AI beings that live in your Minecraft world: a companion who plays next to you, a fairy who builds, and a game master who improvises adventures. The mod is free, the code is open, and you choose how your AI thinks.
Everything the mod remembers stays on your PC.
Three kinds of AI beings
Summon the one you want with a command or from the in-game menu. Each one decides for itself what to do.
Someone at your side
A real player body that walks, mines, fights, crafts and talks. You give it a name, a character and the skin of any Minecraft account.
A fairy with console power
A small glowing fairy that follows you. Tell it what you want in chat: it fills regions, builds whole buildings from a description, and can undo what it built.
A bodiless game master
No body, no name tag, just a presence that improvises adventures: commands, rules, creatures and surprises while you play.
Press V (or /vml) to summon, edit, monitor and read memories. No config files needed.
Give your companion the skin of any Minecraft account, for example your own or a friend's.
Characters, memories and logs live in your world folder or game folder, not on our servers.
Works in your own world, on LAN and on servers that run the mod. Players who join do not need it.
You choose the brain
The mod does the playing. The thinking comes from the AI you connect. Switch any time in the settings (V, then the settings pill, or /vml setup).
Connect a free Player2 account and get daily AI power at no cost.
Trade-off: Free, but Player2 picks the model and the free daily amount is small: enough for short sessions.
Our own prepaid AI service with a tested standard model. Sign in from the game with your Minecraft account: no password, no email.
Trade-off: Zero setup and a model we tested for the mod. Free Sparks first, then you pay for what you use.
Sign in to your own OpenRouter account inside the game and pick any model from its list.
Trade-off: Most choice, and you pay OpenRouter directly. Needs some credit on your account.
Run a model on your own PC with Ollama or LM Studio and keep everything offline.
Trade-off: Free and private, but needs a capable computer, and small models can struggle with tool-heavy tasks.
VoxelMind Sparks
Sparks are credits for our AI service at api.voxel-mind.com. One Spark is about one minute of play with the standard model.
Open source
The VoxelMind mod is free software under the MIT license. There is no VoxelMind account to create. What your companions remember stays in files on your own computer.
Fabric, Minecraft Java Edition. Requires Fabric API.
From the blog
On November 8, 2026, my servers go offline. VoxelMind doesn't: it moves into your game as a free, open-source mod for Minecraft 1.21 to 26.2. Here's what changes, why I'm doing it, what we still know about you (very little), and where this is heading: the VoxelMind Platform.
Yes. The mod is free and open source (MIT). Thinking costs compute, so you pick an AI: Player2 and local models can be free, Sparks and OpenRouter are pay-as-you-go.
Not for the mod. Depending on the AI you choose you sign in to Player2, OpenRouter, or with your Minecraft account for Sparks. A local model needs no account at all.
For a short free try, use Player2 (the free daily amount is small). For zero setup with a model we tested, use Sparks. For the widest choice of models, use OpenRouter. For full privacy and no ongoing cost, run a local model if your PC can handle it.
Fabric on Minecraft Java 1.21, 1.21.1 to 1.21.11, 26.1, 26.1.1, 26.1.2 and 26.2. Fabric API is required. Java Edition only.
Yes, on servers that run the mod. Players who join do not need to install it. Server operators set the AI with commands, see the help page.
Memories, characters and settings are stored locally on your PC. Your AI provider receives the prompts it needs to answer. With Sparks we keep a balance and a usage ledger, but no chat content.
Install the mod, press V and summon someone.
