OGLinter
by starfi1702
OGLinter is a client-side Fabric mod that checks grammar and spelling in the Minecraft chat box as the player types, with suggestions shown under flagged words.
What it does
Grammar and spelling checks run through LanguageTool. Two modes are available: real-time mode checks the entire input as it is typed, while after-word mode only checks once a word has been finished. Suggestions appear directly below the underlined word, so corrections can be made without leaving the game. An ignore list lets players exclude particular words from checks.
Commands in chat control the linter. Only French (fr-FR) is supported at present, and the author states that more languages are planned for future versions. The mod is published for 1.21.7 and 1.21.8 on Fabric, with the latest file for 1.21.8 dated 2026-03-08. It runs on the client alone, so servers do not need it, and it is free to use in modpacks. The mod is not open source, though its source code is publicly available on GitHub and the license is All rights reserved.
Key features
Real-time checking
The whole input is checked live while the player types, underlining flagged words as they are written.
After-word mode
An alternative mode waits until each word is finished before checking, which reduces interruptions while typing.
Inline suggestions
Correction suggestions appear directly below the underlined word in the chat box.
Ignore list
Words placed on an ignore list are excluded from grammar and spelling checks.

Use cases
Cleaner chat messages
Players who want clearer, more correct messages in multiplayer chat can check flagged words before sending.
French writing
Players writing in French can use the fr-FR dictionary for spelling and grammar suggestions in chat.
Who it’s for: Players who write a lot in Minecraft chat and want spelling and grammar help without switching to another program. Because it is client-side only, it can be added to any server without server owners installing anything.
How it compares
Correcteur FR is also a Fabric client-side mod for French chat, open source under the Mozilla Public License 2.0 and published for 1.21.6 – 1.21.8. ChatFilterV1 is a Fabric client-side mod for 1.21 – 1.21.8 under the MIT License, and it is not open source. OGLinter is covered by All rights reserved and is not open source, so it is the option to pick when French is the only language needed and the license matters less than the feature set.
