PaT
by tom_dev
PaT is a Fabric companion mod that places a friendly AI character inside a Minecraft world, with whom players can chat, trade notes and build a relationship.
What it does
The companion joins the game and greets players when they arrive. Over time it leaves short notes on signs around the world, keeps the player company during night sessions and asks questions to get to know the player better. Ambient sounds are added as well, so the world feels more alive when the companion is present.
Journal entries from the companion are hidden throughout the world for players to find. Friendship develops through the choices a player makes in conversation. The companion uses only in-game information to personalize the experience, and it is described as a digital pen pal for players who enjoy the game.
PaT runs on Fabric and is published for 1.21.11 only, with the latest file 1.0.3 dated 2026-05-31. It is a client and server mod, so the server and every player need it, and it can also be used in singleplayer. The code is released under the MIT License, but the project is not open source.
