Story World Builder

Webtoon Novel Plot & Character

Free · Designed for iPad. Not verified for macOS.

Story World Builder is a story-planning tool designed by webtoon and web novel professionals. When an idea strikes, when you're shaping a character, when the plot gets stuck — it's with you at every step of creation. Key Features 1. AI Scenario Ideas Pick a few keywords and AI suggests 3 distinct story frames. Choose the one you like, and it even expands into a draft plot for Episode 1. 2. Worldbuilding Record your world systematically — background, rules, magic systems, and places. The AI worldbuilding assistant helps you expand settings and check for contradictions. 3. Character Management Design characters in detail: personality, MBTI, appearance, and abilities. See how everyone connects at a glance with the relationship map. 4. Storyline Visually build timelines where multiple characters' stories intersect. Compare each character's actions across time periods at a glance. 5. Plot Builder Structure your story with episodes, scenes, and cuts. AI suggests next-scene ideas, plot twists, cut ideas, and plot feedback. 6. AI Writing Assistant Dialogue, name ideas, scene ideas — AI is there whenever you're stuck. Conversations are saved per project so you can pick up where you left off. Good to Know - All creation features (worldbuilding, characters, plot, storyline) are free as a launch event. - AI features are free 5 times a day. (Expanded while the Pro subscription is being prepared) - A Pro subscription with more AI features is coming soon. It's time to bring your story into the world. Start with Story World Builder!
