BlockBrain

GitHub Modrinth Gradle Fabric API Fabric

Overview

BlockBrain is a premium, seamlessly integrated AI companion built specifically for the Fabric ecosystem. Instead of relying on external browsers to query game mechanics, recipe sequences, or modification documentation, players can interface directly with an advanced AI framework native to the client runtime. Utilizing dynamic state injection, the engine actively reads environmental metrics to generate highly contextualized output without interrupting gameplay flow.


Key Features

  • Context-Aware Intelligence — Continuously monitors and injects live game states (including current dimension, active gamemode, biome, and loaded modifications) into query payloads to ensure maximum accuracy and relevance.
  • Asynchronous Engine Architecture — Operates on a non-blocking asynchronous networking layer, guaranteeing zero frame-time degradation or micro-stuttering during active query resolution.
  • Native Modularity — Includes complimentary access to the BlockBrain Cloud infrastructure out-of-the-box, while fully supporting Custom API Key integration (BYOK) for OpenAI, Groq, and OpenRouter for power users.
  • Dynamic Interface Design — Features a custom charcoal-and-blue minimalist aesthetic, complete with hardware-accelerated transition animations, a native markdown text renderer, and integrated toast notifications.

Installation Guide

  1. Dependency Verification: Ensure the target environment has the correct iteration of the Fabric API installed.
  2. Deployment: Place the compiled BlockBrain binary payload directly into your local mods directory.
  3. Initialization: Launch the runtime client (supported for versions 1.21 through 1.21.11).
  4. Interface Access: Press the Right Shift key or execute the /blockbrain command in chat to initialize the dashboard overlay.
