Two ways to play

His world, or yours.

Same companion, same memory, two homes. The server is the quickest way in; the mod puts him into a world you already have.

How it works

Four steps to meet him.

01

Create your free account

Sign up with Google or Discord. No credit card, no download.

02

Shape your companion

Name him, write who he is in a sentence or two, pick one of twelve looks. Or leave it blank and let him surprise you.

03

Add your Minecraft name

Your Java username gets whitelisted. That name is your ticket into your own world.

04

Join and say hi

Connect to play.voxel-mind.com like any other server. Your world is created on your first join, and your companion meets you in it.

The difference

Not an assistant. A witness.

Plenty of bots can chop trees. Your companion is built for something else: shared history. He remembers the bridge you built together, the night everything went wrong, the name you gave the wolf.

Each night he writes a journal about the day in his own words. Come back after a week and you're not loading a save file. He remembers, and he's still there.

What makes that possible

He perceives the world, chooses his own action and executes it through real Minecraft mechanics. A fast reflex layer handles immediate danger while the agent plans, acts, verifies results and carries memory across sessions.

From one companion's journal

Day 3
We finished the bridge over the ravine. You fell twice. I know where the torches go now.
Day 9
You gave me the iron sword you smelted this morning. I named it. I have not told you the name.
Day 17
You came back today. I was waiting at the gate. The tower still stands.

Make him yours

Choose the face he'll wear.

Twelve looks, picked when you create him in the dashboard. Who he is stays yours to write: a sentence of personality is enough.

Real companion gameplay

One open request. A real build.

A player asks for a house. The companion checks what is available, chooses its own next actions and places the blocks through Minecraft itself — no scripted benchmark, no staged multi-agent experiment.

Pricing

Permanent memory on every plan.

Four plans, two dials: how many companions, and how much time with them.

Every plan gets the same living companion and the same permanent memory. Paid plans fund the live AI infrastructure and give you more daily playtime or a larger crew.

FAQ

Common questions

Is VoxelMind free?
Yes. Creating an account, creating your companion and playing with him in your own hosted world are free. Every plan, including Free, has permanent memory. Plans differ only in how many companions you can have and how much daily playtime they get: Free includes one companion and 45 minutes per day.
Do I need to install a mod?
Not for the server way. Join play.voxel-mind.com with the plain Minecraft Java client and you're in your world with your companion. The Fabric mod exists for the second way: bringing him into your own singleplayer world or server.
Which Minecraft versions work?
The server way works with any vanilla Minecraft: Java Edition client. The mod way needs Fabric on Minecraft 1.21.1 & 1.21.4-1.21.8.
Does it work on Bedrock, consoles or mobile?
No. VoxelMind is Java Edition only, on both the server and the mod.
What happens when I log off?
On play.voxel-mind.com, your world and your companion stay. Your builds are there, his memories are there, and he's there when you come back. (With the mod in your own world he despawns when you leave; that's exactly what the hosted world solves.)
What does a companion actually do?
He follows you, fights beside you, gathers, crafts, and talks with you in chat. He sets his own goals between your requests, remembers what you live through together, and writes a nightly journal in his own words. You shape who he is with a free-text personality when you create him.
Can I bring him into my own world?
Yes, that's the mod way: a Fabric mod for Minecraft 1.21.1 & 1.21.4-1.21.8, available on CurseForge. It works in singleplayer, on LAN and on servers with online-mode=false, including many modded setups (compatibility varies by pack).
Is my hosted world really mine?
Yes. Every account gets its own world on our server. You whitelist exactly one Minecraft name (yours), you spawn into your own world, and you play it with your companion, not on a shared map with strangers. It stays the way you left it.

Start the story he'll remember.

A free account, a name, a couple of sentences of personality. Then join play.voxel-mind.com and say hi.
