GrammarCheck, when compared to the other tools out there, looks bare bones and lacking in features. However, its ease of use is a selling point. There are no downloads required to utilize its reliable software, just paste in your text and quickly get a report on it.


Hemmingway is an impressive little app that can not only flag simple mistakes but also rates you on the clarity of your text and scores your writing skills. The more accessible the program rates you, the easier your writing will be understood. There are two different version of Hemmingway – a free version and a paid version ( for $10). Note that Hemmingway’s main function isn’t checking for grammar, like other apps listed here, but it is valuable for copyediting and catching the occasional error.

SpellCheckPlus isn’t the best grammar checking device out there, but it was designed to be of service for non-native speakers of English. If English isn’t your primary language, the tool could be helpful. SpellCheckPlus seems to use a different error checking algorithm than some of the other tools out there and as a result, it seems to flag different things as errors. SpellCheckPlus’ developers offer a free version of their program, though its limitations include the fact that it will only flag errors and not explain why it was an error. If you want these features you’ll need to upgrade to the Pro account which costs $15.


What makes PaperRater a very popular grammar checking tool is that it can also do plagiarism checking. It’s a free, online-based tool, so you won’t have to install anything to use it. PaperRater claims that it has over 10 billion different, stored text documents that it checks against for plagiarism, which is why many students, bloggers, and freelance writers use it. The tool will even find similar writing that other writers have published on their own websites, outside of the documents on their servers.
