Probably Great, If All of Your Sources Are Websites Hey, this service is probably great, if all of your sources are websites. Since you can't try out the service before sinking money into it, you will spend some to find out whether it works for you. For me, it miss-identified a basic McLuhan citation, and failed to recognize any in text citations from book sources in the Chicago Full-Note format. It even suggested, the title of an in-text citation to be plagiarism. The thing is, with a limited number of pricey tries, the amount of iterations to figure out how to get a decent result should not be put on the user! Particularly, with plagiarism testing, the tool should hopefully over-and not underreport, but by not recognizing any book publication prior to 2010, this seems like a big risk. It honestly seems like you are paying for a very baseline service, a sort of feelgood expenditure. While the support responded quickly and kindly, apparently not providing refunds is part of their business model. I am genuinely curious why this software has so many good reviews here. Edit: I just read some more reviews, and I am not sure why, but most of them are one- or two-liners from the 20th to the 30th May 2020. That is a little odd, and maybe presents something for Trustpilot to look into.

Reliable plagiarism checker I am a freelance copywriter and have to check tons of papers every month. I love Unplag's feature to scan for similarities unlim # of papers in a background mode while the checking speed remains 4-10 sec. Highly recommend.

Waste of money Waste of money. Doesn't detect anything. Of course they don't tell you they only check against open access sources in advance. No refund either for doing nothing.

If you like using Bing, you'll love Unicheck. Otherwise... Bunch of things. For starters, with a Personal account you can't do Side-by-Side comparisons. Fine, fair enough. But then when I took a close look at the report turns out it missed over 50% of the items that were copied directly from a wide variety of business news sites. For each of them, pasting the text into Google brought up the page in the first result. When I enquired with customer support, the explanation was: "Our system uses Bing search engine, unfortunately some texts are indexed in the Google only". Um, ok. Yeah. I think that pretty much says it all. When I asked about a refund I was told: "Our service is non-refundable. It’s stated in our customer agreement which you had opportunity to read and agreed while creating an account." Guess I missed the part about their reliance on the Bing search engine. Use at your own risk. UPDATE: After saying goodbye to my $10, I tried the same doc again on Scribbr. Yes, it cost $20. That's why I went with Unicheck in the first place. But let's just say you get what you paid for. Scribber found at least 2x as many items that were copied from websites. Also, I went for it because, unlike Unicheck, they had a 100% Happiness Refund guarantee. So there you go. Good luck.

One of the worst plagiarism checkers One of the worst plagiarism checkers. First off, they are so expensive. They call it as free but when you try to use it, it doesn't show anything. Secondly it would even show references as plagiarized. How is it possible?
