"I work online a lot, so when browsers get heavy and slow it really annoys me because everything takes longer. In my experience, Brave is good for this because it normally loads everything faster! And the fact that they claim to be private and not track what you do is definitely a plus!"

    "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."
