Iron AI
Iron AI gives the in-game chat a reply system: it watches for keywords and answers with messages that players can teach, rename and reset.
What it does
Players add replies in-game with simple commands such as ironai teach, and ironai forget removes a word it has learned. The commands are kept short on purpose, and ironai help lists the ones available. When a keyword has several taught replies, one is picked at random each time it appears, so the answers vary.
What Iron AI learns is written to a file, so its memory stays after the game is restarted. The mod is meant for role-play, community servers and anyone who wants a chat companion with a personality shaped by its players, and it adds character interaction to a world or server. It is a Fabric mod for 1.21 – 1.21.6, released under the MIT License, and it is not open source. Either side can run it: it works on a client alone, a server alone or both, and neither needs it.
Key features
Keyword-triggered replies
Iron AI detects chosen words in chat and answers with messages that carry its own personality.
Teaching new responses
New words and replies are added during play through the ironai teach command, with no file editing needed.
Forgetting words
The ironai forget command removes a specific word from what Iron AI has learned.
Random multiple replies
A single keyword can have several taught responses, and one is chosen at random for each reply.
Saved memory
Learned words persist in a file, so the assistant keeps what it knows after a restart.

How it compares
ChatLogic is open source under the MIT License, works on Fabric for 1.21 – 1.21.11, and is client-side only, so it changes nothing on a server. Just A Chat Mod is also client-side only and not open source, with Fabric files for 1.21 – 1.21.5. Persistent Chat is open source under the MIT License, runs on Fabric for 1.21.1 – 26.1.2, and works on either side, so a server or a client can run it alone, and neither side needs it.
