Gemini in Minecraft
Gemini in Minecraft puts a Google Gemini AI chat window inside the game, where a player can ask questions and get replies without leaving the world.
What it does
Replies appear directly in the chat window. The assistant can answer questions about the world and can also carry out in-game commands. Each query is sent with live game details, so an answer can refer to where the player is standing and what they are carrying.
The context sent with a query covers player coordinates, current dimension, time of day, weather, game difficulty, health, food, experience level, inventory and equipped items. A server owner can shape the assistant's behavior through the system message, which takes dynamic variables that the mod swaps for live game values each time a query is sent.
Fabric API is required. The mod runs on the client alone, so a server does not need it and players join without installing it. Files are published for Fabric across 9 release versions, 1.21 – 1.21.8, under the MIT License, and the source code is open source.
Key features
In-game AI chat
Players ask questions in the chat window and read the answers there, without switching to a browser.
Context-aware replies
Each query includes the player's coordinates, dimension, time, weather, difficulty and vital stats.
Dynamic system message
The system message accepts variables that are replaced with current game values before each query is sent.
Editable configuration
A geminiinminecraft.json file is created in the config directory on first run, and the in-game setupai commands change the same settings.

Use cases
Asking about the world
A player can ask where they are, what the weather is doing or what their inventory holds, and the answer uses the current state.
Custom assistant behavior
A pack maker can write a system message with variables to set the tone and focus of the assistant for their players.
Who it’s for: Players who want a chat assistant inside a single-player world, and pack makers who want to tailor how the assistant responds to game state.
