Based on what you enter in the draft and nuance fields, AI Reply generates a reply message. By entering the recipient’s type (friend, boss, etc.), the tone will match the person you’re replying to. There is also a feature to brush up the generated reply suggestions, so please give it a try. We also added “On hold” to the three stances. Use it when you want to avoid giving a clear answer but still want to send a quick reply for now. In addition, we’ve made minor improvements. Thank you for using AI Reply.
