VoxelMind - AI Companions

VoxelMind goes Local. The hosted VoxelMind service and all subscriptions end on November 8, 2026. Until then everything works as usual; new subscriptions are closed and existing ones will not renew. Playing through the hub, including on phones (Bedrock), ends with it. VoxelMind lives on as a free mod that runs entirely inside your game, with no VoxelMind account. Available now on this page (Files tab), for Minecraft 1.21 to 26.2 (Fabric). You choose the AI: Player2 (free), VoxelMind Sparks, your own OpenRouter account or a local model. Found a bug? Please report it on our Discord.

VoxelMind: AI beings that live in your Minecraft world

Free. VoxelMind runs entirely inside your game: no VoxelMind account and no subscription. Every decision is made by a language model, not by scripts. The mod shows it the world and carries out what it chooses.

Three kinds of AI beings

• Companion: a real player body. It walks, mines, fights, crafts, builds and talks with you in normal chat, and it remembers what you did together.
  • Normal mode (it respawns) or hardcore (one life).
  • Keep it in this world or take it into all your worlds.
  • Give it the skin of any Minecraft account.
• Builder: a fairy at your shoulder with console power. It fills areas, builds whole structures from a description, layer by layer, and undoes its edits.
• God: a bodiless game master. It improvises adventures with commands, rules and creatures. Pick a campaign and a chaos level from 1 (only blessings) to 5 (nothing is sacred).

Builder and God get console power, so only the host of a singleplayer world or an operator can bring them. Once a day, before one arrives, the mod writes a backup of the world.

Open the menu with V, the ♦ VoxelMind button in the pause menu, or /vml.

You choose how it thinks

• Player2 (free): connect a free Player2 account and get some AI power every day. Honestly, the free amount is small and only enough for short sessions. Player2 picks the model.
• VoxelMind Sparks: our own prepaid AI service with a tested standard model. One Spark is about one minute of play.
  • Sign in from the game with your Minecraft account, the same way you join a server: no password, no email.
  • Welcome Sparks once per Minecraft account, plus a few free Sparks every day.
  • Sparks never expire. Packs and prices: voxel-mind.com/sparks (also for another Minecraft name).
• Your own OpenRouter account: sign in inside the game and pick any model that can use tools. The list estimates the cost per hour. You pay OpenRouter directly; the default model costs about $0.20 per hour of play.
• A local model: Ollama, LM Studio or any OpenAI-compatible server on your PC. Free, if your computer runs a model with tool support.

Getting started

1. Install Fabric and Fabric API for your Minecraft version, then add this mod. If you have an older "VoxelMind Companion" file (0.4–0.8) in your mods folder, remove it: don't install both at once.
2. Join a world, press V and open the AI settings (or type /vml setup). Pick Player2, Sparks, OpenRouter or a local model, then press Test connection.
3. Create a companion in the menu, or type /vml summon Lysa cheerful, curious, a bit cheeky, and just talk to her.

Commands (/vml help lists them all)

• /vml: open the menu
• /vml summon <name> [character]: summon a companion, or call one to you
• /vml builder <name> [character]: bring a Builder fairy
• /vml god <name> [character]: bring a God game master
• /vml setup: AI settings
• /vml sparks: your Sparks balance and the shop

Versions: Minecraft 1.21 to 26.2, Fabric, Java Edition only. Fabric API is required. Works in singleplayer, on LAN and on servers that run the mod. Players joining such a server don't need it. On a dedicated server the operator connects the AI with commands; see voxel-mind.com/help.

Privacy: Characters, memories and logs are stored locally, in your world folder or game folder. Your chosen AI provider receives the prompts it needs to answer. With VoxelMind Sparks, our service only stores your Minecraft UUID and name, your balance and the cost of each request; we don't store chat content. Payments for Sparks go through Stripe.

Bugs: found one? Tell us on Discord, ideally with what you asked and what the companion did. The new files are called "VoxelMind Local … (your Minecraft version)".

Older files ("VoxelMind Companion" 0.4–0.8) are the hosted mod. They keep working until the hosted service ends on November 8, 2026, then they no longer connect. Your old companions and memories from the hosted service don't move over.
