In the recent update, Grammarly added the new tone detector feature which makes sure that you have the tone of your message correctly.
For instance, if you want to send an email you can keep the tone as “formal”. For a social media post, you can keep it an “informal” tone.
This is what I received in my email box from the official team of Grammarly;
Grammarly Tone Detector
Grammarly states that with the help of machine learning and some advanced set of rules the algorithm is able to find a pattern of words and can detect the tone effectively.
Currently, Grammarly detects over 40 different tones ranging from "formal", "informal", "sad", "curious", "surprised" etc.
You’ll start getting automatic suggestions once you type in 120 characters in your Grammarly editor.
The beta version of the new tone detector is now available in some of the popular browser extensions like Chrome, Firefox, and Safari. Apart from that, it works on services like Gmail, and Yahoo. The support for all types of text fields will be rolled out pretty soon.
