Text reading bot?

Question

How to make a bot that takes a screenshot every 5s and then searches for a text,now when it finds text i want it to pick the most bottom one left(bcs on the right is my text),then make that text a variable,and then compare it to some variable(like string x = "listofcomm")and if matched then send a text corresponding to it?example
x = text from image;
y = "router password"
String ytext = "Password is 1234432100"
If (x == y) {
sendText(ytext);
}
