Whereas some of the spelling and grammar check rules apply to all the variants of English that's used around the globe; some rules are not universal.

It's important to remember that grammar errors can occur based on some factors and combinations. Grammar checker will not flag a previous error made by a user. For example, if a user writes 'carrots eat the rabbit' it will not be highlighted as having a grammatical mistake. If you examine the sentence, there's no grammatical error in it!
