Queues Queues too long for a paid service, sometimes can go up to an hour which is horrid compared to other paid and even free plagiarism-checkers. Also doesnt accept direct credit card payments, only PayPal. Helpful and fast support team, though.

The software was used by my university The software was used by my university, and claimed that I had plagiarized 31% of a paper. I wrote my paper from scratch, and even demonstrated to my teacher where I found my information and how it was dissimilar from the wording of my paper. This is the only plagiarism checker that checks against the web and gave a false positive on the same paper. It claims to be free for students but it isn't unless your teacher sets up an account for you. As more papers get put into their system and online there is a greater and greater chance that it will falsely accuse of plagiarism.

I won't recommend this checker This plagiarism checker is not efficient, at least for me. Because why will it rate my assignment with a 1% similarity score and then my school runs it on turnitin and it churns up 35% based on comparison with internet sources. Unicheck just isn't doing well.

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.

Great plagiarism checker! Great plagiarism checker! I have been using the free version of Unicheck for about 4 months and have loved how accurate it has been. You get to check 500 words each time and I think 4-5 times before it cuts you off and offers you to upgrade. You can choose to purchase one of their options or wait 2 - 3 hours before you can use the free version again. I just saw that there is an option to buy the individual version and you can choose the amount of pages you will actually use. The first option is 20 pages for $5 which isn't too bad. I'm thinking about how many pages I actually want to buy. I think 100 pages for $15 is a great deal so I think that'll be the one I go with.
