Advanced Chat Filters Reboot
Advanced Chat Filters Reboot rewrites or hides Minecraft chat messages on the client, using filters that match text and replace, recolor or reroute it.
What it does
The mod is an updated port of the original Advanced Chat Filters by DarkKronicle, carrying over the filtering system and fixing several bugs found in the earlier version. Filters can match chat text in many ways, then replace the matched words, change their color, replace the whole message, convert numbers into Roman numerals, or send a message to the action bar. A filter can also narrate a message aloud.
A scripting feature handles text manipulation, but it is disabled by default because scripts add complexity and take up extra resources. Its scope is extremely limited, and several measures are in place to keep scripts secure and stable. Scripts should still be treated with care, and code from untrusted sources should never be run. Filter examples and documentation are available in the project repository and on its wiki.
Advanced Chat Filters Reboot is client-side only and needs Advanced Chat Core Reboot, Fabric API and MaLiLib. The project is open source under the Mozilla Public License 2.0, and its source code is public. Files exist for 1.21.10 and 1.21.11, with 1.21.11-0.0.2 as the latest build, published on 2026-06-12.
Key features
Text filters

Matched words can be replaced with other text, recolored, or swapped for an entire message.
Numeric and special conversions
Numbers can be converted to Roman numerals, and specific text can be converted into a playful OwO style.
