Ask Convaa 20 questions with no signup, no email and no card, then keep the thread when you join.
You can use Convaa before you tell it anything about yourself. Open the page, type a question, get a real answer from a real model. No email, no password, no card.
You get 20 questions that way. When you do decide to sign up, the thread you already started comes with you — the account is added to the work, rather than the work being thrown away and restarted.
You can also pull one other person into a guest thread before either of you has an account, which is usually a faster way to show someone what this is than describing it.
