I spent the day noodling with RAG (retrieval-augmented generation) mechanisms to create MergrimAI, an LLM that is able to act as your remote game master. MergrimAI can look up information from the core rules and the game master’s guide, on demand. You can ask MergrimAI about any rules context, from game mastery to specific abilities to overworld play and airships.
Some tips for MergrimAI: always pick the right context before querying. All the system's abilities (such as spells, tactics, status effects, archetypes, etc) exist in the "Reference Tables" context, so if you ask MergrimAI to tell you the text for the spell Overgrowth and you don't have that context selected, he won't be able to find it! You can set the context with the context dropdown.
Also, keep in mind that while we've done our best to minimize Mergrim's capacity to hallucinate, he still will. He's only artificially generated, after all. Always verify the core rules on the site if your ruling is super important to get right!
