This extension will check your spelling and grammar in real time as you type. This way you will make sure that important emails you send are well written, so are Facebook statuses or messages, twitter tweets on your blog at Steemit and almost everywhere actually. ). In the next step to check the effectiveness of the plugin, you need to interpret your e-mail, and the next message you send will appear in the icon of the extension. Words that are not written correctly will be highlighted in red, and there will also be an icon that shows the number of your mistakes and offers more appropriate alternatives.
By the way, as you can see in the picture, Grammarly does not check email errors, which is quite problematic since it is known that the first impression is everything. But - of course, you can copy the text to the body of the email to make sure everything is normal.
