Rossum AI Engines

An AI engine is designed to extract and predict data from your documents.

Generic Engines

Generic Engines are ready-to-use, pre-built engines available to our customers right away. There are different versions of Generic Engines to choose from. Engines listed below are legacy solutions that we continue to maintain and support for our existing customers who use them.

AP & AR Generic Engine

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.

Aurora Instant Learning

This engine is not pre-trained on any specific data. It quickly learns to recognise custom data using user annotations and is recommended for custom use cases.

Dedicated Engines

Dedicated engines are designed for a specific use case and are trained using documents and annotations from a particular customer. Our team regularly re-trains these engines to keep them updated. Unlike Aurora, dedicated engines do not offer instant learning; training results are only visible after our team completes the re-training process, not after just a few annotations. Dedicated Engines are legacy solutions that we continue to maintain and support for our existing customers who use them.
