    "Gonna be submitting our research publication and gonna have our advisor run it through a plagiarism checker, so I thought I'd do it myself as a precaution to see if my partner stole any original ideas or not. It showed good results last I checked, here's to hoping the same results appear when our advisor runs it through his own checker!"

    "This looks promising. The best thing is that it is free. If you are a teacher or professor, you often wonder if students have just copied their work. Unless you have a subscription to expensive services or want to impose onerous requirements on all students, even the innocent, it can be hard to prove anything. Dustball looks like an interesting new player. One question is whether it has access to enough sources to really be confident that it can identify plagiarism, but it is worth a shot. Even if you don't catch all the cheaters, nailing a few can be a warning to the rest."

    "Plagium charges a lot for what other options offer free of charge. I'd look elsewhere if you're looking for a plagiarism checker. This also doesn't do as great a job of finding content, which is a major problem in general but worse when it's a paid service."

    "Okay, I admit it, I've bought homework before. Yes I know, I should do the work myself, but I get crazy busy. This plagiarism checker is awesome though, because you can just copy/paste in your (or someone's...ahem) work, and BAM, it quickly identifies any problems you might have with 'borrowed' text. You know the professors are using this or something like it to make sure you're not re-using someone else's paper, so why not be ahead of the game and make sure your grade is solid!"

    "When I want to make sure my team of writers are creating their own work I sometimes don't have the time needed to back trace everything they write to make sure it's their own. For this reason I was in search of an easy to use solution that would allow me to flag all content submitted to be and spend my time focusing on that content that was flagged for plagiarism and not waste my time on content that was in no way plagiarized. When I stumbled upon Plagiarisma I knew I found the solution I was looking for. Not only would it allow me to quickly check work submissions, but it would also allow me to do individual searches within google scholar and grammar check like I normally would when making suggestions for re-writes of articles all on the same page."
