Part II - Best Free Plagiarism Checker
Veering away from the subject of grammar, let's head on to a more controversial topic: Plagiarism. This is a completely different animal. There are some ignorant individuals out there who think that it's OK to copy somebody else's work and pass it off as their own. Little do they know that what they are doing is considered a crime and they can get severe penalties for it. Fortunately, there are many websites which can help a person search for plagiarized copies of their work. One such plagiarism checker is found in Dustball.com and it has already helped a lot of people catch these nasty plagiarists.
This plagiarism checker is really easy to use. You just need to copy and paste your work in the provided text box, and it will scour the web for potential plagiarized copies of your work. Some plagiarists think that they can circumvent the plagiarism checking system by only copying some parts of an article. This is not a problem for Dustball's Plagiarism Checker because it actually separates your work into sections and then compares each of these sections with whole documents. Even the craftiest plagiarist who takes snippets from different sources and then pastes them together to form a single article can't fool this plagiarism checker!
If you still find yourself struggling with grammar or plagiarism issues, feel free to use these checkers as much as you can. Indeed, these are two of the most helpful online tools for a writer who takes his or her craft seriously.
