I used the website www.writecheck.com, but I highly advise not to use the website. But I signed up and no one told me that the resubmission must be at least 70% similar to the original document. No one told me that there was such rule. Also, I noticed that they took small charges and it wasn’t for subscription. I wasn’t glad that I have registered on the website. So, I don’t recommend anyone use it.
Not worth the money for legal papers. It doesn't recognize standard phrases, can't seem to understand when things are properly referenced (it even treats the references as plagiarized!); overall hopeless.
