Domenico Gagliardi: After you process the PDF or article, allow user to ask questions that are related to the PDF.

For example, if the PDF is related to how sugar affects the body, after scanning the PDF, Recapio allow us to enter some questions in a chat box.

Lets say, if I ask how much sugar is bad for human body. Recapio will provide response based on the content scanned from the PDF. Let say, it will response, the article mention that more than 30g a day of sugar is bad for you, and more info probably.

Hope the explaination is clear
