AdvancedChatBox Reforged
AdvancedChatBox Reforged upgrades the chat input box with inline spell suggestions, a calculator, and command highlighting, and it is available for Fabric on 26.1 – 26.3.
What it does
The mod reworks the chat input line. While a player types, it marks misspelled words and offers corrections sorted by how close they are to the typed word, so the suggestion closest to the input appears first. Command highlighting and custom suggestions make commands easier to enter, and an in-chat calculator evaluates expressions typed into the box.
Spell checking relies on the LanguageTool engine, which ships with the mod. Its language data is large, so each language lives in its own small add-on, and the game language is selected automatically when one is installed. When no add-on is present, the other features still run and spell checking stays disabled.
The mod requires AdvancedChatCore Reforged, Fabric API and MaLiLib. It is a rebuilt version of the original AdvancedChatBox by DarkKronicle, with builds for 26.1, 26.1.1, 26.1.2, 26.2 and 26.3 and Java 25 as the runtime. Players add it to their own game, and a server needs no copy. The code is open source under the Mozilla Public License 2.0.
Key features
Inline spell suggestions
Misspelled words are underlined as the player types, with corrections listed beside the input.
Calculator in chat
Expressions typed into the chat box can be evaluated in place, without leaving the game.
Command highlighting
Commands are colored and given custom suggestions, which makes long commands easier to check before sending.
