Can I extract a specific field?

Absolutely! Koncile’s OCR extraction service offers fully customizable fields. Our pre-built models are just a starting point—you can modify and add your own fields to meet your specific needs.

How does Koncile integrate with my existing tools and software?

Koncile is accessible via a powerful API, with full documentation available here. Additionally, you can upload documents directly in the app and download extracted data in XLSX, XLS, CSV or JSON formats for seamless integration into your workflows.

I need to parse a document that’s very specific to my industry. 
Can Koncile handle it?

Of course! Start by exploring our library of pre-built templates, covering a wide range of industries. If you don’t find one that fits your needs, you can easily create your own custom model.

What are “General Fields” and “Repeated Fields”?

In each extraction template, you’ll find:

General fields: These are pieces of information that appear only once per document (e.g., an invoice number or date).

Repeated fields: These are elements that appear multiple times within a document, such as item descriptions or prices in each line of a quote. Use repeated fields to extract tables and structured data from your documents.

What file formats does Koncile support?

Koncile allows you to import PDF files and all common image formats, including PNG and JPEG.

What is Koncile’s pricing structure?

Koncile offers three plans, including enterprise options for handling large data volumes. Check out our pricing on the dedicated page in our documentation.
