AiModeration
AiModeration screens chat on a Fabric server, with an AI model marking messages for toxicity, spam, advertising and grief threats as they arrive.
What it does
The mod watches chat in batches of 20 lines. Each batch is sent to an AI provider, which reports messages that contain toxicity, spam, advertising or threats against other players. Supported providers are OpenRouter and Groq, and three model tiers can be chosen per provider.
When a flag comes back, the mod can apply the punishment it suggests on its own: a warning, a kick or a ban. Those actions run straight from the server console, so no moderator has to be online for them to take effect.
The server side is the only part that runs. Players join without installing anything, and the mod also exists as a Paper and Purpur plugin for PaperMC 1.21.x servers. Settings and command details are described in the GUIDE.md file that ships with the mod, and the code is released under the MIT License, not as open source.
Key features
Batched AI analysis
Chat is grouped into batches of 20 lines and sent to an AI model, which flags messages by category.
Automatic punishments
Suggested warnings, kicks and bans can be applied without a moderator stepping in, using commands from the console.
Provider choice
OpenRouter and Groq are supported, with three model tiers to balance analysis detail against cost and speed.
Audit logging
Flagged messages go to chat-msg.txt, and every action goes to a permanent chat-action.log trail.

Use cases
Who it’s for: Server owners who run Fabric, Paper or Purpur servers and want chat screened automatically. Players need nothing installed on their side.
How it compares
Among the alternatives, ChestWarning and Blocketing are server-side only and open source under the MIT License, but they cover chest protection and blocking rather than chat screening. Quick Actions is a client-side Fabric mod for 1.21.8 – 1.21.10 and is not open source, so it does not run on servers at all.
