🗨️ AnonChat Mod
Advanced chat customization for Minecraft 1.21.1 – 1.21.5, 26.1.2 & 26.2
Take full control of your chat experience. Organize messages into separate windows, filter out noise, highlight player mentions, save chat history, and switch between complete configuration profiles — all without leaving the game.

✨ Features
📑 Multi-Window Chat
- Create unlimited chat windows — drag, resize, position anywhere on screen
- Each window holds multiple tabs for organizing different chat topics
- Independent font settings per tab (size, spacing, alignment, shadow)
- Smart edge snapping — windows snap to screen edges when dragged close
🔍 Advanced Filters
Define include and exclude tags for each tab to route messages exactly where you want them:
- Include tags — only messages containing these words appear in this tab
- Exclude tags — messages with these words are blocked from this tab
- Filters work with LabyMod's JSON format — you can migrate your existing filter setup
- Optional: play a sound, change background color, or highlight on match
🔔 Player Mention (Ping)
- Automatically highlights your username in chat messages when someone mentions you
- Choose your highlight color and notification sound (6 sounds to pick from)

💾 Configuration Profiles

🛠 Companion Tool: Filter Editor
The AnonChat Filter Editor is a standalone Windows app that lets you manage your filter tags outside the game.
The problem it solves: Minecraft's in-game text field strips the § color code, so you can't type precise tags like Money§8. The editor writes the JSON directly with literal §, so color-precise tags work.
What it does:
- Browse your profiles from
%APPDATA%/AnonChatMC/profiles/(the mainchat.jsonis protected) - Load daily chat logs or raw Minecraft logs (
latest.log) and see unique messages with occurrence counters - Add any log message as a tag to a filter with one click
- Bilingual UI (English/Polish) — language auto-detected and remembered
➡️ Download the latest version: GitHub Releases → download AnonChatFilterEditor-0.2.4.exe (no Python required)
