Story World Builder is a story-planning tool designed by webtoon and web novel professionals β for when an idea strikes, when you're shaping a character, when the plot gets stuck. Key Features 1. Chat with Your Characters (AI Pass) Talk directly to the characters you've created. They answer as themselves, drawing on the personality, speech, relationships, and world you wrote. 2. Build a Scenario β on a proven story structure Pick a few keywords and a story structure, and AI proposes three scenarios in different directions. Ki-Sho-Ten-Ketsu, Three-Act, Five-Act, the Story Circle, the Hero's Journey, or Save the Cat β instead of a blank page, work through a structure that has carried stories. Pick one and it expands into an Episode 1 plot draft, with its cast added to your Characters in one tap. 3. Worldbuilding Record your world systematically β background, rules, magic systems, and places. Write what doesn't exist in your world in the "Taboos / Limits" field, and the AI won't cross that line in any suggestion. The AI assistant expands settings and checks for contradictions. 4. Character Management Design characters in detail β personality, MBTI, appearance, abilities β and see how they connect on the relationship map. 5. Plot Builder Structure your story with episodes, scenes, and cuts. AI suggests next scenes, twists, cut ideas, and feedback. Foreshadowing list (AI Pass): what you planted and where it pays off. Anything past due moves to the top. Setting Check (AI Pass): AI finds conflicts with your characters and world, and flags unpaid foreshadowing. 6. Write a Full Episode Manuscript (AI Pass) Turn an episode you've filled out into prose you can publish, following what you wrote β world, characters, relationships, and your "Taboos / Limits". It picks up the flow of earlier episodes and the voice of your last manuscript, so names and tone stay steady. Ask for a revision β change only the part you picked, or rewrite it all. 7. Timeline See how characters' stories cross on a subway-style map: one colored line per character. Tap a stop to expand it; tap a name to follow one character. With world, characters and plot already built, AI fills in what each character is doing at each hour in short lines. 8. AI Writing Assistant - Start from a scene you have in mind: write down one scene and we build the project and its world from that alone. - Naming Studio: pick what you're naming β character, place, faction, magic, item, or monster β add a mood, and get 15 names that fit your world, each with a note on how it reads. - Dialogue and scene ideas whenever you're stuck. - Mood presets: romance, fantasy, mystery, slice of life, dark, or comedy. 9. Export as PDF, Word, or Markdown Pick the sections you want β world, characters, scenario, plot, foreshadowing, manuscript, timeline, scene memos β as one PDF, a Word file, or Markdown for Obsidian or Notion. The relationship map comes as an image, and the PDF opens anywhere. Good to Know - One project is free, with all creative features, saving, and export. - The AI Assistant is free for 5 uses a month. Each character's first hello is free too. - For more projects, AI uses, chat, manuscripts, or Setting Check, subscribe to AI Pass. Manuscripts: Light 2 a month, Standard 6.
