It shows plagiarism 0% but similarity is about 27% does similarity cause issues for publishing or similarity doesn’t create any issue? ---

I have access to Turnitin because of my old school. If you feel comfortable enough to share your paper to me here publicly, I’ll screenshot your similarity score. If not I get it, but I’ve been where you are and I just wanna help if I can. ---

MOSS/JPlag are the same core tech, free, no cap. **The one thing to know:** a similarity score is a guide, not a verdict. If it flags something, the fix is a proper citation — not shuffling words around. Cite as you write and the score handles itself. _Free didn’t mean worse. It just meant nobody told you where the real tools were kept._
