A CAPTCHA (/kæp.tʃə/, a contrived acronym for Completely Automated Public Turing test to tell Computers and Humans Apart) is a type of challenge–response test used in computing to determine whether or not the user is human. (Extract from the Wikipedia article on Captcha) The test is often used to check by whom entries have been made in Internet forms, since robots are often misused here.

Captchat is a made up messaging app. It offers the possibility, with the help of image manipulation, to alienate messages in such a way that they can no longer be read by robots. Instead of easily readable texts the app only sends captchas.
