by dormienkolo

With ReactiveNpc installed, a companion named Aria joins the player's world and answers in conversation, cooks, fights and keeps an inventory of her own.

What it does

Aria is an NPC companion that is driven by an AI model through the Groq API. Players talk to her in ordinary language, and her replies take the surrounding situation and the relationship built so far into account. Aria does not wait for commands: she acts on her own, so she can start cooking, join a fight or follow the player while they build, explore or sit by a fire.

The mod needs a free Groq API key before the AI features work. Aria has a personal inventory and a combat protection system, and she scans nearby furnaces to cook food without being told. ReactiveNpc is Forge only and is built for Minecraft 1.20.1. Every player and the server need a copy of the mod. The mod is released under All rights reserved and is not open source.

Key features

  1. AI-driven dialogue

    Talking to Aria produces context-aware replies, drawing on the current situation and her relationship with the player.

  2. Autonomous cooking

    Aria scans the area for furnaces and cooks food on her own initiative.

  3. Combat support

    She takes part in fights and has a protection system that defends her during combat.

  4. Personal inventory

    Aria carries her own inventory, separate from the player's, and can trade through menus.
