About QuestForge: AI Dungeon Master

QuestForge is a persistent, text-based TTRPG engine that runs 100% locally on your laptop, powered by Grok-4 as the dungeon master. It automatically saves campaigns to disk, tracks state across thousands of messages, and includes real dice rolls, full character sheets, inventory, spell slots, conditions, gold, and time-of-day tracking. Compatible with D&D 5e, Cyberpunk RED, Call of Cthulhu, Pathfinder, and any homebrew system. The open-source app is built with Flask and simple HTML/CSS/JS, can run on a Raspberry Pi, and is completely private except for API calls to Grok. It supports co-op play by opening multiple browser tabs and copy-pasting actions, with Grok tracking each character separately.

FAQ

Why use Grok instead of a local model like Llama or MythoMax?
Grok tracks state perfectly across thousands of messages, is sarcastic when appropriate, ruthless when deserved, and genuinely funny. Local models tested (Llama 3.2 8B, MythoMax, Dolphin-Mixtral) had issues with memory, lying about HP, or breaking character. Grok feels like a human DM who read the entire rulebook.
How do I get started with QuestForge?
Get a free/paid xAI API key from https://x.ai/api, clone the repository (or copy the two files: app.py and index.html), create a .env file with XAI_API_KEY and GROK_MODEL=grok-4, install Flask and dependencies (pip install flask python-dotenv requests), then run 'python app.py' and open http://localhost:5000. Type 'Start a new adventure' to begin.
Is QuestForge really free?
The tool itself is free and open-source. You do need your own Grok xAI API key, which has a free tier. The entire code is provided at no cost.
Can I play with friends?
Yes, co-op is supported by opening two browser tabs and copy-pasting actions. Grok tracks both characters separately, but it is not native multiplayer.
