Start with the job you want the app to do
Before comparing a long list of labels, decide what you want from the first minute. Some people want to author the whole premise: the setting, the cast, the conflict, and the opening line. Others want help getting past a blank start. Those are different jobs, and they lead to different ways of evaluating an AI roleplay app. If your goal is to participate quickly, look for a story entry that gives you a situation before asking you to perform. A useful opening contains something a character can notice, question, protect, or change. Keep the decision grounded in original material. You do not need a borrowed fictional world or famous character to know whether a beginning gives you enough to do.
