Question

Work organization

Hello!
I decided to defeat the following automation:
a picture of the cover of a book was taken on the iPhone the
photo was moved to the "Books" album - this starts the process of the applet's work the
text from the cover is recognized or a search is performed by the image
the result is checked on the sites litres, myth, alpina
a card is created in trello with search results .
