Chat autocomplete
by Dev1938473
Chat autocomplete suggests the rest of a message as a player types it in the Minecraft chat box, based on text the player has sent before.
What it does
Typing in chat triggers suggestions built with a Markov chain, a model that predicts the next word from the words that came before it. The model learns from the messages a player sends through chat, so the suggestions reflect that player's own communication patterns. Early on the suggestions are weak because little data has been collected, and they improve as more messages accumulate.
The data is stored locally in a file named markov.json inside the Minecraft config folder. It is used only to improve the player's own experience and is never shared with anyone. The mod works with English only. Because the stored file grows with use, it can reach several megabytes after a long time in use, and it can be deleted from the config folder to start over.
Chat autocomplete requires Fabric API. It runs on the client alone, so the server does not need it, and it is published for Fabric only, with a single build, 1.0.0 for 26.2, released under the MIT License. The project is not open source.
Key features
Markov chain suggestions
Suggestions are generated from a Markov chain that predicts likely next words from the player's earlier messages.
Learning from chat
Each message a player sends through chat adds to the model, so later suggestions better match how that player writes.
Local data storage
The learned patterns are saved in markov.json within the Minecraft config folder and are never sent elsewhere.
English only
Suggestions are generated for English text, and no other language is supported.

Use cases
Who it’s for: Players on Fabric 26.2 who write mostly in English and want chat suggestions drawn from their own messages. Server owners do not need to install it, since it is client-side only.
How it compares
Hypixel Autocomplete is a Fabric client mod for versions 1.21.5 – 26.3, released under the GNU General Public License v3.0 only and open source, while Chat autocomplete is only for 26.2 and is not open source. Emoji Chat is also client-side only on Fabric for 26.2, but it is under All rights reserved and not open source, and it adds emoji rather than suggestions.

What the author says
This mod allows faster typing and less typos in the minecraft chat with an adaptive Markov chain algorithym that learns communication patterns. The autocomplete might feel stupid at first, but as it gets more data, it should get better. The only language supported for now is english. There is currently no autocorrect…
