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.

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.

Good instrument for plagiarism… Good instrument for plagiarism checking! Using it in daily work) Sometimes it is quite laggy, but support is great and solves all issues as fast as possible! Recommend!

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.

Unsatisfactory business practices Unsatisfactory business practices. They impose a time limit on the pages you buy, which reflects poorly on their customer service. Once you've utilised the service, the cost seems inconsequential to them. It feels as if they've taken my money without fair value in return.
