Bug paraphase mode

Hello everybody I'm using the tool in "Paraphase" mode, the functionality would be to transform a ready text into a new one by replacing some words. The input (input) receives the text, but the output does not generate a new text. And on top of that, he took it out of my credits without me having a new text. I need you to fix this, please! I'm waiting for the case Thank you very much!
