Open dungeon Generates Private AI Stories And Images Locally

Open-dungeon is a fully local AI roleplay application that generates both text stories and inline scene images directly on your computer. It works entirely offline without needing any accounts, API keys, or cloud services. Your stories never leave your machine because all processing happens locally on your own hardware.
Developer Newideas99 created this project to bring private AI roleplay to personal computers. They designed the app to use Google's Gemma 4 models through Ollama for text generation and FLUX models for creating images. The creator built this tool so users could experience interactive fiction without sending their data to external servers.
Features and gameplay elements
- Generates text and images entirely locally.
- Offers Do, Say, and Story input modes.
- Maintains long story memory with rolling summaries.
- Connects to any OpenAI-compatible text backend.
- Allows playing from your phone via Tailscale.
This application is built for people who want to run interactive fiction models on their own machines without relying on internet services. Users with high-end hardware can take advantage of large context windows to keep entire story histories active during play. Anyone who values data privacy will appreciate that all chats, characters, and generated images remain stored in a local database on their disk.
Technical details and system requirements
The software defaults to a safer context window on Windows to prevent the user interface from freezing during slow requests. Mac users can download a simple installer, while Windows users need to run a batch file that handles all setup and dependency installation. The image generation feature is completely optional and runs through a separate background worker if the user chooses to enable it.
