A safe space to say what you can't say in real life. You build the person you're angry at: who they are, how they talk, how they react when confronted. You describe what happened. Then you confront them, either in a Discord-style chat or face-to-face. The bot plays the recipient from your description only. Nothing new is invented to hurt you, nobody pushes you toward forgiveness, and you end it when you want. Fiction, not therapy.
