Try this extension if you need to proofread your posts, text, emails
Grammarly is a Google Chrome extension that checks English text for spelling, punctuation, readability, and more.
The service has an application for Windows, Microsoft Office and keyboard for Android and iOS as well.
In the settings, you can choose the type of English: American, Canadian or Australian.
Grammarly works with any text box. Extension icon appears with the number of errors. When you click on it, an editor opens, in which all errors are highlighted.
For each error, Grammarly proposes correction, as well as a rule that describes why the error should be fixed. To apply suggestion you need to click on it.
Grammarly has a paid version. It adds a readability check, improved vocabulary, plagiarism checks and hints for specific text genres.
The free version is enough for most users. I recommend bloggers and authors to buy the paid version.
