Hello,

I want to learn that what kind of programs can we use to check plagiarism or similarity? Can we check that? If yes, how reliable is that? After using the programs to check or websites (I do not have any idea if there is any program or website, can I be relaxed? Is there anyone have any idea?

I read some kind of issues about websites saving the text. That's why I asked, thank you. These are reliable websites I believe...
