Character Card Generator is a self hosted web app for building character files that work with SillyTavern, a popular AI chat interface for role play conversations. Instead of writing a character's description, personality, and opening message by hand, you type a rough idea into the app, choose a genre preset like fantasy, sci-fi, or horror, and an AI model fills in the rest, including an optional portrait image. The app runs in your browser after starting a small local server, either by double clicking a launcher file on Windows, Mac, or Linux, or by running npm install and npm start if you already have Node.js. It ships with its own bundled copy of Node so most people do not need to install anything separately. Once running, it opens in your browser with three panels: settings on the left, the character description you type in the middle, and a preview of the generated result on the right. For text generation, it can connect to a locally run KoboldCPP server, or to cloud services like OpenAI or OpenRouter using your own API key. For the portrait image, it supports a local ComfyUI setup or cloud image services including OpenAI's image models, Grok, or OpenRouter. Any API keys you enter are encrypted on your machine before being stored. Finished characters can be saved to a personal library and exported as PNG files with the character data embedded inside, in the format SillyTavern expects, so they can be dropped straight into that app. The author built this because they could not find an existing character generator that worked well enough for their own SillyTavern use, and made it themselves. The project carries a clear warning that it is meant to run only on your own machine, since exposing it to the open internet could leak stored API keys.
