Hello Martin, We’re sorry you had this experience. We just launched this app, and due to the high costs of AI, image generation, and narration - we decided to limit free accounts to no continuations. However, we’re working on a way to allow free users more stories and more continuations, and once it’s ready we can award your account with free credits to try it out! In the meantime, I ask that you remove the review as it hurts our launch greatly.

@The Prompt Challenge

Great way to improve you prompting skills through daily exercises. This should be implemented in schools, would really help students. Can also see it being really valuable for adults. Not just for prompting, but for articulation in general. Also made a video about it: https://www.youtube.com/watch?v=A8ZRJgLCFy8
