Google can now automatically suggest subject lines for email through Gmail's intelligent compositing feature. The new capability came to Gmail today, bringing us a little closer to a future in which we only use bots to replace our most mundane communications.
Smart Compose can already guess the next part of their sentences based on their writing habits, offering suggestions. when you are about to ask someone to "revisit this next week", or thank you at the end of an email. It is based on machine learning to make its recommendations, which Google says "can reduce the effort required to write emails and responses."
After writing the body of your email, Smart Compose can suggest a topic. For email based on your content. For example, Gmail might suggest the title "Happy birthday!" For an email to a friend about how to make birthday plans.
