About
StoryAI (STORYAI) is an AI-powered creative assistance platform developed by ZEAL CORPORATION, designed specifically for writers, novelists, bloggers, and content creators seeking objective feedback and AI-driven support. At its core, the platform leverages Plutchik's Wheel of Emotions—a psychological model of human emotion—to numerically analyze the emotional composition of text and images, helping creators visualize the emotional arc of their work through graphs and data. The platform solves three key creator pain points: lack of objective feedback, the difficulty of articulating ideas into words, and uncertainty in concept development. Users can input a single opening sentence and have the AI automatically generate a full story or article continuation, choosing from multiple language models. Generated content can then be analyzed, summarized, and iteratively refined through repeated AI feedback loops. StoryAI also accelerates character development by generating detailed character profiles and matching thumbnail images instantly. Its word cloud feature helps technical bloggers and writers spot inconsistencies in terminology and phrasing. The platform holds a Japanese patent (Patent No. 7368684) for its underlying technology. With a freemium pricing model starting at ¥0/month, StoryAI serves hobbyist writers, students in creative disciplines, and professional authors who want to accelerate their creative workflows with measurable, data-driven improvement insights.
