24 alternatives to Open-Source AI Tool for Crafting Custom D&D Campaigns

Hey everyone, DNDGenerate is my little adventure into the world of AI and D&D. I wanted to learn more about using ChatGpt to build software and about the openai apis. When I saw how much fun my 9-year-old was having, creating his own D&D worlds. That got me thinking – why not make a tool that uses ChatGPT to help build cool D&D campaigns?

   ChatGPT-powered dystopia simulator▲195

   OP here. This comment contains SPOILERS so try the dystopia simulator first before reading further! I built "WeChatGPT+" in December on top of GPT-3. It was pretty surreal when OpenAI released an actual product named "ChatGPT Plus" a few months after that. Then the Microsoft partnership was announced, Bing AI was released, and marketing materials were leaked indicating that Bing AI would start including advertisements within the chat responses. Reality imitates fiction, I guess. Today - literally a few hours ago - OpenAI announced public ChatGPT API with 10% the cost of GPT-3. I immediately…
