Grammarly
Checks grammar, clarity and tone as you type in emails, documents and web forms, and helps draft and edit text on most sites.
Chrome extension
Checks writing for grammar, spelling and style mistakes in many languages, with one-click fixes and a right-click check on any page.
Grammar Checker finds grammar, spelling and style mistakes in text you write and lets you apply suggested fixes with a click. It is useful for anyone writing in one of its many supported languages who wants checks beyond a basic spell checker.
Click the toolbar icon and paste or type text into the checker, or select text on a page, right-click and choose to check grammar.
Checking is powered by the LanguageTool API, so your text is sent to that service. Text is saved between visits unless you clear the text area.
