Figure 1: Our system allows users to generate story ideas by providing a set of inputs, which can include tropes and text, e.g., the Starfish Aliens trope and "Falling in love?" (left). Leveraging trope knowledge extracted from tvtropes.org, our suggestion algorithm automatically surfaces relevant tropes as story ideas with additional information (middle). Users can add some of these suggestions to their canvas, e.g., Humanity is Infectious and Interspecies Romance (right). Through iteration with the system, users can ideate and develop their stories.
