[AdvancedChatBox] Simply Updated
by Nordes
With AdvancedChatBox Simply Updated installed, the Minecraft chat box gains complex tab suggestions, spell checking and an in-chat calculator on Fabric.
What it does
This Fabric mod is an updated build of the original AdvancedChatBox, with fixes applied to the earlier code. Its suggestions go beyond plain tab completion: a player typing in the chat box can get spell checking through a LanguageTool-based proofreader, a calculator that evaluates expressions inline, and a JSON linter available as built-in commands. Players can also switch player-name suggestions on or off and change the colors used for suggestions.
The mod requires AdvancedChatCore Simply Updated, which must be installed alongside it. It is installed on the player's side alone, so servers need nothing. Its files target game versions 1.21.11 – 26.3, and the source is released under the Mozilla Public License 2.0, which makes the project open source.
