Getting started

Craftulator adds one item: a calculator you can open anywhere. Every key plays a note, so it doubles as a small instrument.

Install

1. Install Fabric with Fabric API, or NeoForge, for Minecraft 26.3.
2. Put the Craftulator jar in your mods folder.
3. Optional: add Curios (NeoForge) or Trinkets (Fabric and NeoForge) to wear the calculator in its own slot. See Curios & Trinkets.

Craft a calculator

Glass panes for the screen, stone buttons for the keypad, and a note block between two iron ingots for the body.

Shaped ➜ Calculator

The recipe unlocks in your recipe book once you pick up a note block. In Creative, the calculator is in the Tools & Utilities tab. It does not stack.

Open it

• Right click with the calculator in either hand, or
• press C while holding it or wearing it. See Keybind.

The game keeps running while the calculator is open. Press Esc or your inventory key to close it.

Where to go next

• Using the calculator: every key, keyboard shortcuts and how results are shown
• Musical keypad: which note each key plays, with tunes you can try in the browser
