Human in the Loop

Human in the Loop

As an AI platform inSTREAM requires human interaction to learn.  Through an easy to use Graphical User Interface (GUI) inSTREAM collaborates with the AP team or who teach it where to find key information. inSTREAM learns from every document it processes, therefore as the volume of invoices processed increases, its confidence and accuracy improve and the amount of interaction needed with humans decreases, enabling employees to focus on the complex, value-based tasks.
