What it does

Messages typed by players are sent to ChatGPT and the answers are posted back to the server chat. The mod runs on the server alone, so players join without installing anything. It requires Fabric API and is released under the MIT License as open source, with builds for 1.21.3 and 1.21.5.

Key features

  1. ChatGPT in chat

    Players can talk to ChatGPT directly from the server chat, with replies shown to the sender.

  2. Server-side messaging

    Messages are sent to ChatGPT from the server, so clients need no extra software.

  3. Item rewards

    The mod can give an item to a player, which server owners can use as a reward or prize for interacting with the AI.
