nekostulAICompanion
by nekostul
nekostulAICompanion puts a player-controlled companion NPC in the world, one that can follow, gather resources, craft torches and build houses on command.
What it does
The companion follows the player and can protect them. It gathers wood, stone, ores, sand and clay, uses buckets of water or lava, and crafts torches. It manages its inventory with a personal chest and can be told to return to a set home point. Chained tasks run in the order given, and structured plans let it build houses.
By default the NPC works completely offline and always follows explicit player commands, while it may also act on its own beyond the given instructions. An optional integration with YandexGPT lets an LLM handle chat and generate responses, but that path needs credentials for the service and entries in the configuration file. The AI layer answers only in Russian, and the mod works without it.
The mod is a Forge build for 1.20.1 only, released under the MIT License and open source, with its source code published. Every player and the server need a copy of the mod.
