ChatTracker

ChatTracker is a lightweight, client-side Fabric mod that automatically records all in-game chat messages into a local SQLite database. Search, filter, and export your entire chat history — across servers, launchers, and play sessions.

🤖 This mod was built with Claude Code by Anthropic.

✨ Features

💾 Automatic Chat Recording

All chat messages are captured and stored locally the moment they appear. Messages are saved asynchronously on a background thread, so there is zero impact on game performance. Supports player messages, whispers, and system messages.

🔍 Powerful Search & Filtering

Open the search screen with a single keybind and instantly find any message. Filter results by:

• Server — Find messages from a specific server
• Date — Browse chat history by date
• Message Type — Player chat, whispers, or system messages

📜 Scrollable Results

Search results are displayed in a smooth, scrollable list that dynamically adapts to your screen size. Navigate with the mouse wheel, drag the scrollbar, or use keyboard shortcuts (Arrow keys, Page Up/Down, Home/End). Results are loaded 3,000 at a time and automatically fetch more as you scroll.

📋 Click to Copy

Click any message row to instantly copy it to your clipboard. Hovered rows are highlighted for easy selection.

📊 Chat Statistics

View detailed stats about your chat history:

• Overview — Total messages, breakdown by type, top servers, top senders, recent dates
• Servers — Message count per server with bar charts
• Senders — Most active players with bar charts
• Dates — Daily message activity with bar charts

📤 Export

Export your filtered chat history as TXT or CSV files for external use or backup.

🌐 Cross-Launcher Support

Chat history is stored in a shared location (%APPDATA%/.minecraft/chattracker/), so your data is accessible across different launchers:

• Vanilla Minecraft (Fabric)
• Lunar Client
• Feather Client
• Modrinth Launcher
• Any Fabric-compatible launcher

🔌 Public API for Mod Developers

Other mods can query ChatTracker’s stored messages through ChatTrackerAPI — no need to implement your own chat storage.

​“json<br>
"suggests": { "chattracker": "*" }<br>
​“

​“java<br>
if (ChatTrackerAPI.isAvailable()) {<br>
List<ChatMessage> msgs = ChatTrackerAPI.search("hello", 100, 0);<br>
int total = ChatTrackerAPI.getTotalMessages();<br>
List<String> servers = ChatTrackerAPI.getServers();<br>
Map<String, Integer> topSenders = ChatTrackerAPI.getTopSenders(10);<br>
}<br>
​“

🌍 Multi-Language Support

• English
• 한국어 (Korean)
