Smart Reply is a feature in Inbox and Allo that suggests quick responses that are created by analyzing the email you received. Rather than pre-made quick responses, the suggested responses are relevant and in your style of writing.
Now when you view a message in Gmail, three smart replies are suggested for you. Once you press them, you can edit them before sending. The more you use this feature, the more Smart Reply learns and writes like you.
The feature is rolling out to Android and iOS users in English, with Spanish coming in the following weeks. Give it a shot and let us know what you think! And if you want more details on how it works, hit the source link.
