Someone to share your Minecraft world with

VoxelMind adds AI companions who can explore, gather, craft, build and fight alongside you. Give your companion a name, write their personality in your own words, and meet them in your world. Your conversations and shared experiences become part of a memory that carries across sessions.

Talk through Minecraft chat or use push-to-talk and spoken replies. Choose a microphone and voice in the mod, test your microphone locally, and decide whether to review a recording before sending it. When several companions speak, their replies play through one shared voice queue.

What is in 0.8.8

• Survival companions: a second player in your world, with their own inventory and actions. Explore together, ask for help with resources, or just talk while you play.
• Builder preview: a visible companion with building tools for your own world.
• God preview: a companion who can act on the world without a player body.
• Voice: push-to-talk, streamed replies, microphone selection and male/female voice choices. The Voice screen shows your remaining monthly time and renewal date.
• Appearance: a skin picker with collections by plan, plus player-name and PNG imports on Premium.
• Memory on every plan: remembering your shared history is included in Free as well as paid plans.

Builder and God are previews for your own integrated singleplayer/LAN world. Their setup explains the local permissions they need. Companions can make mistakes and have their own ideas; their actions and conversations emerge from what is happening in your world.

Supported versions

Minecraft Java, Fabric: 1.21, every patch from 1.21.1 through 1.21.11, 26.1, 26.1.1, 26.1.2 and 26.2.

Download the JAR for your exact Minecraft version. Install the matching Fabric Loader and Fabric API. Minecraft 1.21.x uses Java 21; Minecraft 26.x uses Java 25. This is a client mod for Java Edition; there is no Forge, NeoForge or Bedrock build.

Get started

1. Install Fabric Loader, Fabric API and the VoxelMind JAR for your Minecraft version.
2. Open your world and press V.
3. Sign in with a free account at voxel-mind.com.
4. Create a companion, choose a mode and follow the setup shown in the mod.
5. Spawn your companion and start chatting. Open the Voice screen when you want to speak aloud.

The AI runs on VoxelMind's servers. You need an internet connection, but no AI API key or local AI model. For Survival companions in singleplayer and LAN, the built-in tunnel handles the connection without port forwarding.

Playtime and Voice

Current plans for new accounts:

Playtime is counted for each active companion. Offline characters do not use an active slot. Voice has one shared monthly allowance for recorded input and spoken output. If Voice time runs out, text chat remains available while you still have playtime.

Existing accounts can retain earlier playtime allowances. Your account shows the allowance that applies to you, your remaining time and the next renewal. Current prices, skin collections and subscription details are at voxel-mind.com/pricing.

Multiplayer and mod compatibility

Survival companions join as independent network players. Dedicated servers must allow their connection; the current setup requires online-mode=false. That setting disables the server's usual Minecraft account verification, so use the access controls described in our server setup guide. Minecraft Realms is not supported.

Client mods such as shaders, performance mods and minimaps are generally compatible. Content mods vary: a companion may not understand modded blocks, items or mechanics, and servers that require every joining player to load specific client mods can reject the connection. Send us the modpack and error message on Discord if a world will not connect.

You can also visit the VoxelMind hub at play.voxel-mind.com with a vanilla Java client. The mod is the way to bring companions into your own world. See the website for the hosted-world setup.

Account and data

The AI receives game observations and conversation to respond and act. Voice input is sent for transcription when you submit it; microphone access and spoken replies are controlled in the mod. Your complete world save is not uploaded as an AI input. Read our privacy information and safety information for details, including regional age requirements.
