About Grammar Check

A free grammar checker that runs entirely in your browser, so nothing you write is ever uploaded. Paste or type and mistakes are underlined as you go: spelling in red, grammar in orange, punctuation in purple and style in blue. Tap an underline to see what's wrong in plain words and fix it in one tap, ignore it, or add the word to your own dictionary. It catches the mistakes people really make: their and there, its and it's, should of, a and an, doubled words, missing capitals and commas. American, British, Australian, Canadian or Indian English. Your documents are kept on this device. Checked by Harper, an open-source grammar checker.
