In plain English

Light Novel Studio is a browser-based writing tool that uses AI to help you write light novels in Chinese or Japanese. A light novel is a style of illustrated fiction popular in Japan and Chinese-speaking markets, often covering genres like fantasy, romance, sci-fi, and school life. You give the tool a single sentence describing your story idea, and it generates the full structure for you in steps: a world-building overview, a cast of characters with personalities and relationships, a chapter outline, and then the actual text of each chapter. The tool runs entirely inside your browser as a single-page web app with no server component. Your work is saved in the browser's local storage, meaning nothing is sent to or stored on any third-party server beyond the AI provider you configure. Your API key (the credential that lets the tool call an AI service) is also stored only in your browser and never uploaded elsewhere. You choose which AI provider to use: Google Gemini, Anthropic Claude, OpenAI, or any service that follows the OpenAI API format, which includes options like DeepSeek, Qwen, and locally running models via Ollama. You enter your own API key in the settings panel. Beyond the initial generation, the writing workspace includes tools for continuing a chapter with AI, generating dialogue between characters, and creating specific scenes. The interface shows paragraph indentation and line formatting in the style typical of the genre. Character profiles store appearance, personality, backstory, motivations, and relationship maps. The world-building panel keeps setting details consistent across chapters. The project is built with React, TypeScript, and Vite. It is licensed under GPL-3.0. The README is written in Simplified Chinese with an English summary at the top.
