This engine is specifically designed to extract information from financial documents, mainly for Accounts Payable (AP) and Accounts Receivable (AR) tasks. It comes pre-trained to recognise a set list of fields.

While the engine doesn’t learn directly from your specific documents or annotations, it uses additional prediction methods to improve its accuracy. These fine-tuning improvements only apply to documents with very similar layouts.
