# Azure PDF Expert - Standalone

The AzurePDFExpert is a conversational question answering expert. This expert also demonstrates the ability to attach the behavior of an expert to an external knowledge source/API. Answers to free form questions are generated using the Microsoft Azure PDF QnA system which is able to digest information in a PDF file (such as a user manual) and allows question answering based on the contents on the PDF. When a relevant response is generated from the external system, this expert allows SCAI to present that response to the user.
