[aira]AIReplyAssistant
by O-Illusions
With AIRA, a chat assistant for Fabric, each player can receive DeepSeek-generated reply suggestions in multiplayer chat, shown as a list on the in-game HUD.
What it does
AIReplyAssistant, published as [aira]AIReplyAssistant by O-Illusions, sends chat context to the DeepSeek language model and returns candidate replies that the player can choose from. It recognizes which messages are system messages and which were written by the player, so suggestions follow the conversation rather than every line of text. Candidate replies appear in an in-game interface, and the player picks one with the keyboard.
The mod runs on the client alone, so players install it without any server-side component, and the server does not need to run it. Files exist for Fabric across six game versions, 1.21 – 1.21.5, and the latest file, Test-1.0, targets 1.21 and was published on 2025-06-16. Fabric API is required. The code is open source under the GNU General Public License v3.0 only, and the public source repository is linked from the project page.
Key features
DeepSeek reply generation
Chat context is sent to the DeepSeek API, which returns natural language reply options written for the conversation.
Candidate reply display
Several reply options are listed in a HUD panel, so the player compares them before sending anything.
Auto-reply mode
When enabled, the mod answers messages from other players automatically, without a keypress for each one.
Keyboard selection
Double-pressing Tab generates the candidate list, and holding Tab with a number key from 1 to 6 sends the matching reply.
Customizable prompts and parameters
Prompts and API parameters can be adjusted, so the replies can be tuned to the style the player wants.
