Default [Q] Making text digital in app


I am new in this fora so I hope that this post is placed in the correct discussion.

These last couple of days my mind began wondering around a certain idea for a app, but one of the main things I need in order to ever could think is possible, would be a way to digitize text from a image or scanned document for example, but to this even exist?

This is a new playing field for me, but something I wanna do, so hope that you can give me some input or point me in the right directions.
