About this Mod

Illcalibour's AI Chat is a Fabric client mod for Minecraft 1.21.8 that adds an AI chatbot to in-game chat using a local Ollama model (default: qwen2.5:3b).

When you send a trigger message (for example Hey AI ...), the mod sends the prompt to your local AI backend and posts the response in chat. By default, AI replies are sent to server chat so all players can see them. Triggers, model settings, and behavior are fully configurable in Mod Menu.

Features:

  • Configurable trigger prefixes (Hey AI, KI mach, etc.)
  • Toggle AI feature on/off
  • Option to send or block the trigger message
  • Option to send AI replies to server chat
  • Local AI backend support via Ollama
  • In-game configuration via Mod Menu + Cloth Config

Requirements:

  • Minecraft 1.21.8
  • Fabric Loader
  • Fabric API
  • Mod Menu
  • Cloth Config
  • Java 21
  • Ollama running locally
  • Recommended model: qwen2.5:3b

How to run:

  1. Install Ollama (https://ollama.com/download)
  2. Open a new Powershell and paste in following command "ollama pull qwen2.5:3b"
  3. Start Minecraft and chat with your new AI friend

This project was fully programmed with AI and inspired by l33T on YouTube.
