Open Dungeon is an AI-powered interactive fiction app that runs entirely on your own computer. You type actions, dialogue, or narration, and an AI narrator responds and continues the story. Both the text and any scene images are generated locally, meaning nothing is sent to an external server and no account or API key is required. For the text side, the app works through Ollama, a tool that runs AI language models on your own machine. It defaults to Google's Gemma 4 models, which come in several sizes ranging from about 4 GB to 19 GB of disk space, so you can pick what fits your hardware. If you already run your own AI server, you can point the app at it instead, since it supports any backend that speaks the OpenAI API format. On the image side, the app can generate scene illustrations inline as the story progresses. On Apple Silicon Macs this uses a model called FLUX, and on Windows and Linux it can use either a graphics card or the CPU. Getting started on a Mac with Apple Silicon is a drag-and-drop installer from the Releases page. On Windows there is a batch file launcher that checks for required software, installs missing pieces where possible, and sets up the image generation backend. A manual setup path is also available for anyone who prefers to clone the repository and run commands themselves. The story interface has three input modes. Do sends a player action that the narrator responds to in second person. Say wraps your text as spoken dialogue. Story lets you write narration directly into the story yourself. Above the text box, Continue lets the narrator advance the scene without any input from you, Retry discards the last response and regenerates it, and Erase removes the most recent exchange. You can also click Edit on any message to rewrite it in place. For long stories, the app keeps as much history in the model's context window as possible, up to 256,000 tokens on the larger models. When older story text would no longer fit, the app compresses it into a rolling summary so the narrator retains the plot without forgetting earlier events. All chats, characters, and images are stored in a local database on your disk.
