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

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