Sending emails to customers was a challenge for me and Quillbot was one of the best discoveries ever I had. - Rephrasing your sentences and emails in a fluent and professional manner was an enormous advantage and a massive headstart for me among my coworkers, as it was rephrasing and correcting my email grammatically and structurally. - What I enjoy best about it is how simple it is to use. With one click, it will recreate anything you want and offer you the choice of choosing between sentences and words if you don't like the way it was rewritten. -all of the above is just one tool or feature in the Quillbot and it has more to be put in use but mine one is the paraphrase and the grammar checkers. - Best free App and extension to be but in customer service use.
