Does rewriting my essay with a rephrasing tool count as plagiarism?

Yes, using a rephrasing tool this way can definitely count as plagiarism, and it is highly likely to trigger academic integrity flags. I completely understand how stressful this is for you. Studying in a second language is incredibly tough, and it is totally natural that you wanted some help to make your grammar shine. You are trying your best to cite your sources, which is great, but these online tools often just swap words out with synonyms while keeping the exact blueprint of the original text. Think of it like taking someone else’s house, painting the front door a different color, and claiming you built the whole structure from scratch. Professors and detection software can easily spot that the underlying skeleton of the writing isn't actually yours. To fix this and ease your mind, I highly recommend taking a step back from the rewriter. Since you already have the ideas cited, try explaining those sociology concepts out loud in your own words, as if you were explaining them to a friend over coffee. Write down exactly what you say, even if the grammar feels a bit messy or imperfect. Your professors actually want to hear your unique voice, and they are usually much more forgiving of a few minor grammar slips than they are of automated, robotic phrasing. You can also take your rough draft to your campus writing center, where real human tutors can help you polish your English without risking your academic standing. You've got the drive to do this right, so trust in your own voice and give yourself the chance to write this honestly.
