Ask ChatGPT

Customizable ChatGPT integration for Foundry VTT.

Allows you to leverage the power of AI in your game chat. It can help you out with questions regarding rules, items, spells, creatures, conditions, and so on. But most importantly it can be used as a powerful improvisation tool, helping you come up with sensible things on the spot, as well as plan ahead. The module supports both GPT-3.5 and GPT-4 models, and allows both GMs and players to have conversations with ChatGPT tailored to your game system or campaign.

How to use

First enter you OpenAI API key in the module settings. Some popular game systems, such as D&D 5e are automatically detected and supported w/o additional customizations. For others you may customize the ChatGPT prompt.

After that simply ask ChatGPT in the Foundry VTT chat!
