The same sentence can mean very different things depending on who sends it. The MBTI translator takes a message, your MBTI type, the other person’s type, and your relationship, then explains the likely intent behind the words and suggests a reply that lands the way you want.
You paste what someone said, choose your type and theirs, and pick your relationship — partner, friend, family, or colleague. The translator then reads the message through both personality lenses and surfaces the most likely meaning instead of the literal words.
It is most useful for the messages you read three times before answering: a suddenly short reply from a partner, a terse note from your manager, or a comment from a friend that you cannot quite place. Seeing the same words through a different type’s defaults makes the intent easier to read and your response easier to write.
