Lexikon
by Oiha
Lexikon checks spelling in Minecraft chat as players type, marking mistakes and offering corrections before a message is sent.
What it does
While a player types in chat, Lexikon highlights words it reads as misspelled and offers replacement suggestions. Live correction lets the player accept a suggestion as the text is being written, and a left click on a highlighted word shows the rule that flagged it. The checker covers English in both the US and UK variants.
The mod is a Fabric client mod: only the player's own game needs it, and servers do not have to install anything. It is published for Fabric across 21 release versions, with 1.1.1-1.21.8 for 1.21.8 as the latest file. Mod Menu and YetAnotherConfigLib (YACL) are required, so both must be installed next to Lexikon. The mod was first published on 2024-09-25 and last updated on 2025-07-22, and it is released under All rights reserved, so it is not open source. The source code and issue tracker are public.
Key features
Error highlighting
Words that do not match the dictionary are underlined in the chat input as the player types.
Live correction
Suggested fixes can be accepted while the message is still being typed, without leaving the chat box.
Correction suggestions
Each flagged word comes with a list of likely replacements ranked for the context of the message.
Rule explanations
A left click on a highlighted word opens the grammar or spelling rule that triggered the mark.
US and UK English
The checker supports both American and British English dictionaries for the same chat input.
