IF is a What-If branching story creation app. Based on an existing work, you can start from a pivotal choice, a character relationship, or an established ending, write a different fate, and keep extending that new worldline. Whether you want to rewrite a single moment, reshape a relationship, or let a story continue beyond where it once stopped, IF helps turn the “what if” in your mind into a fully unfolding new storyline. From one key divergence point, you can explore alternate directions, different endings, and continuations that go beyond the original work. In IF, every branch is more than just an idea—it is a worldline that can keep expanding. Characters, relationships, and consequences continue to evolve through a new chain of cause and effect, letting you see another fate that truly holds together. Start with one “what if.” Write the version of the story that never got to happen.
