction. It allows for the customization of extraction logic to handle various document formats and structures effectively.

How can I deploy workflows in Unstract?

Unstract supports multiple deployment options:

API Deployments: Deploy workflows as APIs to process documents in real-time. Each API execution is independent, supporting up to 32 files per call.
ETL Pipelines: Automate the extraction, transformation, and loading of data into storage systems like Snowflake, BigQuery, or PostgreSQL.
Task Pipelines: Set up pipelines for batch processing of documents.
Human-in-the-Loop (HITL): Incorporate manual review steps into workflows to ensure data accuracy.

Can Unstract handle large documents?

Yes, Unstract is capable of processing large documents. However, for optimal performance, it's recommended to avoid chunking documents unless necessary, as chunking can impact the quality of data extraction.

What are the system requirements for running Unstract?

To run Unstract, you'll need:

LLM Service: For processing and reasoning over document content.
Embedding Model: For assigning special codes to words based on their meaning.
Vector Database: For storing and retrieving data efficiently.
Text Extractor: For extracting raw text from documents and images, including OCR capabilities.

Is there a free version of Unstract?

Yes, Unstract offers a free trial for its Cloud Edition, which includes pre-configured services like an LLM, vector database, embedding model, and LLMWhisperer for text extraction. This allows you to explore the platform's capabilities with minimal setup.
