Using a free online spell checker usually involves typing or pasting text into a box on the page and then clicking a button to initiate the spell check. Depending on the website, spelling errors may be highlighted in the text box or featured in a pop-up window, and there will be suggestions shown for correcting the error. Reverso, Spellex and SpellBoy are three free options.
Reverso lets users check the spelling of text in various languages, and it offers additional help with grammar. Spellex only checks for spelling issues but can handle special formatting. SpellBoy is a spell checker with additional options for saving text and viewing statistics, such as word and character counts.
