Gmail compose window is small and composing, and correction takes lots of time. Google has introduced Smart Compose in Gmail, which will help you to autocomplete Gmail text when you write.
During the composing of an email whatever you write in the Gmail compose window, it will predict the text. With the help of the autofill feature, you can write an email effectively.
When you write an email to someone Smart compose allows you to write in a better way by suggesting some useful phrases or words.
Smart compose is a Gmail smart feature for users who use Gmail on their desktop. It will help you to write emails faster and better by suggesting words and phrases.
