Mneme by Olympus

Mneme keeps the things you'd normally alt-tab for inside the game. Notes, checklists, timers, a calculator that knows what a shulker box holds, and macros. Press N in game and it's all there.

It's client-side only, so it works on any server and nobody else needs to install it.

• Write notes and checklists. Each one gets a title, a word-wrapped editor, one of eight colors and a paper, plain or black look.
• Drop your coordinates in with one click. The Coords button writes your position and dimension where the cursor is, in a note or a checklist item.
• Reorder checklists. Drag an item by the grip on its left.
• Pin notes to your screen. Keep a shopping list or a build plan on the left or right edge while you play, scaled anywhere from 50% to 200%.
• Set timers. Pick a preset or type a time like 10m, 1h30m, 90s or 1:30. When it rings you get a toast and a sound, even if it ran out while the game was closed.
• Do Minecraft math. Type things like 3 stacks + 12, 2 shulkers / 5 or 1 dchest. Big results show up as shulkers, stacks and items, and your past calculations stay in a history.
• Link Nether portals. Turn Overworld coordinates into Nether ones and back. Pin a named portal spot and it gets light beams and a distance readout in both dimensions.
• Run macros. Write a script and pick what starts it: a key, joining a world, a timer, a chat message, dying, taking damage, low health or hunger, picking up an item, a villager trade, changing dimension, sunrise, rain and more.

A macro is a script with one command per line: say, command, echo, toast, sound, copy, wait, run, and the logic commands set, if with else, repeat, for, while, break, continue and stop. Blocks close with end. wait until pauses until a test is true, like health < 10. {x}, {y}, {z}, {dimension} and {player} work on any line, and so does any variable you make with set. Each trigger adds its own, like {message} in chat macros or {item} and {count} for items.

The editor colors your script, marks bad lines, completes commands as you type, and has a ? that explains every command.

say I am at {x} {y} {z}
wait 2s
repeat 3
  echo still here
  wait 1s
end
command time set day

Waits take ticks (20t), seconds (2s) or just a number of seconds. Lines starting with # are skipped. A loop that never waits runs one round per tick, so a mistake can't freeze the game.

Mneme draws its menu with Proteus, the same as Orpheus. You need Proteus 1.1.0 or newer. The Modern or Classic style, accent color, blur, animations and toast position are set once on the Proteus card at the top of the menu and apply to every Olympus mod.

Minecraft 1.20 to 26.3 on Fabric, Forge and NeoForge.

Pick the file that matches your loader and game version. Mneme needs Proteus 1.1.0 or newer, and Fabric also needs Fabric API.
