  1. Your post was very helpful. I have used some of the plagiarism checker tools you listed above. But among all of them, I found Grammarly and Small SEO tools best. Though, Grammarly have trial subscription but its a paid tool. So, in my eyes Small SEO tool is the best free plagiarism checker. Though its checker page is crowded with many ads but I love this too much.
