Can I match a particular text? (For example when writing a reply to an email).
You can use Smart Reply option to match your answer according to your addressee's text. In this case, your reply will be analyzed directly against the person you are answering to. Moreover, you can create an Individual Profile Template from your addressee's text and save it for future use.
Just keep in mind the purpose of your communication. You may not want to match an angry tone expressed in an email from a customer if you want to lead the customer towards a more positive sentiment.
